olor is a powerful force in our gardens. Hot reds,
oranges and yellows are energetic, making us feel
warm and happy. They jump from the garden,
shouting, “Hey, look at me!” On the other hand, cool
blues, purples and pinks have the opposite effect, creating
a relaxed feel, receding into the background as if they are
shy and reserved.
Color is very subjective, from the clothes we wear to
the paint we splash on our walls and, of course, the gardens we create. Some of us like to stand out in a crowd
while others want to blend into the surroundings. Are
you outgoing and enjoy bright colors? You’ll love the
flashy magenta and orange color themes on pages 35
and 37. But if you’re more laid-back and enjoy peaceful,
quiet solitude, you might want to grow our elegant white
garden on page 36. Maybe you’ll even want one of each.
Here at Garden Gate, it’s our job to help you explore
what you like and then give you the tools, designs,
photos and inspiration to be successful. In this issue
alone, we’ll share ideas on choosing colors, getting more
color in shade, growing gorgeous geraniums all season
long and more.
Have a great new year!

Stephanie Brown, Maryland
Stumped on how to move a large
container without throwing out your

fall and then again in spring she has to
move a few large containers in and out
of the garage. They’re heavy whether
or not they have soil in them! Dragging

just when you’re trying
to get overwintered
plants going again, try
this tip to keep them
from drying out.
June starts by
planting her overwintered geraniums in a
plastic windowbox
inside. Then she makes
tent stakes of redtwig
dogwood stems left
over from holiday
decorations. The length
of the stems depends
on the size of the geraniums. It’s a good idea
to have a few inches
of space above the
plants for air to circulate. 12 to 18 inches is

usually long enough.
With the twigs in
place, June cuts open a
dry-cleaning bag and
drapes it loosely over
the dogwood stems.
Then she places the
geranium-filled box in
a sunny south-facing
window and gives it
a good watering. The
plastic holds in enough
moisture to see the
plants through until

an eye on them.
concrete drive would chip the ceramic
along the bottom edge. To remedy the
situation, she gets two large flattened
cardboard boxes and lays them on the
ground with the end of the first section
overlapping the end of the second. You
can see how she does this in the photos
below. Stephanie walks the container
onto the first section of cardboard
and pulls it near the end of the second.
Lift this flap up
and place the other
section underneath.

Joann Hemingway,
Missouri
Filling a finch sock
feeder can be a pain.
Joann found a simple
solution: a watering
can with no rose on the
spout. Let the watering
can dry thoroughly
before filling it so the
seed doesn’t stick to the
inside of the can. Then
hold the sock over the
spout and pour the seed
into the sock. No fuss,
Then she picks up the first section,
brings it around and places it under the
flap of the second and pulls the container across the cardboard again. By
keeping the flap of the weighted piece
on top she doesn’t snag the next one as
she drags. Repeating the process gets
Stephanie’s containers in and out of the
garage without any damage.
Once on the cardboard, the container is easier
to move from one section to the next.

Clover mites
no muss. Now all Joann
has to do is tie the sock
closed, hang it up and
enjoy the finches that
come to feed.
Bryobia praetiosa Koch
These tiny arachnids are smaller
than a pinhead and harmless to
people. But after overwintering in
your home, clover mites move outside
in spring and, if populations are large, can
damage ornamental plants and lawns.
Anne Mantey, New York
When you have 35 to
40 roses, there’s a lot
of pruning to do in late
winter. Anne was tired
of the thorns scratching
up her hands and arms.
So she found a way to
avoid most of those
pokes and jabs by
turning a child-sized
plastic swimming pool
into a cane carry-all.
The pool is made of
heavy-duty plastic that
won’t be damaged by
prickly plant debris.
It’s lightweight, too, so
it’s easy to drag over to
the compost pile, even
when it’s full of stuff.
To drag it anywhere,
Anne first needed a
handle. So she cut a
piece of clothesline rope
about 20 feet long and
secured it under the lip
of the pool with duct
tape. She tied the two
ends into a knot tight
against the side of the
pool and placed tape on
either side to make sure
it stayed in place. Then
with two 4½-foot pieces
left over it was easy to
form a big loop handle.
All she had to do was
tie the ends together
in a knot. Now Anne
can haul her pruning
leftovers to the compost
pile with ease.
With its deep fixture, this solar
light can hold enough soil for
a few ground cover sedums.
Light planters
Lois Smith, Virginia
Instead of tossing her
worn-out solar lights in
the trash, Lois decided
to recycle them into
mini containers. And
because they’re on
stakes, she can push
them into the ground,
where they do double
duty as hose guides
at the corners of her
flower beds.
She popped off the
lids easily, then filled
the former light with
soil and added a small
plant or two. She didn’t
need to drill holes in
the bottom of the lights
because they already
had drainage. Lois
has found that ground
cover sedums work
well. Placed at the corners of her flower bed,
it’s easy to keep these
tiny containers watered,
and the stakes help
prevent the hose from
damaging plants in her
garden beds.
Actual size:
.033 in. long
WHAT DO THEY DO? Feeding damage is
most evident in spring and appears as small
meandering paths on leaves. This creates
brown spots in the lawn and can kill foliage on
trees, shrubs and ornamentals. A lush, well-fed
lawn is one of clover mites’ favorite meals.
You’re more likely to actually see the mites
in fall when large numbers congregate on
sunny walls. They’re looking for cracks and
crevices in which to lay eggs.
LIFE CYCLE Clover mites live about a month
and there are usually two generations each
year — one in spring and one in fall, when
temperatures are between 50 and 75
degrees. They lay eggs near the end of
their lives. These eggs lay dormant through
summer and winter. After hatching, the larvae,
which look like miniature adults, go in search
of the same food the adults eat.
SAY GOODBYE The best way to escort
clover mites out of your house is in a vacuum
bag. That way you don’t have to worry about
the red stains they leave behind when they’re
crushed. Just be sure to dispose of the bag
when you’re done because they can escape.
Since clover mites prefer warm, dry areas,
you can keep populations down in the garden
with extra watering. For persistent problems,
use an organic miticide, such as Safer® Brand
Insect Killing Soap. ®

an’t wait to get out in the garden? Me
either! But if you live where the winters are cold, is there any way to get an
early start on the season? Sure.
Sometimes Midwestern winters seem
like they’ll never end, so I talked to
Veronica Lorson Fowler of www.theiowa
gardener.com to find out how she jumpstarts her garden year in zone 5. Here are
some of her tips almost anyone can use.
WARM UP THE SOIL Whether you
garden in the ground or in raised beds,
well-drained, humus-rich soil naturally
warms up sooner than heavy, wet soil.
So in the fall, work loads of compost and
other organic matter into your soil.
And in early spring before you plant
veggies, give your soil an even bigger
boost by covering your planting area
with plastic mulch. Black or colored
sheets, like the red one in photo 1, heat
up in the sun, warm the soil several
When the soil
thermometer
reaches 50
degrees, you
can plant!
(1) Red mulch warms the soil
early in the year, but it also
controls weeds, conserves soil
moisture and helps tomatoes
produce more fruit all summer.

(2) Check the soil temperature at 3 in.
deep for seeds, 5 to 6 in. for seedlings.
Average the temps taken at the same
time in midmorning for three days in a
row to determine when it’s safe to plant.
F E B R U A RY 2 0 1 1 / I S S U E 9 7
degrees and help hold in that warmth
so plants can get an earlier start. Then
begin checking the soil temperature every
few days. When it’s where your plants
need it to be, cut holes in the mulch and
pop them into the soil.
USE A SOIL THERMOMETER Since
most seeds and plants will just sit, and
eventually rot, in soil that’s too cold, a
soil thermometer is handy in spring.
Use one to check the temperature at 3
inches below the soil surface for seeds,
5 to 6 inches for seedlings. Check the
chart that comes with the thermometer
for the minimum and optimum temperatures for your seeds and plants.
Most minimums are between 40 and 60
degrees. There are several styles available
online or at garden centers for less than
$10, but even an inexpensive outdoor
thermometer will be accurate enough.
The dial-type soil thermometer in photo
2 is handy because you can read it
without taking it out of the soil.
PROTECT THE LITTLE ONES So far
we’ve talked about warming the soil, but
air temperature is an issue, too. Impatient
gardeners (like me!) line up to shop for
plants as soon as the greenhouse doors
open in early spring — even if it’s well
before the last frost date. If you nurse
these plants along on your kitchen windowsill, you know how sad and gangly
they grow. Veronica leans an old window
against a south-facing wall and fits it
with plywood ends. This easy cold frame
gives seedlings a sunny spot to grow until
nighttime temps are warm enough for
them to be safely spread around your
garden. For ventilation during the day,
remove the plywood ends. The storm
window in photo 3 lets you open the
window so heat escapes on warm days.
A blanket placed over the window and

home improvement centers.
NO TOOLS REQUIRED Set
four to six bales of straw (good
insulators against cold) on the
ground around tender plants.
A window placed on top lets

moved so plants don’t overheat
on sunny days.

secured to the frame with clothespins will
keep everything toasty on nights that dip
below freezing. Check out two other easy
cold frames you can make at top right.
If you have just a few plants to protect, you may not need a whole cold
frame. Individual protectors may warm
plants just as well. Buy the ready-made
Wall-O-Water in photo 4 at garden centers. It’s set up around the plant, then
filled with a garden hose. The water-filled
baffles hold warmth around the plants
even when the temperatures dip.
Or make the inexpensive version in
the inset by taping water-filled 2-liter
bottles into a ring. Cap the bottles to
keep the water from evaporating or getting murky. As soon as nighttime temps
stay consistently above 55 degrees,
remove the bottles so you can enjoy your
beautiful plants and let them grow bigger.
Spring is a busy time of year, but with
a few of these ideas, you’ll get an earlier
start. And your garden will be well on its
way while other gardeners are still busy
trading their mittens for garden gloves! ®
— Deborah Gruca
Later on, use the straw as
mulch in the garden.
(4) Set up a water-filled plant protector
by first placing a 5-gal. bucket upside down
over your plant. Slip the protector around the
bucket. (It holds the protector upright.) Then fill
the tubes with water and remove the bucket.

To allow more sun in,
remove the labels from
2-liter bottles before using
them. Hold bottles in place
around young plants with a
strip of duct tape.

f you think a colorful shade garden is impossible,
one look at this tree-filled Michigan back yard
should change your mind. Once it was a lot full of
weed trees and brush, but Melonie Ice cleaned it
up and added the path you see in the before photo
below. She might just have thrown in a few hostas
and called it good. But instead, she created the tapestry of color in the large photo at right. Let’s find
out how it all went together.
PATH PLANNING A path is a wonderful thing. It
gives you an even walking surface and divides up the
garden, making it simpler to plan and easier to get
into for upkeep.
Most natural woodland paths meander. They take
you around tree roots and slow you down to enjoy
the cool and quiet of the garden. But when you have
to plan a path through your back yard woodland,
it’s hard to know where it should go. Instead of
drawing a straight line from point A to point B, let
your path wander. Curves and loops, such as the
figure-eight design of this garden path, are good.
ADD SOME HEIGHT Start with low
growers and creepers along the path and
build from there. Make sure to add some
tall plants to the garden. Their height
bridges the visual gap between the lower
plants and tree canopy making the trees
seem less looming. In addition to the bottlebrush buckeye in the back of the garden,
there are a few burgundy banana plants in
containers. The banana’s upright shape and
broad leaves echo the tree trunks scattered
throughout. The containers they’re planted in
give them added height and make it easier to
move them indoors to overwinter.
Now let’s see what else you can do to make
a shade garden great.
(1) Take note of where and how long dappled
sunlight filters through the tree canopy. You
can grow plants that need more sun there.

11/8/2010 8:14:47 AM
Spotlight on plants Even
shade gardens get some daylight.
So watch your garden at different
times of day and take note of places
where the sun comes through the
canopy. That way you can grow a
few plants that prefer more light.
This area near the deck gets a few
hours of sun each morning, enough
that even the big bananas and
yellow Asiatic lilies can thrive. Look
a little further back and you’ll notice
another spot of sunlight. It’s a great
place for a more sun-tolerant hosta,
such as ‘August Moon’, here. Full sun
would scorch the leaves, but a few
hours of daylight keep them a nice
golden yellow.
Path pointers The original
plan for this path called for crushed
gravel to keep with the casual woodland feel of the garden. But Melonie
has two large Labrador retrievers. She
thought the gravel would be more
trouble than it was worth with them
galloping around and tracking it
into the garden as well as the house.
Instead, she decided to go with
tumbled bluestone on a base of sand
and gravel. Its subtle hue has a nice
weathered feel and fades quietly into
the background.
Mix it up Would you believe
that in this smaller area to the right
of the path there are seven different
leaf shapes? Look for heart, oblong,
linear, broad, palmate, round and
frilly. Without a variety of leaf shapes,
shade gardens lose their luster.
Imagine this garden filled with the
same hosta and I think you’ll agree
that it would be pretty boring.
More moss
A nice patch of moss
between the stones helps integrate path and
garden and makes the hardscaping look aged.
Here’s a recipe to encourage moss to grow:
1 gallon of buttermilk
2 cans of beer
Pinch of moss
Shake it all thoroughly and pour it
where you want moss to grow.

here are a lot of pluses to having a shade
garden, not the least of which is cooler temperatures on hot days. But like any garden, you
want to enjoy the view all season. Take a look at

Color combos What’s the best way to get standout color in a shade garden? Chartreuse or gold foliage.
It’s an essential color that provides a sense of energy and
light to what could otherwise be a dark, gloomy area. But
intense colors can sometimes be a challenge to work with.
To really shine, the ‘August Moon’ hosta in this garden
needs a little help from its neighbors. In the illustration
below left, it’s surrounded by plants with similar colors that
don’t really set it off. But in the illustration (and the photo)
at right, it’s surrounded by darker foliage. They really make it
pop, don’t they?
Foliage in similar shades of chartreuse
or gold blends together.
Contrasting colors make this
chartreuse stand out.
Use mulch
Rake leaves
into a pile
and then run
the mower
over them.
Mulch is always a good idea, and with
all these trees there’s plenty of raw material. But a big
garden needs a lot of leaves, so if you don’t have enough,
ask your neighbors for theirs.
Don’t just toss the leaves on the garden, though.
Whole leaves, especially large ones from sycamores or
maples, mat together in the rain and
snow. This can smother plants trying
to grow in spring. Instead, rake big
leaves of any kind into a row and run
the mower over them before you
spread them around.

Pet friendly Pets are
wonderful companions in the
house and in the garden. But
it can be hard to restrain their
enthusiasm. Melonie found that
it was wise to pick her battles.
When one of her older Labs
decided that a patch of ground
cover sedum made a good bed,
she decided the dog deserved
a rest. But that doesn’t mean all garden beds can be
lounged in. You can keep dogs in bounds with invisible
fencing and encourage other play areas, such as the
front lawn. When it’s time to work in the garden, first
take the dogs out to play ball. After a good romp, they’ll
be too tired to get into trouble.

Shade beauties
Want big, gorgeous plants like these in
your shade garden? It’s all in the soil. Before she planted, Melonie
amended the existing soil with a few inches of a perennial mix
made of topsoil and compost from her local garden center.
Be careful about adding soil to gardens under existing trees.
Generally, if you’re going to do this, keep the layer under 2 in. in
depth or you’ll risk smothering the roots of the tree. An annual
application of compost, less than an inch deep, will help improve
the texture of the soil and add the micronutrients plants need to
grow as big and beautiful as the ones here.

Keep trees happy
A big project like a path installation often
takes heavy equipment. Though it’s best to keep equipment like this
away from trees, it’s not always possible. To help trees recover, give them
a deep-root feeding in spring. You can have this done by a professional
or do it yourself, but know that it’s a lot of work for a large tree.
Deep-root feeding delivers fertilizer into holes in the soil around the
tree. Here’s how: Use a bulb auger to drill the holes because it won’t
compact the soil within the hole. So you don’t damage the root collar,
start 3 ft. away from the trunk and drill 2-in.-diameter holes 12 in. deep
and space them 2 ft. apart in concentric rings. The rings should go out
as far as the drip line (or a little further if there’s room).
Using a funnel, pour about one cup of a slow-release 4-1-1 granular
fertilizer into each hole. Then top off the hole with some compost
and water well.
Extend the holes at
least to the drip line.

Amazing
Azaleas
Our regional
picks + the best
tips for success!
ne of the many wonderful traits of azaleas is the incredible variety of plants
available. But with so many colors, sizes
and habits, how do you choose?
I think the best place to start is to find out
what the gardeners who’ve been growing them
for years recommend. That’s why I checked
with the American Rhododendron Society
(ARS). They recommended the six evergreen
and deciduous azalea hybrids above. While
they’re all beautiful, this group of plants also
rates highly among ARS members as healthy,
good-performing plants. (To see even more
regional favorites, go to www.rhododendron.
org/performers_intro.htm.) A couple of notes
on azaleas: These plants grow slowly, so all
heights and spreads are the size they’ll be in 10
years. And look at the zones carefully: Some do
better in cold climates; others take heat better.
Finally, evergreen azaleas hold onto some of
their leaves through winter, replacing them in
spring. Deciduous ones drop them all in fall and
O

have bare stems in winter. On the following
pages, I’ll share ideas on designing with these
stunning plants and the best care to keep them
looking amazing!
Evergreen azaleas
‘ELSIE LEE’ Though stiffly upright, ‘Elsie Lee’
stays just 2 to 3 feet tall and wide. Semi-double
blue-lavender flowers cover the plant in spring.
Handsome, small dark green summer leaves
tolerate full sun and turn brilliant yellow to redorange once autumn arrives. It’s cold-hardy in
USDA zones 6 to 9, heat-tolerant in AHS zones
9 to 1.
AUTUMN STARLITE™ This azalea blooms
heavily in spring, and again more lightly in
midsummer or fall. Encourage more flowers
by giving the plant a second feeding of balanced azalea fertilizer in summer (after the
first one in early spring). In light shade to full
sun, Autumn Starlite produces large white
flowers accented with flecks of pink and

occasional stripes. One of the Encore® azaleas, it’s designed to thrive in warmer zones
than most azaleas — to AHS heat zone 11. The
narrow mildew-resistant leaves turn a pretty
purple in winter. Autumn Starlite grows 3
to 4 feet tall and wide and is cold-hardy in
USDA zones 7 to 11 and heat-tolerant in AHS
zones 11 to 1.
‘HINO-CRIMSON’ Single intense crimsonred flowers last for weeks in early to midspring
— but they’re just part of this plant’s attraction. Its leaves turn bright red in fall and hold
their color through winter. These small leaves
help this azalea tolerate more sun than other
azaleas, even full sun in cooler northern zones.
‘Hino-crimson’ stays just 2 to 4 feet tall and 3
to 5 feet wide and is cold-hardy in USDA zones
5 to 8 and heat-tolerant in AHS zones 8 to 1.
Deciduous azaleas
‘HOMEBUSH’ Semi-double deep pink blooms
show up in mid- to late spring on this very
widely grown upright azalea. Its mildew-resistant foliage turns a great orange-red in fall.
‘Homebush’ grows 4 to 6 feet tall and 4 to
5 feet wide and is the parent of many double
azaleas. It’s cold-hardy in USDA zones 5 to 8
and heat-tolerant in AHS zones 8 to 1.
‘GIBRALTAR’ In midspring, the lightly fragrant orange flower clusters of this azalea
cover the plant even before its leaves emerge.
‘Gibraltar’ gets 4 to 5 feet tall and wide and
is cold-hardy in USDA zones 5 to 9 and heattolerant in AHS zones 9 to 1.
‘NORTHERN HI-LIGHTS’ This easy-to-grow
deciduous azalea is part of the Northern Lights
series, a group of very cold-hardy azaleas developed in Minnesota. ‘Northern Hi-Lights’ has
showy, lightly scented cream-white flowers
with a bright yellow upper petal in spring to
early summer. The leaves start bronze in spring
and turn red in fall. It grows 4 to 6 feet tall, 6 to
8 feet wide and is cold-hardy in USDA zones 4
to 9 and heat-tolerant in AHS zones 9 to 1.

what’s the
difference?
Azaleas are part of the
Rhododendron genus, and
one way to tell them apart
is the number of flower
stamens: Usually, azaleas
have 5; rhododendrons
have 10 or more. Somewhere
in between? It’s a hybrid of
the two.

ecause these beautiful flowering shrubs
vary widely in size and habit, you can use
them in a variety of ways. They’re perfect in
foundation plantings and woodland gardens
but fill lots of other roles, too.
WATCH THE HEIGHT Pay attention to the
mature height of your azalea. Shorter plants
(less than 3 feet) work well in borders mixed
with taller plants or as beautiful flowering
ground covers cascading down a slope. And
growing them in pots is a great way to enjoy
ones that aren’t cold-hardy in your zone.
Azaleas take pruning well, so the taller
ones work nicely as beautiful espaliered specimens trained on a wall or fence, as a standard
planted in the ground or a container. Medium
to tall cultivars can also be planted and pruned
as hedges, reaching their full height in 10 years.
To keep the most flowers, trim the foliage after
flowering is done in late spring so you don’t
remove next year’s flowers.
COLOR CLUES And speaking of color, some
azaleas’ intense hues make them great specimen plants. For even more color, if you have
B
F E B R U A RY 2 0 1 1 / I S S U E 9 7
the space, group several of the same or similarcolored plants. You can see the impact of that
huge mass of color in photo 1. Generally, the
orange ones tend to clash with the pinks and
reds. So don’t plant them too closely together if
they bloom at the same time. And the pictures
on the plant tags can fade with time, so buy
azaleas while they’re in bloom — then you’ll
be sure of the exact shade you’re getting.
LOCATION IS EVERYTHING To make all
those colors really pop, plant a background
of dark evergreens. Even small plants, like the
hostas in photo 1, are perfect companions.
Their green (and even variegated!) foliage gives
your eyes a place to rest from all those hot
hues. And, planted around the base of azaleas,
they help to hide the bare lower branches. Just
don’t place them so they crowd the branches,
or you’ll cut into the azalea’s shallow roots.
For perfect partners, plant other acid-lovers,
such as heather and mountain laurel, nearby.
And if you have a water feature, take advantage of its reflective quality. Plant azaleas near
it for twice the color!

COMMON PROBLEMS AND
HOW TO FIX THEM
CARING FOR
AZALEAS
Good soil prep and planting means you’ll probably see few azalea problems,
but should you see these common symptoms, here’s what to do:
It’s true that azaleas can be troubled by pest
and disease problems. Check out the box at
right for three common symptoms you might
see. But if you provide some basic needs, you’ll
keep your plants looking good.
SOIL Azaleas grow best in moist, welldrained and acid (pH 4.5 to 5.5) soil, but these
hybrids tolerate a wider range. Test your soil,
and if yours has a pH of 6 or higher, before
you plant, work a 6-inch layer of sphagnum
peat moss, pine bark mulch or compost into
the top 12 inches of soil. Or apply agricultural
sulfur at a rate of 2 pounds per 100 square feet
to acidify the soil. (Do this in fall before spring
planting.) Test the pH annually in spring and
if it gets higher than 6, fertilize by spraying
the foliage with an acid-lover formula, such as
Miracid®
. Then fertilize with a balanced, slowrelease granular fertilizer once each spring.
PLANTING The quickest way to kill off an
azalea is to plant it too deeply or in wet, poorly
drain-ing soil. Position it so the top of the root
ball is 1 to 1½ inches above the soil line. In
poorly drained soils or ones with lots of clay,
plant 4 to 5 inches above.
MOISTURE AND LIGHT In summer, regular
moisture and part or dappled shade with some
early morning sun are ideal. In winter, however, that early morning sun tends to warm the
evergreen leaves and buds too quickly after
freezing night temperatures. This causes them
to lose moisture that the frozen roots cannot
replace, drying out the leaves and killing the
flower buds. The best planting sites are on the
north or east side of buildings (as long as the
plant gets morning shade in winter). In zones
where your azalea is marginally hardy, if it’s
not growing near a building, plant it where
it’s protected from strong winter winds by
evergreens or fences. To prevent damage from
drying winds, be sure to water your evergreen
plants deeply in fall before the soil freezes. And
spray the leaves with an antidesiccant, such as
Wilt-Pruf®, in fall and again in midwinter.
Azaleas are truly amazing. By following
these guidelines and choosing the right cultivars for your area, you’re sure to enjoy their
terrific, trouble-free beauty! ®

YELLOW LEAVES
It could be inconsistent moisture Small
leaves and stunted growth are other clues
the roots are either water-logged or too dry.
What to do Plant your azalea so it has
good drainage and make sure it gets
regular moisture.
It could be chlorosis This condition
Chlorotic azalea leaves
is usually caused by an iron or nitrogen
deficiency. (Often the veins will stay green.) A soil pH that’s too high
prevents the roots from getting iron from the soil.
What to do Test the soil. For a pH higher than 6.0, scratch ferrous
sulfate (available at garden centers) into the soil at a rate of 2 Tbsp. for
10 sq. ft. and water it in. (For a quick, temporary green-up, dissolve 2
Tbsp. in 2 gallons of water and sprinkle the solution over the foliage.)
A longer-lasting solution is to sprinkle agricultural sulfur onto the soil
each year. (Follow package directions for rate and frequency.) Do not
use aluminum sulfate to acidify the soil — it’s toxic to azaleas.
FLOWER BUDS DON’T OPEN
It could be cold damage If buds are brown
and dry, they’ve been hit by frost or cold
temps as they started to swell in early spring.
What to do Choose cultivars that are more
cold-hardy or bloom later in the season.
It could be bud blight This fungal disease
is spread by leafhoppers and makes the buds
black and bristly.
What to do Remove the affected buds

and destroy them. You may need to do
this for several seasons to take care of it. Spray all leaf surfaces with
insecticidal soap to kill leafhoppers.
It could be leaf gall In wet, cool spring weather, leaves and buds
swell into fleshy pink-green growths or galls.
What to do Pick off the galls and destroy them as soon as you see
them. Fungicides aren’t usually needed to control leaf gall.

10 tips that’ll work this year!
Grow Gorgeous
Geraniums
Americana®
Red
ne of my favorite garden centers has
table after table of perfect annual geraniums every spring. And as I’m filling
flats, I have a hard time narrowing down my
choices. There are just too many of those
huge flowers in cheerful colors. The problem
I always come up against — and maybe you do,
too — is how to keep those geraniums looking as nice as this vibrant group in photo 1.
To find the recipe for success, I talked with gardeners whose geraniums always look fabulous,
as well as some people in the geranium business. They started by explaining the difference
between cutting- and seed-grown types (find
out more below), then shared some great tips
for success when growing geraniums at home.
Let me show you what I learned.
LIGHT ‘EM UP Geraniums like the sun. They
will flower in as little as four hours a day
but not nearly as well as they do with six or
more. That said, a little afternoon shade
doesn’t hurt where summers get extra hot.
I like buying my geraniums early to get
just the right colors. The problem is I can’t
always put them outside right away — nights

are too cold. Even a few days in a dark garage
can set back flower formation up to three
weeks. In fact, a cloudy spell can do this,
too. So if you’re determined to have geraniums early, make sure to keep them in the
sun when possible and even use a grow light
if you can.
SAY “NO” TO YELLOW LEAVES You may
have noticed that sometimes geranium
leaves turn yellow in summer. They eventually
drop off, leaving a bare, leggy base. There are
several possible causes: too much water, too
little water or not enough fertilizer.
To avoid too much water when you’re growing geraniums in containers, skip the saucer,
which might hold too much water. Go with
pot feet to protect your deck or patio from any
moisture that might run through the drainage hole.
On the other hand, geraniums don’t wilt
as quickly or dramatically as other annuals
do when they’re drought-stressed. When they
do wilt, they’re really dry. To prevent this,
check the soil every week during summer or
daily with containers. If the soil is dry when
you push your finger in about an inch, then
it’s time to water. And when you do water,
thoroughly soak the soil — don’t just wet the
top few inches.
Regular feedings keep geranium foliage
fresh. I’ll tell you more about that next.
FEED THEM! Geraniums just from the
garden center are usually blooming and
may even have a few more buds hiding among
the leaves. To keep your plants producing,
fertilize, fertilize, fertilize.
Mixing a dose of slow-release fertilizer into
the soil or potting mix is a good start. But
flowers will bloom larger and longer if you

also feed them every week with a balanced
liquid all-purpose formula, such as 10-10-10
at full strength.
When temperatures reach 90 degrees, geraniums slow their flower production. To keep
plants on track, switch to a “bloom buster”
product. That’s a formula with more phosphorus (the middle number), which encourages root and flower growth. I like to use
Fertilome® Blooming and Rooting liquid plant
food (9-59-8) from my local garden center.
DEADHEAD FOR COLOR There’s one last
thing that keeps geraniums looking their
best — deadheading. As individual flowers
fade, pull the brown petals out to keep the
flower head looking good longer. Then, when
4
all the flowers on a stem are
dead, take it off so the new
blooms come along more
quickly. In the photo at right,
see how I’m following the
stem down to the bulge? You
snap it off at the joint that
connects the two. Trying to pull from a higher
point can damage the brittle main stem. You
can also snip the stems back below the foliage and they’ll eventually dry up and fall off
on their own.

save your geranium plants from year to year

DESIGN TIPS FOR GERANIUMS
ow that you have gorgeous geraniums, let’s take
a look at how to show them off. In the past, most
geranium flowers were red, and mostly orange-red at
that. But these days there’s a dizzying array of colors
and shades and everything from trailing to upright
habits. Let’s walk through some tips on how to use
these great flowers in your garden.
SHOUT “HEY!” WITH HOT COLORS Do you have
trouble working red-orange flowers into a
planting? You’re not the only one. Take Americana®
Red and Tango™ Deep Red in the photo below, for
example. In a mixed planting this color can either
grab all the attention or make other colors look
sickly. But in this planting the bright, in-your-face
red-orange is a great way to say, “Here’s my front
door!” With about 30 cutting-grown plants growing here it makes a bold statement. But when you’re
bedding out a lot of geraniums, the less-expensive
seed-grown varieties are also good candidates. For
N
5
containers, I like to use cutting-grown varieties.
They’re more expensive, but they tend to have bigger
blooms and leaves.
Having the same red at different levels directs
visitors’ attention to the front door and at the same
time unifies the foundation planting. For the biggest
impact in a bedding scheme, plant your geraniums right next to each other so the flowers weave
together quickly. Some folks don’t recommend close
planting because it helps create the perfect conditions for fungal disease to take hold. I prevent this
from happening by using a soaker hose rather than
watering from above with a sprinkler.
Blue-red is a popular color for geranium flowers.
It wouldn’t work as well here because cooler reds
don’t stand out from a distance the way that hotter
red-orange flowers do. However, blue-red geraniums
do tend to mix more easily with other flower colors.
Try them with shades of pink, white or lavender.

GROW A BETTER BASKET If you see a geranium
spilling over the edge of a container, especially
a hanging basket, chances are it’s an ivy geranium.
Flowers are single and just as colorful as the uprights.
The trouble is, some plants can be leggy and awkward to work into a container gracefully. But I have
some good news for you: Colorcade™, Blizzard®
and Caliente® are just a few of the newer series that
branch more so they’re less gawky looking. I’ve used
Caliente Coral in the basket above. This series is a
cross between uprights and ivies. It doesn’t trail quite
as much as the others but you can see it has a full,
well-branched habit that dips over the edge of this
basket. And all those flowers are nice, too.
If you can’t find these better branching cultivars
and want to encourage more bushy growth on an
ivy geranium you’ve already purchased at the garden center, there are a couple of things you can do:
First, pinch the plants back once when you get them
home. To do this, follow the tip of each stem back
to a junction where a leaf or flower joins the main
stem, then snap it off. The plant will branch from
there to form a bushier habit. Second, grow your
basket in plenty of sun (6 hours or more) to make
sure plants are producing lots of stems.

TRY A NEW TWIST I bet a quick survey of your
neighborhood will turn up at least one terracotta pot or urn with a red geranium, spike and
vinca. You can even find this common combo
already put together in some stores. And there’s
nothing wrong with that, but why not give this
classic look a new twist?
Let’s start with the pot itself. The urn above may
look like it weighs a ton, but it’s actually made of a
composite material that is lightweight and easy to
move. This just makes life easier (and is less expensive than an iron one). Then, replace the old spike
with a softer, fuller ponytail grass. And instead of
vinca, look for a trailing flower. Here I went for
cuphea and petunia. Finally, try a new color combo.
This salmon geranium is just one option in an entire
series of flower colors.
What I like best about this combo is that all these
plants will bloom from spring to frost. But even if
one hits a lull, there will be other flowers to fill in.
With the old formula, if the geranium isn’t blooming, the look gets pretty bland.
All these combinations have been more on the
traditional side. Check out the next page for some
out-of-the-ordinary ideas for growing geraniums.

just showed you one twist on a container classic
But there are plenty of other exciting ways to use
geraniums. Let’s take a look at a few containers we
put together at our test garden last summer.
TRY THE LATEST TREND IN CONTAINERS Succulents like quick-draining soil that’s a little on
the dry side, and so do geraniums — why not pair
the two? You might think succulents would do well
in blazing hot sun, but surprisingly, they don’t. A
little afternoon shade helps keep them happy. These
plants are even less tolerant of overwatering than
geraniums, so make sure they don’t stay too wet and
rot. If you’re concerned about soil moisture, keep the
succulents in their original pots with faster draining
mix and sink them in the container.
Here, the pink-edged Kiwi aeonium picks up
the pink of the geranium’s flowers while the deeper
shades of the echeveria and gasteria provide a strong
contrast of both shape and color. And the geranium’s
bushy foliage hide the echeveria’s leggy stems.
A succulent container doesn’t have to be all about
foliage: Replace traditional trailing plants with a
showy moss rose. It’s just as drought-tolerant as the
other plants here and happily wanders over the lip
of the container, blooming all summer long.

GROW UP AN OBELISK You’ve probably seen
an obelisk in a container before, but sometimes
the plants growing on them look a little spindly in
comparison. On the other hand, if they’re too vigorous, you can’t even see the structure so you lose
that formal feel you were trying to achieve. Ivy geraniums provide the solution. They’re just the right
size. For example, Cascade White above has plenty
of pretty flowers and foliage to blend the obelisk in
with the planting. Americana® Trailing Dark Red,
Temprano™ Pink and Freestyle® Burgundy are some
more of my favorites for growing on an obelisk.
Start by filling the container half full then placing
your obelisk. That way it’s anchored securely and you
won’t have to push the obelisk into the mix. Center
the obelisk if the container is going to be viewed from
multiple sides or place it towards the back if it will
be viewed from one perspective. Add the rest of the
potting mix and you’re ready to plant.
Geraniums don’t have a mechanism for climbing
so you may need to help them get started up your
obelisk. I made a lower ring of twine to hold these
plants up until they started to stretch. In just a few
weeks the plant had grown enough to envelop the
lower portion of the obelisk.

FORGET FLOWERS — GO FOR FOLIAGE Geraniums are grown for their big, bright flowers,
right? Not always. Some cultivars have foliage that’s
showier than the flowers. These two long-time favorites in the photo above are just as easy to grow as
their floriferous counterparts but have interesting
foliage instead. Upright ‘Happy Thought’ near the
back has a creamy centered leaf and some showy
blooms. Not all fancy leaf types have flowers worth
bragging about, so go ahead and snip them off if
they’re too scrawny. In the lower half of the container you’ll see ‘Frank Headley’ trimmed in white.
It’s smaller in size with a more mounded habit and
salmon-pink flowers. If you don’t like these two,
there are many other cultivars available with different foliage markings. For unusual flowers to go
with your out-of-the-ordinary geranium foliage,
check out “Have you seen these?” at right. If you
can’t find them locally, you can get them (and other
specialty geraniums) from the mail-order nurseries
in the list at right.
Now that you know the secrets for growing geraniums, you can come up with your own traditional
combos or create something on the wild side. ®

FLASHY FOLIAGE
Expand your geranium palette with these out-ofthe-ordinary cultivars that are as easy-care as the
garden center types. Help regals and angels along
with sharper drainage: Mix 1 part sand with 5 parts
container potting mix before you plant.
REGALS Also called “Martha Washingtons,”
regals are known for their beautiful flowers. ‘Lord
Bute’ in photo 1 is one of the best known but there
are many others. Try ‘Ballet’ and ‘Empress of Russia’.
ANGELS With smaller flowers and foliage than
regals, angels have more of a trailing habit. Try
‘Michael’ in photo 2 or ‘Imperial Butterfly’.
ROSEBUDS These vigorous upright plants
have fully double flowers. ‘Appleblossom’ in photo
3 is one of the most common, but you might also
like ‘Red Rosebud’.
STELLAR With slender or wedge-shaped
petals, stellar geraniums, such as Graffiti™ Double
Salmon in photo 4, are a little easier to find in
garden centers. You might have to order ‘Arctic
Star’ or ‘Fandango’ — they’re more rare.

agenta. Odds are you either love it or hate
it. This vivid shade of pink has spurred
controversy among gardeners and designers for
years. Well over a century ago, it was referred to
as “malignant magenta.” And some folks still feel
that way about it. But there are so many wonderful flowers that bloom magenta, it seems a
shame to push them out of the garden. So why not
make friends with this vibrant color?
If you like a garden that gives you energy and
gets you moving, magenta is the color for you.
Next to red, it’s probably the strongest color your
eye is drawn to. Sometimes it almost shimmers
or vibrates in sunlight. How your eye reacts to
magenta is determined by a couple of design factors. For example, how much of it does your eye
see at one time? Large blocks of magenta will
vibrate the most. Separating it with other colors,
or even lots of foliage, will help it look calmer.
And its intensity can be enhanced or reduced
by what colors are planted nearby. Other hot
or vibrating colors like chartreuse make it more
intense. Pair it with cool blue or gray, and some of
its strength is taken away.
Below, in “Magenta marriages,” I’ve pulled
together a few of my favorite color schemes featuring this bold hue. But don’t let them limit you.
Just remember that magenta will almost always
draw attention, so use it where you want folks to
look. If you’re still unsure about this color, start
small. Just a few touches here and there can really
add an exciting punch — just what you may be
looking for in your flower border.
Now let’s look at 10 of my favorite plants
with knockout magenta flowers or foliage. I’ve
included some annuals, perennials and even a
shrub. I’ll share tips to make each one a colorful success in your beds and borders. On top
of that, I’ll clue you in on some companions in

that’ll help you perk up failing plants, whether they’re
struggling because you’ve divided them or for some
other reason. It may sound like these practices are pretty

extreme, but believe me, when you do them your garden
will thrive. That said, you don’t want to try them on
the wrong plants. So for each technique, I’ll give a list

So before you dig around and lift

handling the plants much easier and helps divisions get
established in their new homes.
Bury ‘em alive Rather than propagating your woody
perennial herbs by taking cuttings and rooting them
indoors, try this easier way. In spring, remove the lower
leaves from some of the stems while they’re still attached

the mother plant with a sharp scissors
or pruners and pot them for growing

Cut just
through the
bark all the
way around
the trunk.
Cutting the bark breaks the flow of
nutrients between the tree’s leaves and its
roots. This reduces new growth but spurs
fruit set and the forming of next season’s
buds. Don’t cover or tape the cut — it’ll heal
on its own. Do this in spring and the next
year your tree should produce fruit. One
note: Use this measure only as a last-ditch
effort on a vigorous tree. Trying it on a plant
that’s struggling may just hasten its demise.

As a last resort — slash it!
Have an apple or pear tree that’s refused to
bear fruit for several years? Even a healthy
tree in good soil and sunlight sometimes
produces lots of vegetative growth, but little
or no fruit. Here’s a method that will help.
In spring, use a linoleum knife like the
one at right to make just a single cut around
the trunk between the lowest branches and
the ground. Do this about 10 days after the
petals fall or when the new growth is 4 to 6
in. long. The cut should be deep enough to
go just through the bark, all the way around
the trunk, with the ends meeting.

It does help new plants take off more

here’s no such thing as a garden without insects,
or insect damage, for that matter. But not all
of those tiny critters are bad bugs — in fact,
most are neutral, or even good for the garden. Aside
from pollinating the plants, some are also great at
controlling the populations of the bugs that can do
real damage.
So what do you do when you notice insects eating
your favorite plants? Well, first determine how much
damage you can put up with. If bugs are nibbling a
few leaves here and there, maybe it’s not a big deal.
Do a little handpicking or blast them with water
from the hose. But if your favorite rudbeckias are
getting chewed into green toothpicks, take a close
look at the culprits.
WHAT IS THE PEST? For bugs that aren’t visible,
consider putting out sticky traps. If you don’t recognize the pest, do a little homework; once you’ve

identified the pest and learned its life cycle, you might
consider it just a temporary problem. For example,
painted lady larvae feed on my hollyhocks, but I like
the beautiful butterflies, so I’m willing to let it go.
And before you go squishing any old bug on your
plants, make sure it’s not one of the good guys. There
are plenty of beneficial bugs out there.
LET BENEFICIALS WORK FOR YOU On these pages,
I’ll show you nine beneficial insects that eat a lot of
the most destructive bugs. You may have already

BUYING BENEFICIALS
— NO-FAIL TIPS
AVOID BROAD SPECTRUM CHEMICALS Most will kill
beneficial insects along with many of their prey.
You can’t buy most of the insects on these pages, but
that’s OK because they’re common in many parts of the
country. But if you’d like to purchase green lacewings,
or several other beneficials, check out: Gardens
Alive! (www.gardensalive.com or 513-354-1482) or
GardeningZone.com (www.gardeningzone.com or
805-445-9981).
Before you buy, be sure to know which pests you
want to control so you can buy the beneficials with a
real taste for them. Here are some more ways to make
them work best.
before the pest numbers are at their peak, or it may take more
releases to reduce their numbers to a level you can tolerate.
G A R D E N G AT E
GG9730_33.indd 33
WATCH PEST POPULATIONS CAREFULLY Release beneficials
DO RELEASES PERIODICALLY Many beneficials need to be
released several times per year. For instance, green lacewing eggs
hatch and the larvae feed for about two weeks, so for the best
results, you should do three releases, two weeks apart.
BE PATIENT Even after several applications, it takes time for the
beneficials to increase to large enough numbers to have an effect
on pest populations.

Great tips for designing
a garden focused on
just one color!
onochromatic color schemes are some of
the easiest to work with. When you’re shopping, all you need to do is limit your choices
to that color. But flower beds focused on just one
color can sometimes be a bit boring. Follow these
design techniques to elevate your monochromatic
color scheme from ordinary to extraordinary.
THINK ABOUT FOLIAGE, TOO Even in a single
color scheme, it’s unlikely every flower will be exactly
the same shade. Including lots of green foliage is a
good way to blend slightly different hues. Not all
of the magentas in the garden below match exactly,
but the leaves around them pull the look together.
And don’t be afraid to add some colored or variegated foliage, too. Burgundy, a deep shade of red,
fits right in with the vivid magenta flowers in the
garden below. Plus the large striped foliage of the
canna in the orange garden on page 37 makes a
big impact.

AVOID UNIFORMITY With any garden it’s important to choose plants that give you a variety of sizes
and shapes. In a monochromatic garden, because
you’re working with just one color, the form of the
plant becomes even more noticeable. If all the plants
are the same size and shape, and the flowers were
just one color, it would be boring to look at. Keep it
interesting by contrasting the sizes of the blooms, as
well as the shapes of the plants themselves.
CHOOSE YOUR FAVORITE On these pages I’ve
put together three monochromatic gardens. Cool
magenta draws your attention to this shed, but you
could plant this garden at your front door, too. A calm
and relaxing white bed is designed for a shady spot
around the base of a tree. And finally, a border filled
with orange will warm up a back yard. But before
you pick your favorite color scheme, look at all three
to learn more design tips. ®

Stimulating magenta
You
may not want to use magenta where you
plan to relax because it tends to be very
stimulating. But it’s ideal around a garden
shed where you spend your time working.
This garden is designed for full sun. And
most of the plants are very hardy, many
going as far north as USDA zone 5, some
even into 3 and 4. The least hardy is the
ice plant. If it just won’t work in your area,
you’ll find information about lots more
stunning magenta plants in Top Picks on
page 22. One of them, an annual moss
rose call Pazazz Ultra Pink, would make an
easy-to-grow substitute.
Dahlias aren’t hardy in most parts of
North America, so you’ll want to dig and
store the tubers after a frost. Or treat them
as annuals and replace them each spring.

MONOCHROMATIC GARDEN COLOR!
Classic moonlight Plant an all-white garden
where you can enjoy it as the sun goes down, perhaps
around a patio or outside a kitchen or dining room
window. And it’s “all white” even if the garden is not all
about flowers. As flowers come and go, the foliage of
these caladiums and the silvery gray Japanese painted
fern will keep the focus on white. But the magnolia,
daffodils, begonias and hydrangea ensure that this
white garden will have plenty of flowers. Even this hosta
cultivar is known for its fragrant pure white blooms.

height to this garden.

If cannas are not hardy in your zone, you may want
to plant a clump of three rhizomes to get the full

Sidewalk smarts The path features
a warm shade of flagstone to complement
the brick of the house, but its winding shape
brings welcome contrast to the home’s sharp
angles. Starting at the driveway, the 3-ft.wide path is flanked by three ‘Bruns’ Serbian
spruce trees, which embrace the opening and
create a portal into the garden. Portions of the
pathway are flanked with low-growing plants
(or no plants at all) to offer small glimpses of
the walkway from a distance. This provides a
visual break from the intensive planting and
lets people know the path is there. A small
seating area serves as a destination.
Plant smarts There are some awfully attractive plants
that practically beg to be taken home from the nursery. But if
you fall in love with, say, a burgundy Japanese maple and plop it
in this west-facing front yard, eventually you’re going to end up
with some expensive firewood. There are more suitable options
for those conditions, like the smokebushes here. In addition to
attractive burgundy foliage and a modest size, these stalwarts
have airy flowers in midsummer resembling puffs of smoke. The
plants also take well to pruning. Note that the one to the left is
used as a traditional foundation shrub while the one to the right is
pruned into a small multistem tree for greater prominence.

That’s pretty much the situation these folks found themselves in after building their new
house. Facing west, it soaked
up hot afternoon sun. That’s
challenging enough, but the
homeowners didn’t want to
become slaves to the water hose.
For them, it was all about low
maintenance. I know the feeling;
there’s a lot to be said for an
“independent” landscape that
can stand on its own when the
mercury rises. This is a plan for
that kind of landscape.
BEGIN WITH THE SOIL The
bane of many new homeowners
is the “soil” they discover when
first pushing a spade into the
ground: often a light dusting
of topsoil atop heavy clay. On
the other side of the spectrum
is dry, lifeless sand. Whatever
kind of soil you have, try to add
as much compost as possible
before planting (it’s easiest to
have a dump truck deliver the
stuff right to your driveway). In
a seeming contradiction, compost helps sand hold moisture
and clay drain better. Compost
also provides nutrients and beneficial microorganisms. Dig in
compost and any other amendments to a depth of about a foot
throughout planting beds.

Color smarts
These plants share more
than low-maintenance appeal and ability to
withstand hot afternoon sun; they also blend
into an easy-on-the-eyes color palette. Bluegreen conifers form a subdued backdrop,
contrasted repeatedly by dark-foliaged plants
and ground covers. Flowers of blue, yellow
and white set a cheerful tone that’s not overly
busy or jarring. Finally, red roses supply bursts
of excitement without hogging the spotlight.
The result is a charming yet refined look
befitting that of the house itself.
FROM MAJOR TO MINOR In
a larger landscape like this,
it’s best to choose your major
plantings first, then work
down in scale. I envisioned a
base of evergreens to give the
landscape year-round appeal.
Then I added a range of shrubs
and grasses with contrasting
foliage that would last nearly
as long. After that, it’s just a
matter of choosing flowers that
can beat the heat while offering
color from spring through fall.
For a planting plan for the
seating area and path in front
of the house, turn to From the
Drawing Board on page 40.

is why there are numerous specimens in this
planting plan. A midsize cherry plum brings
afternoon shade to the southwest corner of
the house. By itself, the plum would seem
insignificant in such a large yard, but not
when it is joined by two Douglas firs. Closer
to the house, I chose smaller evergreens
that won’t outgrow their space. You’ll
notice that pyramidal shapes echoing roof
peaks predominate in this plan. Yet they are
balanced by rounded- and irregular-shaped
companions.
MAINTAIN YOUR APPROACH
If rainfall is lacking, water beds
deeply once a week the first year.
In later years, you can reduce the
frequency to once every couple
of weeks. Containers, however, may need daily watering.
Mulch beds with 2 to 3 inches of
shredded leaves or wood chips
to keep the sun from baking the
soil and rain from compacting
it. You’ll also need to deadhead
flowers periodically and cut
down grasses annually. That’s
not much to ask for a landscape
that brings value to your home
and a smile to your face. ®

House
front entryway isn’t usually the first place you
think of when someone mentions “garden
getaway,” especially at a new house devoid of
landscaping like the one on page 38. But frankly
this walkway needed a secondary purpose —
another reason for being — because otherwise the
front door probably wouldn’t get a lot of use. So
the idea for a garden getaway was born.
MAKING A GETAWAY A true garden getaway
must be comfortable, inviting and private. Placing
a bench in morning shade takes care of the comfort, while a winding path and wide, circular patio
dotted with containers pretty much wraps up the
inviting aspect. Meanwhile, modest-size shrubs
envelop the setting, providing a sense of privacy
without being smothering. Seated guests can see
and be seen, but they don’t feel like they’re totally
exposed to the neighborhood.
In addition to privacy, plants also help anchor
the dwelling to the surroundings. The hardworking cast of annuals, perennials, shrubs
and trees thrives in the hot afternoon sun
without much pampering. A range of sizes,
shapes and textures makes sure there’s no dropoff in eye appeal.
LASTING LOOKS The blue-green of the conifers
mixes throughout the season with dark-leafed
smokebush, Japanese barberry, and bugleweed.
Blooming annuals and Flower Carpet® roses last
nearly as long as the foliage plants. And the color
quotient really rises in summer, when Shasta daisy,
gloriosa daisy and lavender enter the fray.
Feather reed grasses offer a handsome habit
most of the year for the paltry cost of a late-winter
shearing. They make great companions for shorter
annuals and midsize perennials, ensuring there’s
nearly always something to look at. Containers,
too, bring multiseason appeal. They’re planted
with long-lasting annuals now, but industrious
gardeners might decorate the pots with evergreen
boughs and brightly painted cones in winter. ®

hey say you don’t always appreciate
something until it’s gone. Maybe
that’s why we get more excited about
the ephemeral blooms of a perennial
than the seemingly endless stream of
color thrown our way by annuals. As
much as I like annuals, I sometimes
get weary looking at the same flowers
for months at a time. One option is
to switch out the plants occasionally.
That’s what I did here.
STAGING PLACE I started with a
warm, earth-tone container. It’s handsome enough to stand on its own (but
of course we gardeners wouldn’t have
any of that!). And, at 16 inches across,
it’s big enough to provide room for
larger specimens.
WHAT’S IN THE MIX A container is
only as good as its soil, so fill it up with
two-thirds soilless potting mix and onethird bagged mushroom compost. The
compost helps hold moisture, and it’s a
good source of nutrients and beneficial
microbes. Make sure there’s at least a
¼-inch drainage hole; otherwise, plant
roots may rot in waterlogged soil.
So take a gander at three different
recipes — for spring, summer and fall.
The container is the same; only the
plants were changed to protect the
innocent (from having to look at the
same thing all year long!). ®
Tips for care
• Add slow-release fertilizer to
mix before planting.
• Place container in full sun;
•
provide afternoon shade as
temperatures rise.
Save ivy for later use as a
house plant.

Spring container
Spring is a great time to
plant containers because their portability allows you to
whisk plants to safety if frost threatens. Gardeners can
start this container as early as February in the South and
mid-March in the North. The design features Persian buttercups joined by the purple and yellow petals of violas.
A variegated English ivy softens the pot with its trailing
habit. Persian buttercups are cold-hardy in USDA zones 7
to 11. Treat them as annuals in colder areas or dig up the
rhizomes in summer and store them in peat moss in a
cool, dry spot until replanting the following year.

Summer abundance
As temperatures rise
and spring bloomers are on the wane, it’s time for a new
look. This one features a lush tropical theme that will keep
going all summer long. While it’s hard to ignore the bright
orange blooms of the New Guinea impatiens, this design is
really about foliage. There’s the upright architectural habit
of the variegated mother-in-law’s tongue (bonus: you can
overwinter it as a house plant). Coleus energizes the design
with its fresh green-and-white foliage. And New Guinea
impatiens impress not only with bold blooms but also with
contrasting dark, serrated leaves.

Aquasav basket liners
You may have had problems keeping hanging
baskets watered in the past, but the new
Aquasav™ basket liner will help. As the inset at
right shows, it’s layered like a sandwich with
a piece of 100 percent post-consumer recycled
plastic between two layers of coconut coir. The
plastic stops some of the water from running
through the liner, which helps the potting mix
inside stay moist longer. We compared Aquasav
to a regular basket liner last summer and noticed
a definite difference. The potting mix in the
regular liner dried out well before the mix in this
new one did.
Bottom line Less time watering? Fantastic!

M Brace
This is about the easiest way to build a raised bed that you
can find. You don’t need any tools, just lumber cut to size.
Each corner brace is made of recycled steel and is 13 inches
tall and 11 inches wide. The braces can hold four 2x4
pieces of lumber up to 12 feet long. To build the bed, just
slip each board between the inner brace and the outer decorative one. Then fill it with soil and you’re ready to plant!
There are eight designs, including the squiggle
at left and the swirl at right, so your new
raised bed can be stylish, as well
as functional.
Art of the Garden also
sells plant labels made
of the cut-out steel
pieces. A set of six is
$12. Use a permanent

spray with a sealant,
such as Permalac, so
they won’t rust.

Most potting mixes have a lot of peat moss in
them to provide the quick drainage plants need
in containers. And while you may know that it’s
possible to burn peat, did you know that the peat
sitting in those containers on your deck is combustible? It’s true. While it’s not common, in the
right circumstances a container full of plants can
turn into a fire hazard.
Several home fires within the last few years
have been attributed to peat moss that got too dry.
To prevent this from happening at your house,
keep containers, especially those sitting in full sun
all day, well maintained. Water and remove any
dried or dead plant material as soon as you notice
it — even at the end of the season. Also, don’t let
anyone put their cigarettes out in your containers.
When you’re storing bags of potting mix in the
garage or tool shed, don’t place them next to
another combustible, such as a gas can.

Don’t forget to wear gloves when you’re working
in the garden, and not just because they keep your
nails clean. You need to protect yourself from rose
gardener’s disease. It’s caused by the soil-borne
fungus Sporothrix schenckii. The fungus can enter
your bloodstream through small nicks and cuts.
Most of the time it causes skin infections, but in
extreme cases affects the lungs. This disease can
be hard to diagnose, as symptoms can take three
weeks or longer to appear. Initially, small, painless
pink or purple bumps show up on the skin where
the initial cut or abrasion was. They’re followed
by larger bumps that resemble boils and are very
slow to heal. Rose gardener’s disease is not contagious, but if you get it, you’ll need a prescription
medication to get rid of it.

WINTER ANNUAL An annual that germinates in fall, spends the winter as a seedling,
then flowers, sets seeds and dies by summer.
Many weeds, such as henbit and chickweed,
are winter annuals. Most garden plants called
“winter annuals” are actually just plants whose
seeds or flowers tolerate cold temperatures.
Easy fork fix
I broke the handle
on my favorite
spading fork. Can I
repair it or should I
replace it?
Split wood repairs
rarely hold very
well. So head to your
hardware or farm
supply store and buy a
new handle. To help the
salesperson, be sure to
take the old fork along
with you.
When you’re ready
to replace the handle,
soak the ferule end of
the new handle (see the
photo at left) in hot tap
water. Let it soak for at
least half an hour. This
will soften the wood,
letting the tang slip in
further when you put
the cast metal fork on
the handle. Then, as the
wood dries, it will grip
and hold the metal fork
much better.
While that’s soaking,
grasp the old handle
and use a hammer to
knock the fork off.
Now you’re ready to
put the fork on the
new handle. Push the
tang into the predrilled
hole as far as you can.

Q
The trunk of my
star magnolia
(Magnolia stellata) is
showing a crack. Can I
keep it from splitting?
The first step is to
reduce the weight
that’s pulling the crack
open. The illustration
below shows which
branches you could
remove from this
cracking tree to help
take away some of the
weight. You may want
to take a few branches
off the other side to balance the look.
A
Pick up a piece of
threaded rod (½-inch or
larger in size), two nuts
and two washers, available at most hardware
stores. The rod has to
be long enough to go
through the trunk, plus
about 3 extra inches.
You’ll need a drill with
a bit that’s 1⁄16 inch
smaller than the rod
and long enough to go
through the trunk.
Drill the hole just
below the crotch. Trim
away the bark to countersink washers on both
sides of the tree. Next
slip a washer and a nut
on one end of the rod
and screw it down so
about 2 inches of rod
show. Insert the end of
the rod without the nut
into the hole and use a
pair of gripping pliers
to turn it through to the
other side. Pliers will
damage the threads, but
since the nut is already
on that end of the rod,
it won’t matter.
Once the rod is
through the trunk, put
on the other washer and
nut. Tighten it down
snug, but don’t force

it. The washer and nut
should only sink into
the wood slightly.
Cut off any excess
rod so the tree bark will
grow over the washers
and nuts — exactly
what you want to
happen. Your tree can
now withstand snow
and wind much better.
Faded velvet
Deb Hock, Arizona
Q
Since I moved my
purple velvet plant
(Gynura aurantiaca)
indoors for the winter
the new growth is
green. Why?
This fast-growing
tropical needs
bright light to keep
its deep purple color.
Indoors, grow it in a
south- or west-facing
window. If the new
green foliage is objectionable to you, go
ahead and snip it off.
Not only will that get
rid of the green portions, but as the plant
grows, it’ll make the
plant much more dense
and bushy, too.
A
Put the final washer and nut on the end of
the 1⁄2 in. rod that was not damaged by the
pliers after you turn it through the trunk.
Drill the hole near
the bottom of the
cracked crotch.
Bark will grow over the wound
if you countersink the washers
on both sides of the trunk.

Clammy groundcherry
Physalis heterophylla
WHAT IT LOOKS LIKE The edible fruit of this
perennial is the best ID. In the illustration at right
you can see the papery husk that holds one
rounded fruit, which turns golden yellow when
ripe. Clammy groundcherry blooms from spring
until late summer, so you could find ripe fruit
at almost any time during that period. Yellow
flowers hang like bells, but unless you pick one
you may not spot the purple center shown in
the illustration.
Growing 8 to 30 in. tall, this North American
native spreads by seeds and by underground
rhizomes. Each plant usually has
lots of side branches, and the leaves
can be up to 4 in. long. The leaves,
stems and even the husk on the fruit
are covered with fine white hairs.
Touch any part of the plant and
you’ll notice that the hairs have a
sticky feel.
But don’t wrap a
wisteria vine around
spindles — they’ll
eventually break.
Winding wisteria
Kent Gragg, Illinois
Q
How do I get
American wisteria
(Wisteria frutescens) to
cover my pergola
without damaging the
wooden rails?
Wisteria stems can
grow to the size of
small tree trunks.
To minimize damage,
tie a young stem to the
outside of the post with
strips of fabric. Once
it gets to the top and
spreads out it can support itself. Don’t weave
the stems through
railings or lattice as in
the photo above. As
the stems grow they’ll
break the wood.
A
Time to sow seeds
Maggie Axser, Ohio
Q
The snow plow
damaged my lawn.
When can I put down
bluegrass seed?
You can sow the
seed on frozen
soil. When the ground
thaws, the melting ice
will keep the soil moist,
helping the seeds to germinate and grow.
If the plow scraped
deep, you may need to
add topsoil or compost
A
to level the area first.
(Otherwise, you’ll have
ruts or ridges in the
lawn when it comes
time to mow.)
Then sow the seed
and sprinkle about a ½
inch of soil or compost
over it. The rest is up to
Mother Nature. But if
the weather turns dry,
keep the soil moist until
the seed sprouts.
cherry prefers full sun, you might find it growing
in part shade, too. And it tolerates moist to dry,
rich or poor soil. Since this weed is perennial, it
resents areas that are frequently cultivated, so it
grows mostly in perennial beds and shrub borders. Clammy groundcherry is found mainly in
the eastern three-quarters of North America,
but also extends into the Pacific Northwest.
Toni Ellison, Wyoming
Q
A
A mature plant

root structure.
HOW TO GET RID OF IT Tilling the soil when
you see seedlings will keep it under control. But
once the roots are established deep in the soil,
you’ll need to dig up the plant, making sure to
get all of the roots. Any pieces left behind can
sprout. Herbicides are effective, although in
some areas this perennial is becoming resistant to glyphosate and may require strong or
repeated applications. ®

Calibrachoa hybrid
Callie® Painted Coral is one of my
favorite calibrachoas. Its showy flowers
of coral and soft cream blend well in
mixed plantings. And it even looks good
on its own in a hanging basket.
This cultivar is covered in blooms for
most of the summer. To make sure I have
plenty of flowers I start with a potting
mix that has a slow-release fertilizer.
Then, beginning the end of June, I use a
balanced, full-strength fertilizer weekly.
There are many other colors in the
Callie series, too. Painted Coral was
introduced by Fischer in 2007.
Goldwell speedwell
Veronica prostrata ‘Verbrig’
Here’s a sweet little ground cover with
pretty variegation. Sunny yellow and green
leaves form a colorful mat in the photo
at right. Spring brings pretty blue flowers
like the one in the small photo. But there’s
no need for deadheading; Goldwell is selfcleaning. This is a vigorous plant but not
aggressive and will form a puddle of color
in the front of your garden.
A heavy layer of snow may mat the
plant down and make it slow to recover
in spring. So after the snow has melted, be
sure to gently lift and fluff the leaves with a
rake or your fingers.
Goldwell was introduced by Blooms
of Bressingham in 2006.

Monarda ‘ACrade’
Grand Parade™ has many things that
make it memorable. But the best thing
about it is the complete lack of powdery
mildew, often a problem with bee balm.
Its rich pink flowers last for a week
or two. When that first batch of blooms
goes down, cut the stems back to the
first node (the place where the leaves
meet the stem) below the flowers. In a
few weeks, the show starts again.
This petite bee balm was introduced in
2008 by the Morden Research Station
in Manitoba.
‘Golden Meadows’ hosta
Hosta hybrid
‘Golden Meadows’ is a “Wow!” hosta in
early spring and summer. Leaves emerge
from the ground like rolled cigars with a
center stripe of creamy white, blue-green
and light green. This tricolor variegation
stays until summer’s warmer temperatures
cause the creamy white center to change
to light green. The more sun ‘Golden
Meadows’ gets, the lighter the center stays.
I’ve even noticed this difference on a single
leaf when part of the plant gets more light.
This cultivar from Darwin Plants was
introduced in 2004.

Hydrangea macrophylla
This may be one of the small hydrangeas,
but it has big blooms — up to 9 inches
across! Mophead flowers start out bright
white early on and blush pink with age.
I think it’s one of the best of the Endless
Summer® line of hydrangeas because it’s
so reliable. Pruning is simple. Just remove
any dead branches in spring. And while
it blooms on both old and new wood,
‘Blushing Bride’ blooms earliest on old
wood. The flowers that form on new wood
take time to get going and won’t show up
until later in the summer.
Blushing Bride has been in garden
centers since 2007 and was introduced by
Bailey Nurseries.

favorite combo: made in the shade
G
ardens with a little shade
don’t have to be dull — just
look at the vibrant color in this
early summer garden! The hot
chartreuse foliage of ‘All Gold’
hakonechloa and ‘Goldflame’
spirea infuses light into this
shady spot. Pair that strong
color with the vibrant orangered flowers of the wax begonias
and you’ll spot this planting
from across the street! But just
like a loud neighbor, gaudy color
combinations can be grating on
your nerves. So the deep colors
of the coral bells, along with
begonias’ bronze-hued foliage
tone this sizzling combo down
just a bit.
CONTRAST LASTS Though
the flowers of the spirea will be
gone by midsummer, the rich
begonias will keep coming until
frost without deadheading.
But even without those bright
blooms, this planting shines. The
bold, silver-kissed foliage of the
coral bells contrasts sharply with
the fine leaves of the spirea and
begonias, and the long, wispy
blades of the hakonechloa.
Distinctly different leaf textures
keep this scene interesting all
season long.
COOL AND SHADY Not only
do these plants look fabulous
together, they all thrive in similar
conditions. Moist, well-drained
soil keeps them all happy. And
though all can handle full sun
(the spirea will bloom better with
more light), they’ll also do well
with some protection from hot
afternoon sun. Let’s take a look
at how to get the best from each
of these easy-care neighbors.
SPIREA Give this shrub consistent moisture the first year
after it’s planted; after that, it’s
more drought-tolerant. For a
fresh look, you can shear the
plant back after the blooming
finishes, though even that’s not
required. It’ll look tidier and you
may get a smaller rebloom later
on. After several years, if the
plant gets large and gangly, cut
it back to 6 inches tall in early
spring. Don’t worry, it’ll quickly
come back, flower better and be
more compact.
HAKONECHLOA With its
upright habit, ‘All Gold’ is
a valuable member of the
hakonechloa family. Make
sure it gets regular moisture,
especially the first year, and this
glow-in-the-dark beauty shines
happily. It can take more light,
where it’ll be gold rather than
chartreuse, but can scorch in
very hot-summer areas. Give it
a good haircut in early spring to
make room for new growth.
CORAL BELLS There’s not
much to do for this pretty perennial. You may wish to deadhead
the airy flowers when they fade
for a tidier look, but it’s not
necessary. If you live in USDA
zones 4 or 5, a 2-inch layer of

organic mulch will help keep
the roots from being heaved out
of the ground in winter. (Push
the crown back into the soil
with your toe if this happens.)
A quick trim of dead leaves
in early spring will produce a
clump of fresh new foliage. And
if flowering starts to decline
after three or four years, divide
the plant in spring.
WAX BEGONIA This tender
perennial is treated as an annual
by most gardeners and, as
with many annuals, will bloom
like mad all summer. Its waxy
leaves make it pretty droughttolerant, but it’ll flower more
with regular moisture. About the
only problem comes when wax
begonias are planted too closely.
Follow the spacing listed on the
tag to prevent fungal disease
caused by poor air circulation
and they’ll be bursting with
blooms until frost. ®

“I want my garden to go

I cannot bear to think of it as a place
that may be tenanted only in the easy months.
I will not have it draped with Nature’s dust sheets.
That is why I waged this battle for winter flowers…”
