The Bent Twig Published by the American Bonsai Association of Sacramento Dedicated to learning, enjoying and promoting bonsai. March 2011 Monthly Meeting: March 22nd Featuring PETER ADAMS During the years as a bonsai teacher and artist, he has created many drawings, copious writings, including books and articles on the subject of bonsai. Walter Pall called Peter, "the John Naka of Europe". In England his world class bonsai collection at his nursery in Surrey attracted visitors world-wide and many well-known names came to study with him. Peter now lives in Washington state in the U.S. with his wife Kate. Together they have put together a superb collection of bonsai and now travel and teach worldwide. As this site continues you will have the opportunity to see their collection as well as trees that belong to many of their students. Peter offers on-line design and tuition. Peter’s teaching methods are based on his love of beauty and nature. A life-time in the arts and a wonderful artistic talent combined with fifty years in practical bonsai make his work unique. Peter will style a Mendocino Pygmy Cypress from Mendocino Bonsai, and the tree will be raffled off following the evening’s demonstration. This is a meeting you won’t want to miss!!

We were fortunate that he agreed to visit us just one more time before he departs for five years of apprenticeship with one of the great bonsai masters of Japan. One of the hallmarks of an advanced bonsai artist is the ability to design and develop a refined bonsai tree from naturally grown material. With his logical approach and frequent use of a white board to draw many illustrations of his talking points, Peter provided us with the definitive demonstration of basic styling considerations and a prescription for late winter and early spring care of both black pine and red pine. “There’s no such thing as developing a pine real fast,” he said as he showed us a small black pine and a large red pine, both with heavy top branches, irregular knobs and unhealed scars from previously cut branches. Peter’s selection of trees served to highlight the similarities and differences of these two popular species of pines and potential styling difficulties. The Japanese black pine seedling he estimated to be about 8 years old growing in a one-gallon nursery container. The larger red pine tree was obtained from a commercial grower about 10 years ago and put in the ground to grow until it was placed in a shallow container last year. Neither tree had an obvious natural apex, the highest point of a good bonsai design. Both had several similar size bushy top branches. The natural reaction would be to start major pruning, but, to Peter, that wasn’t the right choice. On his last visit to the club, Peter described fall care of pines. This time the subject was winter and spring care, but he continued to emphasize that all styling considerations are irrelevant until the tree is first made healthy by planting it in a proper container and applying good horticultural techniques. Peter divides the annual cycle of pines roughly into thirds with each season having a list of necessary activities to ensure the health of the tree. If pines do not receive routine attention, they can gain too much growth on some branches and die on other shaded branches. Once a branch gets too long, it is very difficult to reduce the branch structure to the proper scale for a bonsai, after three years it is virtually impossible. Grafting branches is a technique often used to correct structural faults in pine trees when nature doesn’t cooperate with growth in the right places. “Some pines will back bud but most don’t,” Peter said. If left unattended, growth problems can extend the styling time by many years. “It’s best to just prevent the problem,” he said. WINTER CARE OF ACQUIRED TREES The winter season is roughly November through February. Winter activities, which already should be accomplished by Valentine’s Day, include: ⇒ Pulling off old needles using the techniques learned last fall, ⇒ Identification of spots that would benefit from side grafts or approach grafting, ⇒ Wiring of major branches to achieve basic shape, ⇒ Cutting back tree branches too big, too long, or not necessary for the design, ⇒ Trimming and turning from time to time so that light reaches all parts of the foliage, ⇒ Attention to healing of scars with trimming and cut paste, and ⇒ Elimination of stress by timely completion of the above steps. Preparation for Grafting: Grafting can be done from December onward, but should be completed by the end of February before the pollen sacs swell and turn bright green, although Peter said that some people with excellent technique are able graft year around with good results. Trees should not be grafted until: (1) the root ball is adequately developed, (2) the tree is properly potted, (3) the tree is properly fed, and (4) the tree is under no stress. If the tree is healthy and ready, complete the graft. If the tree is still being prepared for future grafting, he drew us a diagram and then demonstrated on the tree how to mark the spot by wiring a pseudo-branch where you have decided to insert the graft so that you will remember and be able to style the remainder of the tree around that spot. SPRING AND SUMMER CARE OF ACQUIRED TREES The spring season is roughly from February through May. Spring activities include: ⇒ Repotting, ⇒ Balancing roots, ⇒ Feeding, and ⇒ Elimination of stress. Selection of Soil for Repotting: The best soil for pines is free draining with no organic matter. All nutrients are supplied with fertilizer. Peter uses a blend of pumice, lava, and akadama, (special imported Japanese clay soil available at local bonsai nurseries). The exact blend of ingredients can vary depending upon the preferences of the grower. “My Japanese sensei used only akadama and coarse river sand,” Peter said, adding that “in Sacramento where you have more heat, you probably want more akadama to hold more water.” Preparation of Roots: When first acquired, a tree that has been growing naturally is unrefined. The first thing to do is plant it in a big container so the existing roots have space and small feeder roots begin to fill the container. The shape or material of the container is not important as long as the feeder root development is not impeded by planting too close to one side. There may be a taproot or other big roots in the root ball at first. Peter drew several illustrations showing proper and improper root development techniques over time. “Root work happens over a bunch of repottings,” Peter said. “All of the feeders must come from the trunk with no tap roots. Any big roots with feeders at the end of them must be moved back slowly year-by-year the same way as branches. You can’t do it all at once. Even if you have been working it back and there is only one big root left, it still has to go because it is taking energy from the remainder.” Initial Repotting of Pines Recently Acquired: In general, medium and large pines are repotted every two years, but little young trees can be repotted every year. “ You have to get the old soil out, but it is too dangerous to take all the soil at once or the pine will die. If the old soil is allowed to remain at the center of the root ball, serious problems will result.” Peter illustrated this concept with a drawing of a typical repotting that replaces all of the soil on the outside one-third of the pot. For a tree that is 10 to 20 years old, everything will be OK, but when the tree gets to be about 25 years old, branches will start to die because of the old bad soil compacted in the center of the root ball. At each repotting clear out soil in thirds or quarters depending upon the size of the tree and what you can reach. Make sure to get all the way to the center and remove every speck of soil in that section. On the other sections, only work the outside. Work the replacement soil in well to ensure no air pockets remain. Even on a one-gallon nursery plastic pot, only do one-half at a time. Never bare root the entire root ball. It is too stressful. To take up nourishment, pines need to have a special type of fungus in the soil around their roots. For this reason it is never advisable to completely wash off all the soil from the roots of a black pine even if the tree is very healthy. This fungus appears as a white, stringy material. When repotting, make sure some of this helpful fungus is retained. Depending upon the tree, it should take 2 to 4 years to complete a repotting cycle that replaces all of the old soil with fresh inorganic soil. Repotting of Mature Pines not Recently Acquired: Once the tree roots are refined and all of the old soil has been replaced, you can leave the good inorganic soil in the center section for a long time and only work the edges. Peter suggests caution when selecting a pot just because it is the smallest possible choice. Choose a container large enough so the delicate feeder roots do not dry out and die at the end of a summer day. He says do not use the pot size in calendar pictures of exhibition trees in Japan as a reference for the pot size of a California tree since our situation; trees, climate, soil, care and environmental conditions are much different. AQUISITON BY SELECTION OR COLLECTION OF NEW TREES The first thing to look at when selecting a tree is good health. ⇒ Pests ⇒ Diseases ⇒ General vigor of the tree Each prospective plant should be examined carefully for signs of disease. Pines can be subject to many diseases, such as scale, aphids, spider mites, borers, pine needle miners, damping off, root rot, dieback, blister rust, canker, blight, scale, pine weevil, bark beetles and pinewood nematode to name a few. If the tree is diseased, you need to decide if you want to deal with an established problem. Even healthy pines are susceptible and need to be treated with systemic insecticides and sprays to control insects and disease. Many diseases are easily spread from tree to tree. “The laziest way is to have a healthy tree,” Peter said. Once the tree has passed a health inspection, the tree should be carefully appraised for its potential. A checklist for acquisition includes: ⇒ Age and size ⇒ Trunk diameter and taper ⇒ Roots evenly placed or all on one side or tap root visible ⇒ Main branches with diameter in proportion to trunk and at the proper level, and ⇒ Potential for refinement by wiring or grafting. Idealized Japanese Exhibition Trees: “A lot of the really big trees you see in Japan are collected,” he said. “When you see it in the show, all of the branches are grafted.” Peter goes on to draw an illustration and outline how the branch replacement is accomplished to balance the size of the branches proportional to the side of the trunk. Growing seedlings to maturity is another long term alternative to an exhibition pine. Peter said he started to think about his legacy at age 26 and decided he was too old to start with seedlings. Then, he visited Japan. “There were all these 80 years old guys starting with seedlings,” he said. “Well, when I thought about it, somebody has to start the process.” Using Japanese Techniques on the Demonstration Trees: The little one-gallon black pine demonstration tree is typical of material currently available in nurseries. The tree has been cut back a couple of times and has developed bulges and multiple branches at the nodes. “You have only two options in this situation, leave it and try to hide it or remove it, “ he said “If it’s a practice tree, work with it,” he said. “If you want the full future potential, you must remove it all. You have to have a new apex and there’s not much to use, only one branch right at the bulge and it’s too high. This tree could have a new side graft or an approach graft. The attachment to the trunk should take one year. After the graft takes, cut the top off,” he said. The larger red pine demonstration tree also has severe problems with bulges and branch placement. While it has pleasing aged bark texture and a thick trunk with good curving movement, the branches are randomly placed, bunched together and the whole effect is scruffy with no obvious apex to lead the eye into a pleasing overall design. It needs a whole new top, but first it needs a new larger pot and considerable root work because it has been planted off center and one side has many developed more roots than the other. Peter demonstrated how to do basic shaping on the red pine and placed wire in the places where the future grafts will appear. He will keep a large sacrifice branch just above the grafting site for the new apex to ensure that the water line keeps flowing to that part of the trunk when the graft is finally put in place. “If you have to choose between grafting and repotting, repotting always comes first,” he said. The red pine will be returned to the club each year for the next several years for additional demonstrations so that we can look at the annual steps being taken to change it from an open bushy shrub to an artistically styled bonsai with a proper branch form and a defined apex. RED PINE AND BLACK PINE HORTICULTURAL INFORMATION Peter talked about many criteria to use when selecting new material and caring for the trees. He said care for red pine and black pine are the same. Black pines and red pines can be difficult to distinguish. Bark color can change depending upon growing conditions. Both have bundles of two needles. A black pine has foliage darker and stiffer with a growth bud that is black. Red pine needles are softer and lighter with a growth bud that is fuzzy and reddish. Pinus Thunbergiana “Japanese Black Pine:” is a preferred species for classic bonsai development. A native of Japan, the tree is very robust with moderate growth that can withstand bonsai training stress and is available from commercial sources. The Black Pine is a very vigorous tree commonly grown in Japanese parks and ornamental gardens, tolerating poor conditions, surviving in nature on barren, stony soils. In nature, the tree grows to 50 feet with a spread of 20 to 35 feet. The bark is purplish-grey and, when aged, its craggy and fissured appearance is highly prized. Shoots are black. The needles appear two per fascicle. The exceptionally dark green, five to seven-inch-long needles seen in the garden will reduce to as short as one inch on a mature bonsai with proper care and pruning. The 1½-3 inch female cones that bear the seeds mature in 2 years if left in place but are removed as soon as they appear. In contrast, the male pollen sacs grow only ½ to ¾ inch length and are left in place. Black pine is hardy to USDA zones 5-8. One thing all black pines have in common, big or small, young or old, is they do not like extreme heat, especially at the roots. They are also susceptible to fatal shock if the roots are compromised by exposure to air. Peter grows black pine in 100% inorganic soil. Needle bunches of Black Pine and Red Pine look identical except for the color of emerging shoots at branch tips. Bark color is not a reliable indicator due to age and growing conditions. Pinus densiflora “Japanese Red Pine:” is cold hardy to USDA zones 3-6. Related to a Scotts pine, it has an informal open look and often takes a multi-trunked form slow growing 50 feet but can reach 100 feet. Red pines are often used in Japanese gardens. Bright green needles 3-5 inches long that live for 3 years appear two per fascicle, in bunches along the top of the stem. Emerging shoots are pinkish brown. Two-inch long female cones last for 2 years but are removed as soon as they appear. Bark peels in thin scales to reveal a reddish color. Older bark on the main trunk typically turns gray and color can vary even on different sides of the same tree depending upon conditions. Because of individual variations, the red color bark of red pine is not definitive for identification. Looking at the new shoots is a better indicator. Red Pines is hardy to USDA zones 3–6. Peter grows red pine in 100% inorganic soil. He said red pines are more sensitive to fungus.

Peter Tea – Winter Pine Work What do we do to pines in February? Repot Graft (tree must be healthy for grafting). Begin feeding REPOTTING Good soil – 1/3 pumice, 1/3 lava, 1/3 akadama (Roger Steele shares examples of two small trees grown in two different soil mixes using information from Peter. Porous soil with no organic material will take a lot of fertilizer - more fertilizer, more often and stronger. Two identical cherry cuttings are used. One is planted in a bonsai pot with porous material and no organic material and no akadama. The other is planted in a growing bed with well draining soil, organics and all of the room the plant would want. The potted plant is fed weekly. In one year the potted plant outgrew the growing bed plant by double.) Questions to ask before one begins repotting a pine. Are the roots refined (good root structure, many fine roots)? Are the roots unrefined (fewer larger roots that need to be gradually worked back)? Every time we repot, we work on improving the root structure. Smaller trees can be repotted yearly, larger trees repot every two years. Getting started: Organize all materials first (prepare soil, pot, etc.) Assess tree – do we need to remove old original soil that may eventually choke roots and kill branches? If just the outer soil is replaced, the old soil will continue to break down, compact and prevent water penetration. This will choke out roots close to the trunk of the tree. If necessary to remove old soil, schematically divide the root mass into thirds. Never do bare root on conifers. Carefully remove soil from 1/3rd of the root mass all the way to the center of the tree. For the remaining 2/3rd , just break up the edge of the root mass to encourage roots to grow into the new soil. As repotting is done in the next few years, take a new 1/3 and replace the soil. After 3 repotting, all the old soil will be removed and replaced with good bonsai soil. Options: on younger tree you may replace ½ of the soil, with older trees, may replace ¼ the soil. ABAS BLACK PINE AND RED PINE STYLING Differences between Black and Red Pines: Buds – Red Pines have red fuzzy buds Foliage – black pine is stiffer and greener foliage, red pine is softer and lighter Bark – hard to tell difference Common pests Needle scale Aphids Borers Treat with lime sulfur at certain times of the year Pines are apically dominant, top is strong and bottom is weak. Insects will begin infestation in the weaker part of the tree (bottom of tree). Styling the ABAS black pine: Good bark but tree has reverse taper ½ way up trunk. Choices, for tree to reach its potential, defects must be addressed. Should it be cut off or can we hide the defect? The defect will be removed later and graft in new apex. Approach graft for new apex – must choose branch to use; do not allow multiple branches growing from one node; this will develop into a bulge. Back branch – do not want the first branch to be a back branch; remove this branch. This tree needs a new apex. We need to prepare the tree for grafting a new apex. Leave enough growth on top to pull energy into the grafting area so the graft will take. Also, we need to reduce the top so that it does not take all the energy from the graft. For approach graft, we will have to grow a branch that will reach to grafting point. The other option is to do a side graft. The advantage of the approach graft is that a much larger scion can be used. For the apex, the approach graft will be angled up rather than to the side or down. The tree must be very healthy before grafting. This year repot. Next year graft. Mark the front of the tree with two chopsticks inserted at the angle the tree should be repotted. Wiring: Refined tree: How do we put the wire around the branch? On pines and junipers, the loops do not have to be as close as on deciduous trees. The wire should cradle the needles up at the end of the branch. The branches must be visible to make the tree look older. For our demonstration black pine, this year we will repot, let the tree grow and get healthy. Next year we can graft. RED PINE This tree was purchased from Lone Pine Nursery where it had been grown in the ground for 10 years. Two years ago it was taken out of the ground and placed in a greenhouse to acclimate it to a pot. It is a large old tree. Before beginning styling, we study the tree starting with the base and trunk. At this point, the trunk and base are most important; branch structure will be developed later. Desirable traits are the age of the tree and the well-developed bark. Because it is field grown, there are lots of large roots that need to be gradually reduced. Also there is a large scar that must be healed. To heal properly, the scar will be made concave the cambium around the scar exposed. Seal the wound with cut paste. The branches are too long and too big. Today we will eliminate some of the long branches. Most of the branches are unusable (too big) so we will need to graft. How tall should this tree be? The height of the tree is determined by the angle of the trunk taper. Using the line of the trunk taper at the base, extrapolate up until the lines intersect. This will be the approximate height of the tree. How long until we can show this tree? Repot every two years Begin grafting in two years. It is OK to do all grafts at one time. If approach grafts are used, get faster results because scions are larger and older. Tonight we will mark the grafting points. For this red pine, repot now, fertilize, keep healthy, let grow and get ready for grafting. No de-candling or other routine pine maintenance work. Leave old needles. The one thing to do is to pull old needles from the bottom. Peter will continue work on this tree for the next few years. Members can observe progress and benefit from techniques used to bring a field grown tree to bonsai quality. The tree will be either auctioned or raffled in the future.
