TRANSPLANT LINERS
Pot Size: Transplant liners into quart (1 litre),
6-inch (15 cm) or 1-gallon (4 litre) pot with one
cell per pot.
Media: Porous soil with good drainage is
required.
Vernalization: Vernalization is not required for
any of the Star™ series Dianthus. These plants
can be purchased in the fall and bulked in the
final container prior to vernalization for a very
showy spring flush of flowers, or unvernalized
liners can be planted outdoors in spring for
finished flowering plants in June.

Media pH: Optimum not tested. Standard
for 1-gallon (4 litre) pot is 5.5 to 6.5.
Media EC: Optimum not tested. Standard
for 1-gallon (4 litre) pot is 1.5 to 3.
Moisture: Plants should be grown on the
dryer side due to fine root system and tendency
toward Fusarium.
Light: Full sun.
Fertilizer: While actively growing, plants
perform well with a constant liquid feed of
150 ppm nitrogen.
Supplemental Lighting: Not required except
if forcing for spring sales from unvernalized
liners; add 4-hour night interruption lighting from
10:00 p.m. to 2:00 a.m. for earlier, more uniform
flowering. Not needed for vernalized production
or unvernalized spring planting for early summer
sales.

SCHEDULING RECOMMENDATIONS
These plants can be purchased in the fall and
bulked in the final container prior to vernalization
for a very showy spring flush of flowers, or
unvernalized liners can be planted outdoors in
spring for finished flowering plants in June. Exact
timing for spring flush and flowering is dependent
upon local weather conditions. See table below
for weeks to flower from unvernalized liners
planted in spring based on outdoor trials in
