Dianthus F1 Diana

Family:                   Caryophyllaceae
Use:                    Outdoor containers and pot, suitable for borders and beds.
Plant type:          Annual
Height in pot:      15-20 cm (6-8  in.)
Garden height: 20-25 cm (8-10in.)
Seed count: 1,100-1,250/ gram (30,000-35,000/oz) Seed  count  varies  by colour  and seed lot.

Germination:
Media  pH 6.0
temperature 21-24ºC (70-75ºF) EC 0.5
Ammonium based fertilizers  are  not recommended, use  calcium based fertilizers  instead.

Stage 1: radicle emergence
Seeds may  be covered lightly with vermiculite. Radicle  emergence will take  place in 2-4  days. Keep media moist  but do not overwater.
Light is not  necessary for germination. Dianthus is very sensitive to high  salt levels in stage 1 and 2.

Stage 2: expanding stem and cotyledons
Keep media moist,  lower  night  temperature to 18ºC (65ºF).
Under low light conditions supplementary  lighting is advised to promote compact strong seedlings.

Stage 3: development of first true  leaves Keep media moist.  Temperature days  18-20ºC (65-68ºF).
EC 0.5-1
Growth regulators: Cycocel( 1-2  cc/ltr), Bonzi (0.5  cc/ltr) or A-rest.
Treatments can  be applied at the  fourth  true  leaf  stage.

Stage 4: finishing/holding stage
Temperatures can  be  dropped to  15ºC (60ºF).  Higher temperatures will result  in more use  of growth regula- tors to prevent stretching.

Growing on:
After 5-6  weeks  plants can  be transplanted, it will take 9-10 weeks  to finish in the  pack.
Allow an  extra  2 weeks  for 10  cm (4 in.) pots.
Media: a well-drained, porous media is best  to prevent over watering.
pH 6.0-6.5
EC. 1.0-1.75
Moisture: allow  media to dry between watering, do not allow  plants to  wilt  severely, this  will result   in  yellow leaves and serious setback in growth.
Light: Increase total  light  energy to  promote early  flo- wering, daylenght  extension is  not  necessary but  will promote bud  set.

Pests:
Spidermites, Thrips and whitefly.

Diseases:
Alternaria leaf  spot,  Fusarium wilt.

Growth regulators:
Dianthus interspecific is sensitive to:
– Cycocel,  spray  up to 5 cc/ltr.  Some  varieties will show leaf  damage at high  Cycocel  levels.  Also a drench of
3cc/ltr. will be effective.
– Bonzi as spray  or drench
– Dif

Scheduling:
12-14 weeks  for  packs. Pot  production, 10  cm  (4 in.), may  need an  additional 2-3  weeks.
