Dianthus F1 Chiba
Use: Outdoor containers and pot, suitable for borders and beds.
Plant type: Annual
Height in pot: 20-25 cm (8-10 in.)
Garden height: 25-35 cm (10-12 in.)
1,100-1,250/ gram (30,000-35,000/oz) Seed count varies by colour and seed lot.
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).
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.
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.
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 flowering, daylenght extension is not necessary but will promote bud set.
Spidermites, Thrips and whitefly.
Alternaria leaf spot, Fusarium wilt.
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
12-14 weeks for packs. Pot production, 10 cm (4 in.), may need an additional 2-3 weeks.
Sowing Potting Flowering wk 2 wk 8 wk 19/20 wk 4 wk 10 wk 21/22 wk 9 wk 14/15 wk 24/26
Ensure best light conditions especially early season and grow dry to restrict and harden growth. Transplant on time.
