Dianthus F1 double flowered Grace
Use: Outdoor containers and pot, suitable for borders and beds.
Plant type: Annual
Height in pot: 15-20 cm (6-8 in.)
Garden height: 25-30 cm (10-12in.)
Seed count: 750-1,200 seeds/ gram (21,000-34,000/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 flo- wering, 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.
