Sowing Direction:

(15) Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Seeds must be covered thinly. Do not cover very small seeds, but tightly press into the earth. Keep in cooler conditions after germination occurs.

Best Sowing Date
(northern Hemisphere, Field condition):
Anytime
Sowing Time Hint: Germination occurs in 1-2 weeks.
Sowing to Germination: 1 - 2 weeks
Germination to Transplant: 4 - 6 weeks
Transplanting to Potting: 6 - 8 weeks
Cutting back at Transplanting: Not Necessary.
Container Size(s): 1-2 plugs per 11/12 cm (4 1/2") / 2-3 plugs per 15 cm (6")
Vernalization: Some flowering will occur the first year without vernalization, but improved flowering will occur the 2nd year; and 3-10 weeks of cool temperatures might benefit fuller flowering in the first year.
Forcing: There has been no research, but an obvious place to experiment - following vernalization - would be raising daytime temperatures to 60° - 65°F (15° - 17°C). Provide 16 hours of continuous lighting. During the short days of winter, provide a night interruption lighting of 4 hours between 10:00 p.m. and 2:00 a.m. Some later flowering species can be forced in 14 - 16 weeks and perhaps sooner at warmer temperatures. Further experiments are warranted.
Fertilizer: Medium (150-200 ppm)
