Growing On:
Grams per 1000 seeds: 1,429
Seeds per Gram: 700
Seeding Recommendation: 5 g / 1000 plants
Sowing Rate: 3-4 seeds per cell
Plug tray recommended size(s): 72 or 128
Germination: Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Seeds must be covered thinly. Keep in cooler conditions after germination occurs. The germination might be slower and more irregular. This poses no problems.
Best Sowing Dates: Anytime
Sowing to Germination: 2 - 3 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to Salable Plant: 6 - 10 weeks
Cutting-Back at Transplanting: Cut back 1-2 times; once at transplanting; once again 4 weeks later to keep more compact
Container Size(s): 1-2 plugs per 11/12 cm (4 1/2'')
Vernalization: A prudent recommendation would be to provide 6-12 weeks at an average daily temperature of 40°F (5°C). Exposure to cold may not be necessary for flowering but might improve quality.
Forcing: This species is not a suitable candidate for forcing.
Fertilization: Medium (150-200 ppm)
