1,0 g = 30000 seeds.
Grams per 1000 Seeds: 0,025
Seeds per Gram: 40000
Seeding Recommendation: 0,5 g / 1000 plants
Sowing Rate: 20 seeds per cell
Plug tray recommended size(s): 128, 288
Germination: Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C. Do not cover the seed but tightly press into the earth. 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 - 6 weeks
Transplanting to Salable Plant: 6 - 8 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 ; 2-3 plugs per 15 cm
Vernalization: A prudent recommendation would be to provide 6-12 weeks at an average daily temperature of 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).
