Cultural Tips:
Grams per 1000 Seeds: 3,333
Seeds per Gram: 300
Seeding Recommendation: 10 g / 1000 plants
Sowing Rate: 3 seeds per cell
Plug tray recommended size(s): 72, 128
Germination: These seeds germinate rapidly depending on species and origin. If germination does not occur after 3-4 weeks a cooling period of 2-4 weeks is recommended.

Scheduling:
Best Sowing Dates: November - March
Sowing to Germination: 5 - 8 weeks
Germination to Transplant: 3 - 4 weeks
Transplanting to Salable Plant: 6 - 8 weeks
Cutting-Back at Transplanting: Not necessary

Growing On:
Container Size(s): 1 plug per 8/9 cm (3 1/2''); 1-2 plugs per 11/12 cm (4 1/2''); 2-3 plugs per 15 cm (6'')
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: There has been no research on ALLIUM senescens, 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 with ALLIUM senescens.
Fertilization: Low (100-150 ppm)
