Plug tray recommended size(s): 72 / 128
Sowing Direction:

(8) These perennial seeds germinate very irregularly over a long period. Lower temperatures of less than +5°C [41°F] are very effective. Seed trays should not be discarded prematurely. Constant moisture must be maintained. Do not leave in direct sunlight. For Alstroemeria we recommend to keep sowing for 3 weeks at approximately +30°C [86°F], then 3 weeks at +5°C [41°F], then at +21°C [70°F].

Best Sowing Date
(northern Hemisphere, Field condition):
late winter - late spring
Sowing to Germination: 6 - 10 weeks
Germination to Transplant: 4 - 6 weeks
Transplanting to Potting: 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 (4 1/2") / 2-3 plugs per 15 cm (6")
Vernalization: No vernalization required for 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)
