Cultural Tips:
Grams per 1000 seeds: 3,448
Seed Requirement: 10 g / 1000 plants
Best Sowing Date: November - March
Way of Germination: Cold Germinator
Germination: The sowing must be kept warm (about +18 to 22°C) and moist for the first 2-4 weeks. After this period the sowing must be kept at a cold temperature (between -4 and +4°C) for another 4-6 weeks. It is not so important if the temperature is higher of lower during the cooling period, but the cooling period has to be prolonged because the synthesis of the germination inducer, homonlike acid, slows down or comes to a standstill.
It is beneficial to cover the sowing with snow during the cooling period. After this cooling period the sowing may not be immediately exposed to high temperatures. The most effective temperatures are between +5 to 12°C, even if germination has started. The best location for this sowing, even in March, April and May, is open field, the cold frame or a cold greenhouse.
The directions above do not always show the best results. After the cooling-period this species need a longer time until germination starts. As some seeds do not germinate until the next year, it is important not to throw away the seed boxes too early.
Germination to Transplant: 4 - 6 weeks
Transplanting to salable Plant: 6 - 10 weeks
Fertilization: Medium.
