Germination: The sowing must be kept warm (about +18 to 22°C) (about 64 to 72°F) 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) (between 25 and 39°F) 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 (41 to 54°F), 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.
