Sowing method: Year-round in a seed tray, first give 2-4 weeks of warmth (18-22° C), then a cold period in, for example, the refrigerator (+4° C) for 4-6 weeks, then gradually warm up to room temperature, after which germination will follow. The seeds germinate irregularly over a longer germination period. Therefore, do not discard the seedlings too soon. Sowing directly into the garden is also possible; in that case, simply let them overwinter, and germination will occur in spring.
