Sow on the surface of the soil, indoors from mid-February to late March for transplanting (or direct sow) 3-4 weeks after the last frost – around late-April. Direct sowing outdoors into May. Seeds germinate for 10-14 days. If starting indoors, seeds benefit from vernalization: Place seeds on the surface of moistened, sterilized seed starting mix in pots, and place pots in zip-top plastic bags inside the refrigerator for 2 weeks. Then move pots to bottom heat and maintain soil temperature at 21-25°C (70-75°F) until germination. Provide bright light.
