Sow seeds indoors 6-8 weeks before your last spring frost. Press seeds lightly onto the soil surface (they require light to germinate) and cover with a humidity dome or fine vermiculite. Maintain soil temperature between 65-70°F and keep conditions evenly moist. Seeds typically sprout within 14-30 days.
Transplant seedlings outdoors after all danger of frost has passed. Since this variety is hardy only to zone 5, timing matters; wait until nighttime temperatures consistently stay above freezing before moving plants outside.
You can sow seeds directly in the garden after all frost danger has passed. Press seeds lightly into prepared soil and keep moist until germination.
