Sow seeds indoors 6 to 8 weeks before your last spring frost in pots kept at 65 to 70°F. Surface-sow the seeds and lightly firm them in, then place a humidity dome over the containers to maintain evenly moist conditions until germination occurs in 7 to 21 days. Alternatively, use a fine sprinkle of vermiculite over the seed tray to maintain light and moisture balance.
Transplant seedlings outdoors after all danger of frost has passed. Harden off plants by gradually exposing them to outdoor conditions over 7 to 10 days before planting in their final location.
Direct sow seeds in the desired growing location after all danger of frost has passed. Surface-sow and lightly firm seeds into soil; they require light to germinate.
