Sow seeds indoors 6-8 weeks before your last frost date. Surface sow the tiny seeds and press them in lightly, as they require light to germinate. Keep the soil at 75°F until germination occurs, which takes 5-14 days. After sprouting, drop temperatures to 60-65°F. Water from below by placing seed trays in a larger water tray and allowing drainage; this method prevents damping off and avoids disturbing the delicate seeds.
Transplant seedlings outdoors about 1-2 weeks after your last frost date once they are established and hardened off. Space plants 1 inch apart for dense growth.
