Start seeds inside 3/1-3/31 at 65-70°. Water soil before sowing seeds. Seeds need light to germinate - sow seeds on soil surface and expose them to indirect light (either artificial light or sunlight). Keep seeds moist until germination by watering them with a mist (a handheld sprayer works well for this). Cover seed flat with a dome to keep moisture in (but you should air it out 1x per day for 20 minutes to prevent fungal growth). Days to germination: 7-14. Transplant outside after last frost 5/20-6/30, spaced 12" apart.
To harvest, clip stems 2" above the base of the plant. Do not remove more than 30% of the plant at any one time.
