Start seeds inside 3/1-3/31 at 65-70°. Water soil & mix before sowing seeds. Sow seeds on the top of soil surface and sprinkle with a thin layer of soil mix. Keep seeds moist until germination by watering them with a mist (a handheld spray bottle 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: 14-21. Transplant outside after last frost 5/20-6/30, spaced 8" apart. Plants are perennial but are a bit slow growing so harvest light the first year.
Clip plant at 4" tall to make it bushier. Clip only a few stems in the first year so that it is big enough to survive the winter. In subsequent years, clip stems 4" above the base of the plant. Do not remove more than 30% of the plant at any one time. Over time you will want to remove older, woody stems to encourage new growth. Or divide plants.
