Direct seed (recommended) — Sow 4-5 weeks before the last frost, 2-3 seeds 6" apart, 1/4- 1/2" deep. Darkness is required for germination. Thin to 6" apart when true leaves appear. Transplant — Sow 4-6 weeks before planting out. Sow into cell packs, 2 seeds directly into each cell or 3-4" container, 1/4- 1/2" deep. Keep soil surface moist until emergence. Thin to one plant when the true leaves appear. Transplant outside as soon as the soil can be worked. Seedlings won't be damaged by a late frost.
