Allow 7–21 days at 70–75°F (21–24°C).

SOWING:

For transplants, start seed 5–6 weeks before planting out and cover it only barely. Water from below or with a mist so the seed stays near the surface. Move seedlings into cell packs or bigger containers once the second set of true leaves forms, harden them off, and plant outdoors after frost danger has passed. To sow in place, wait until after the last frost, cover the seed thinly, keep the bed moist, and thin to the spacing you want. Sow in rows rather than broadcasting.
