Sowing Depth: Sow shallowly, generally about one-eighth to one-quarter inch deep depending on seed size.

Spacing: Thin or transplant seedlings about eight to eighteen inches apart, adjusted for mature variety size.

Germination: Warm, steady conditions commonly support germination within about one to three weeks.
