TO START OUTDOORS: In late spring once weather is warm and settled and nights stay above 50°F (10°C) plant seeds in a sunny spot in ordinary garden soil 2 to 3 inches apart and 1/2 inch deep. Firm soil over seeds.
TO START EARLY INDOORS: Sow indoors 4 or 5 weeks before last expected frost in individual pots of seed starting mix. Cover 1⁄2 inch deep and keep warm and moist. Provide a strong light source until seedlings are ready to plant outdoors. Transplant very carefully once nights stay above 50°F (10°C) and before seedlings get too crowded. Thin or transplant seedlings 6 to 8 inches apart. Avoid disturbing roots
