Summer/fall bloomFrost tender
Sow seeds in a well-worked seedbed in full sun when danger of frost is past and weather is warm and settled. Space seeds 2 to 3 inches apart in rows 12 inches apart, cover about 1/2 inch deep and gently firm soil. Keep soil evenly moist while awaiting germination.
One month before last frost date, sow seeds 1/2 inch deep and 3 inches apart in a container of seed starting mix. Keep moist and provide a strong light source until seedlings are ready to plant out. Gradually acclimate to outdoor conditions before transplanting.
Space seedlings 10 to 12 inches apart to give plants room to mature.
