Start seeds indoors 6 to 8 weeks before your average last frost date at a temperature of 65 to 75 degrees Fahrenheit, though cooler soil near 55 degrees produces better germination. Transplant seedlings outdoors 6 to 8 weeks before your average last frost date once they've developed true leaves and hardened off gradually to outdoor conditions.
Transplant hardened-off seedlings into the garden 6 to 8 weeks before your average last frost date. Space plants 18 inches apart with rows 24 inches apart. Ensure soil drains well to prevent waterlogging.
Sow seeds directly in the garden 6 to 8 weeks before your average last frost date in spring, or in late fall. Press seeds into the soil surface without covering.
