Summer/fall bloomFrost tender
Plant in full sun in good garden soil when weather is warm and settled both day and night and all danger of frost is past. Poke seeds into well-worked soil about 1 inch deep, 6 inches apart. Press soil firmly over seeds and keep moist as seedlings emerge.
Several weeks before last frost date, sow seeds 1 inch deep in individual pots of well drained seed starting mix. Keep moist and provide a strong light source until seedlings are ready to plant outside. Transplant carefully, disturbing the roots as little as possible.
When seedlings are about 3 inches tall, space them 12 – 18 inches apart with 3 feet between rows so these tall plants will have ample room to grow.
