Growing Directions

• When to plant: Sow outdoors after the danger of frost has passed and the soil has warmed, or start indoors several weeks earlier for a jump on the season.
• Sunlight: Choose full sun for the strongest stems and best flowering.
• Soil: Plant in well-drained soil. Avoid overly rich fertility, which can encourage foliage at the expense of flowers.
• Sowing depth: Cover seeds lightly, about ¼ inch deep, and keep the seedbed evenly moist until seedlings are established.
• Spacing: Thin or transplant plants about 10–18 inches apart to allow airflow and room for the compact plants to branch.
• Watering: Water regularly while seedlings establish, then provide moderate moisture. Avoid constantly wet soil.
• Support: Dwarf plants usually need little support, but a low stake or small ring can help in windy locations.
• Deadheading: Remove spent flowers to keep the planting tidy and encourage additional blooms. Leave a few flowers if you want seed to mature.
• Harvesting: Cut stems when flowers are newly open for the longest vase life, and place them in water promptly.
