• Soil Preparation: Select a sunny location with moderately moist, well-drained soil.
• Sowing: Start indoors 6–8 weeks before the last frost, or sow directly outdoors after frost risk passes.
• Depth: Press seeds lightly into the soil surface; do not cover deeply, as they require light for germination.
• Watering: Keep soil lightly moist during germination (14–21 days).
• Transplanting: Move seedlings outdoors when they reach 2–3 inches tall, spacing them 18–24 inches apart.
• Care: Water regularly until plants are established, then reduce frequency.
• Maintenance: Deadhead spent blooms to encourage prolonged flowering. Prune lightly in early spring to shape the plant.
