- Planting Location: Choose a sunny location with well-draining soil. Cosmos thrives in full sun but can tolerate some light shade.
- Soil Preparation: These plants prefer moderately fertile soil that drains well. Adding organic compost can improve soil quality and ensure healthy growth.
- Watering: Water regularly, especially during dry periods. Allow the soil to dry slightly between waterings as Cosmos are somewhat drought-tolerant once established.
- Maintenance: Deadheading spent flowers will encourage more blooms, and trimming back tall stems can promote bushier growth and prevent leggy plants.
