Caring for White Coneflower
Watering
- Water regularly during the first growing season to establish a strong root system.
- Once established, white coneflowers are drought-tolerant. Water only during prolonged dry spells.
Fertilizing
- A balanced, slow-release fertilizer in early spring can encourage robust growth.
- Avoid over-fertilizing, as this can lead to leggy plants.
Pruning and Deadheading
- Deadhead spent blooms to encourage more flowering and to keep the plant looking tidy.
- In late fall, cut back the plants to about 3 to 4 inches above the ground.
Pest and Disease Management
- White coneflowers are generally resistant to pests and diseases but can be susceptible to powdery mildew in humid conditions. Ensure good air circulation and avoid overhead watering.

- Plant in Groups: Mass plantings attract more pollinators than solitary plants.
