Maintenance Tips
- Drought-tolerant once established; water regularly during the first growing season and during prolonged dry periods thereafter.
- Deadhead spent blooms to encourage additional flowering and prevent self-seeding, if desired.
- Prefers well-drained soils and is tolerant of a range of soil types, including clay, if drainage is adequate.
- Apply a light layer of organic mulch to conserve moisture, suppress weeds, and maintain a clean appearance around the plant base.
- Monitor for pests such as aphids and diseases like powdery mildew, especially in humid conditions. Provide good air circulation and avoid overhead watering to minimize disease risks.
