2. Watering:

- Maintain medium moisture levels with regular watering.

- Water deeply once weekly, providing approximately 1 inch of water.

- Increase watering during hot, dry periods and when newly planted.

- Avoid overhead watering to prevent powdery mildew development.

3. Soil Type:

- Thrives in rich, well-draining soil with moderate moisture retention.

- Tolerates a range of soil types including clay if drainage is improved.

- Amend heavy soils with compost to enhance drainage and fertility.

- Maintain a layer of mulch to preserve soil moisture and suppress weeds.

4. Temperature & Hardiness Zone:

5. Fertilizer:

- Apply a balanced, slow-release fertilizer in early spring as new growth emerges.

- Side-dress with compost once annually in spring to improve soil structure.

- Avoid high-nitrogen fertilizers which can promote excessive foliage growth and reduce flowering.

- Reduce fertilization in poor-draining soils to prevent root rot issues.

6. Pruning & Maintenance:

- Deadhead spent blooms to encourage additional flowering and prevent self-seeding.

- Cut back stems to about 2 inches above soil level in late fall or early spring.

- Divide plants every 2-3 years in spring to maintain vigor and prevent center die-out.

- Thin stems in early summer if plants become crowded to improve air circulation.
