Planting Guide

1. Seed Stratification: For better germination, cold stratify seeds for 60–90 days in moist sand inside a refrigerator.

2. Sowing: After stratification, sow seeds ¼ inch deep in pots or directly outdoors in early spring.

3. Light Requirement: Choose a sunny to partly shaded area.

4. Watering: Keep soil evenly moist but not waterlogged.

5. Spacing: Space plants 3–5 feet apart for best air circulation.

6. Transplanting: Move seedlings once they are 3–5 inches tall.

7. Care: Mulch around the base to retain soil moisture and reduce weeds.

8. Maintenance: Prune lightly after flowering to shape the shrub.
