- Fertilization Time: Fertilize in early spring to support new growth.
- Fertilizer Type: Use a balanced, slow-release fertilizer or an acidic fertilizer suited for evergreens.
|
Additional Care Tips
|
- Mulching: Apply a 2-3 inch layer of mulch around the base to retain moisture, suppress weeds, and regulate soil temperature. Keep mulch away from the crown to prevent rot.
- Drought Tolerance: Once established, Blue Star is highly drought-tolerant, making it ideal for low-water gardens and xeriscaping.
- Pests and Diseases: Generally pest-free, though spider mites or fungal diseases may occasionally appear if grown in overly wet or humid conditions. Ensure good air circulation and proper drainage to prevent issues.
