• Planting Time: Best in spring or fall
• Sun Requirements: Part shade to filtered sun (morning sun, afternoon shade)
• Soil Requirements: Acidic, rich, organic, well-drained soil - does not tolerate alkaline or compacted soils
• Moisture Needs: Keep soil evenly moist - use the Finger Test. New shrubs need consistent water during their first year
• Mulch: Always apply a 3-4 inch deep layer of Arborist Mulch to regulate temperature and conserve moisture
• Fertilization Needs: Use a fertilizer for acid-loving plants in spring after flowering; compost works well too
• Pruning Info: Minimal pruning needed - prune right after bloom if shaping is necessary. Avoid cutting late, as it forms buds on old wood.
• Special Perks: Deer-resistant, low-maintenance once established, excellent cold and heat tolerance for its range
• Provide winter watering for broadleaf evergreens to prevent winter burn. Read how and why here!
