Care Guide
Watering
Water regularly during establishment; reduce watering once mature to avoid root rot
Fertilization
Apply balanced slow-release fertilizer once in early spring. Do not over-fertilize, as this can reduce berry production
Eggshell powder top dressing：Crush dried eggshells into fine powder; sprinkle 1 tbsp per plant in early spring to boost soil calcium levelsPruning
- Prune immediately after flowering to shape hedges and remove dead, diseased, or crossing branches
- Thin dense inner growth to improve airflow and light penetration for better berry development
- Wear thick gloves to avoid injury from sharp spines; remove suckers to maintain desired plant form
