Care Guide
Watering
Water deeply once every 2–3 weeks during active growth; avoid overwatering
Fertilization
Diluted low-nitrogen feed once at bud break. Over-fertilization can cause excessive leaf growth at the expense of flowering
Eggshell powder topdressing：Crush thoroughly dried eggshells into fine powder; sprinkle 1–2 tablespoons around the tree base every 3 months; avoid direct trunk contact to prevent rotPruning
- Remove dead or damaged branches in late winter to maintain structural integrity
- Thin crowded inner branches to improve airflow and reduce pest risk
