Care Guide
Keep soil consistently moist; increase watering frequency during prolonged hot, dry spells
Apply balanced slow-release fertilizer once at bud break. Do not over-fertilize, as this can lead to weak, brittle branches prone to breakage
Eggshell powder topdress：Crush fully dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base and water in to release calcium gradually- Remove dead, damaged, or crossing branches in late winter to improve airflow and reduce disease risk
- Trim overgrown pendulous branches to maintain desired canopy shape and prevent branch breakage
- Thin dense inner growth to allow sunlight penetration to lower branches
- Avoid heavy pruning during active growing season to minimize sap loss and stress
