Care Guide
Watering
Water young trees weekly to maintain moist root zones; mature trees only during severe droughts
Fertilization
Apply slow-release acidic fertilizer once in early spring to support new growth. Avoid over-fertilizing, as excessive nutrients can damage root systems
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of young trees and gently work into topsoilPruning
- Remove dead, damaged, or diseased branches in late winter before new growth emerges
- Avoid heavy pruning; maintain the tree's natural narrow pyramidal form
- Thin crowded lower branches to improve airflow and reduce pest risk
