Care Guide

Watering

Water deeply every 7–10 days during dry periods to support new growth

Fertilization

Apply balanced slow-release fertilizer once at bud break. Use fertilizer with equal nitrogen, phosphorus, and potassium to support healthy foliage growth

Eggshell powder topdressing:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base and water in to release nutrients gradually
Pruning
  • Remove dead, damaged, or crossing branches in late winter before new growth emerges
  • Thin crowded inner branches to improve airflow and light penetration
  • Shape lightly to maintain a natural rounded canopy; avoid heavy pruning that can weaken the tree
  • Remove low suckers from the base to direct energy to the main trunk
