Care Guide

Watering

Water once every 2–3 weeks if no natural rainfall

Fertilization

Diluted low-nitrogen feed once every 2 months. Fertilize only if soil is severely nutrient-deficient; avoid high-nitrogen products

Eggshell powder top-dressing:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base; work lightly into topsoil to boost soil calcium levels without over-fertilizing
Pruning
  • Remove dead or damaged branches in late winter to maintain canopy shape and airflow
  • Thin overcrowded inner branches to improve light penetration to lower foliage
  • Avoid heavy pruning, as the tree has a slow growth rate and recovers slowly
