Care Guide

Watering

Water every 7–10 days during extended dry spells; reduce during regular rainfall

Fertilization

Apply slow-release, low-nitrogen fertilizer once in early spring. Avoid high-nitrogen fertilizers to prevent excessive foliage growth at the expense of cone production

Eggshell powder topdressing:Crush clean, dried eggshells into fine powder; sprinkle lightly on soil surface and gently work in to avoid disturbing shallow roots
Pruning
  • Remove dead or damaged branches in late winter to improve air circulation
  • Thin crowded inner branches to allow sunlight penetration for healthy foliage
  • Avoid heavy pruning; maintain the tree's natural compact crown shape
