Care Guide

Watering

Water deeply every 1–2 weeks for young trees; mature trees only need supplemental water during prolonged drought

Fertilization

Light application of slow-release, low-nitrogen fertilizer in early spring. Over-fertilization can cause excessive foliage growth and reduce drought tolerance

Eggshell powder topdress:Crush clean, dried eggshells into fine powder; topdress 1–2 cups around the tree base every 6 months to improve soil drainage and add calcium
Pruning
  • Remove dead, damaged, or diseased branches in late winter before new growth emerges
  • Thin overcrowded inner branches to improve air circulation and reduce pest risk
  • Avoid heavy pruning, as conifers do not regrow foliage from old, woody stems
