Care Guide

Watering

Water young trees deeply once weekly; mature trees only during extended droughts

Fertilization

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

Eggshell powder topdressing:Crush dried eggshells into fine powder; sprinkle lightly around the tree base and water in to release calcium, supporting root and cone development
Pruning
  • Remove dead, damaged, or diseased branches in late winter to maintain canopy health and airflow
  • Thin crowded lower branches to improve light penetration and create a clear trunk if desired
  • Avoid heavy pruning, as conifers do not regrow from bare wood; only trim to shape or remove problematic growth
⚠️
