Plant Needs
Sunlight
Full sun preferred for healthy cone production; tolerates partial shade in hot, dry mountain climates
Watering
Young trees need regular deep watering; mature trees are drought-tolerant, only water during extended dry spells
Temperature
Hardy to -20°C; adapts to hot, dry mountain summers and cold winter conditions

Care Guide
Watering
Young trees: water deeply every 7–10 days; mature trees: minimal supplemental watering
Fertilization
Slow-release granular fertilizer applied once in early spring. Avoid high-nitrogen fertilizers which can promote weak, susceptible growth
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle lightly around the base of young trees to improve soil structure and calcium levelsPruning
- Remove dead, damaged branches in late winter to improve air circulation
- Thin crowded lower branches to encourage strong, upright growth in young trees
- Avoid heavy pruning; preserve the natural twisted crown shape of mature specimens
