Plant Needs
Sunlight
Full sun to partial shade; tolerates coastal salt spray but benefits from partial shade in hot inland regions
Watering
Water deeply but infrequently; allow top 15–20 cm of soil to dry completely between waterings to prevent root rot

Care Guide
Watering
Water deeply every 7–10 days during dry spells
Fertilization
Diluted acid-loving plant fertilizer once monthly. Avoid over-fertilizing, as mature trees have low nutrient requirements
Eggshell powder topdress：Crush fully dried eggshells into fine powder; sprinkle lightly around the tree base to add calcium without altering soil pH excessivelyPruning
- Remove dead, damaged, or diseased branches in late winter to improve air circulation
- Thin crowded inner branches to increase light penetration for lower foliage
- Avoid heavy pruning, as mature trees recover slowly from major structural cuts
