Care Guide
Placement
Full sun to partial shade
May bronze in winter sun - some shade helps.
Watering
Moderate
Needs humidity; avoid letting roots dry.
Fertilization
Balanced
Light feed due to slow metabolism.
Pruning
Structural in spring, maintenance summer
Trim candles and pinch new tips mid-summer.
Wiring
Spring or Autumn
Use aluminum wire; bark is thin and sensitive.
Repotting
Every 2-3 years
Handle gently; roots are fragile when dry.
Propagation
Cuttings or seed
Semi-hardwood cuttings in late summer root best.
Winter: Foliage may brown slightly; normal for species.
Summer: Requires frequent misting in hot, dry weather.
Zone 8b: Avoid repotting in wet winter
