Dendrobium Chrysotoxum Care: Leaf Loss, Light & Seasonal Rhythm

Leaf drop on older canes is normal for Dendrobium chrysotoxum. Fat pseudobulbs = healthy. Focus on mimicking its natural cycle.

Growing Conditions

Pot: Wooden slat basket—roots love air exposure.
Rest period (winter): Water only to prevent pseudobulb shriveling. No fertilizer.
Active growth (spring): Heavy watering + feeding. Bright light, humidity, cooler temps.
Summer: Hang outdoors in semi-shade (some direct sun OK). Pseudobulbs should be straw-colored; green = more light needed.

Your outdoor setup sounds right. Just respect the rest/growth cycle and don't overwater in winter.
