China Doll Plant White Mold: Overwatering in AC Office

Your office China Doll (Radermachera sinica) has white mold on leaves/stems and drops leaves after 3 months in AC with regular watering.

Cause

Overwatering in cool conditions. AC slows growth → less water used. Soil stays wet → mold + root rot.

Fix

1. Spray lightly with Lysol to kill mold.
2. Move to sunny window on weekends.
3. Water ONLY when soil surface dry 4–5 days AND pot feels light.
4. Use bamboo skewer: water only when lower 2 inches moist.
5. Empty drain tray 1 hour after watering.

China Dolls hate wet feet, especially in AC.
