China Doll (Radermachera) Sudden Leaf Drop: The Finicky Plant Syndrome

Your China doll in a large kitchen window losing leaves despite good light and "proper" watering is exhibiting classic Radermachera drama. These plants drop foliage for any stress: light change, watering inconsistency, temperature shift, drafts, pests, aging, or repotting.

Critical Requirements

• Light: Bright indirect (north/east window). Not "large window" generally.
• Stability: Never move once placed.
• Water: Top half-inch dry between thorough waterings.
• Temperature: 65–75°F constant. No drafts.
• Potbound: Do not repot. They prefer tight roots.

Management Strategy

• Prune regularly to maintain shape.
• Accept 1–2 year indoor lifespan.
• If recently repotted, that's the trigger.

Consistency is the only "cure." Even then, they're temporary guests.
