Overwatering stress
Constantly wet soil with leaves dropping is overwatering, the most common cause of sudden leaf loss.
Diagnosis
Overwatering stress
What's happening
When a rubber plant's roots stay waterlogged they can't take up oxygen and begin to rot, which cuts off the water and nutrients the leaves need. The plant responds by dropping leaves quickly, often green ones, and the soil stays heavy and wet long after watering.
How to fix it
Stop watering and let the soil dry out well. Unpot the plant and check the roots — trim any brown, mushy ones with clean scissors and repot into fresh, fast-draining mix in a pot with drainage holes. Always tip out the saucer afterward, and from now on only water once the top 1–2 inches are dry so the roots can breathe between drinks.
What fixes it
- Pots with drainage holes — Repotting into a pot with real drainage stops water pooling and re-rotting the roots.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
