Short answer
Rubber plants typically shed leaves due to sudden environmental changes or inconsistent soil moisture levels. The most common fix is to ensure the plant is placed away from drafts or heating vents and to strictly adhere to a watering schedule that allows the top two inches of soil to dry out completely.
Seeing your Ficus elastica drop leaves can be alarming, but it is often the plant's way of signaling a protest against a sudden change in its environment. While some lower leaf drop is a natural part of aging, rapid or extensive shedding usually indicates stress that needs prompt attention to avoid long-term decline.
Ficus elastica are sensitive to 'wet feet' and will drop leaves if the soil remains soggy for too long. Conversely, severe drought can cause the plant to drop older leaves to conserve moisture for the stems.
Check: Check the soil moisture two inches deep; if it feels mucky or water pools in the saucer, overwatering is the culprit.
Fix: Adjust your watering schedule to wait until the top two inches of soil are dry, and ensure the pot has adequate drainage holes.
Rubber plants thrive in stable temperatures and react poorly to sudden cold drafts or direct heat from vents. Even a minor temperature swing near a window or doorway can trigger a stress response that leads to immediate leaf drop.
Check: Look for leaf drop occurring specifically on the side of the plant closest to an air conditioning vent, heater, or a drafty window.
Fix: Relocate the plant to a spot with stable, indirect light away from any forced air sources or frequent traffic areas.
If the plant is not receiving sufficient bright, indirect light, it will struggle to photosynthesize, eventually dropping lower leaves that are no longer productive. Dust buildup on the large, waxy leaves exacerbates this by physically blocking available light.
Check: Inspect the leaves for a thick layer of dust and observe if the stems are reaching or 'stretching' toward the nearest light source.
Fix: Move the plant to a brighter location and gently wipe the leaves with a damp cloth every few weeks to maximize light absorption.
When to worry
You should take urgent action if you notice significant leaf drop over a single week or if the remaining leaves show yellowing, black spots, or mushy textures, as this often indicates root rot.

Unfortunately, no. Once a leaf drops on a Ficus elastica, that specific spot on the stem will remain bare, which is why proper placement is essential to maintain the plant's shape.
The milky latex sap can be a skin irritant to some people and is toxic if ingested by pets, so handle the plant with care and wash your hands after pruning.
