Why Is Your Rubber Tree Losing Leaves? Common Causes and Solutions

Why Rubber Tree Leaves Drop

If your rubber plant (Ficus elastica) is shedding leaves, it's usually a sign of environmental stress. While alarming, leaf drop is often reversible once you identify the trigger. Here are the most common reasons and how to fix them.

Sudden Light Changes

Moving a rubber tree from outdoors to indoors—or even shifting it to a lower-light spot—can cause massive leaf loss. The plant needs time to acclimate. Gradually transition it over 1–2 weeks, and supplement with grow lights if indoor light is weak.

Pest Infestations

Scale insects are a frequent culprit. These tiny, immobile pests attach to stems and leaves, sucking sap and causing yellowing and drop. Treat with neem oil or insecticidal soap, repeating weekly until gone.

Low Humidity

Rubber trees thrive in 40–50% humidity. Winter heating dries indoor air, leading to crispy, falling leaves. Mist daily, use a pebble tray, or run a humidifier nearby.

Cold Drafts

Even if the room is warm, drafts from windows, doors, or AC vents can shock the plant. Relocate it away from airflow paths.

Over-Fertilization

Too much fertilizer burns roots and forces leaf drop. Feed only once every 2–3 months during spring and summer with a diluted balanced fertilizer.

Overwatering

Soggy soil suffocates roots, causing leaves to yellow and fall. Water only when the top 2 inches of soil are dry. Ensure the pot has drainage holes.
