What Causes Rubber Tree Leaves To Fall Off

Rubber trees are an attractive and common houseplant. They have thick, glossy leaves that add texture and color to any room. Unfortunately, sometimes the leaves can start to fall off. It can be concerning when this happens, but it’s important to know what may be causing it so you can try to remedy the situation.

In this article, we will explore some possible causes of rubber tree leaves falling off. There are a few things that could be causing your rubber tree leaves to drop off. Environmental issues such as too much or too little water or exposure to cold temperatures can all cause the leaves to turn yellow and fall off.

Fungal diseases like root rot and powdery mildew can also cause the leaves to become discolored and drop prematurely. Finally, pests like mealybugs or spider mites may also damage the plant enough for it to shed its leaves.

Environmental Issues

Rubber tree leaves falling off can be caused by a variety of environmental issues. Hot temperatures can cause the leaves to become dry and brittle, resulting in them falling off the tree. When this happens, it’s important to keep the plant in a cooler environment.

Additionally, insufficient light can lead to rubber tree leaves losing their luster and turning yellow or brown before eventually dropping from the tree. To prevent this from happening, it’s important to provide adequate lighting for your rubber tree and ensure that it has access to sunlight for at least several hours each day.

All in all, environmental issues can cause rubber tree leaves to fall off if not managed properly. Taking steps such as keeping the plant in a cool area and providing adequate sunlight can help prevent this issue from occurring.

Fungal Diseases

Environmental issues can often be the cause of rubber tree leaves falling off. In some cases, over fertilization can lead to a build up of salt in the soil, which will stunt growth and eventually cause leaves to fall off.

Insufficient light is another common cause of leaf drop for rubber trees. If the tree isn’t getting enough light, it won’t be able to produce enough energy to keep its foliage healthy, leading to yellowing and eventual leaf drop.

When this happens, it’s important to adjust the amount of fertilizer and move the tree closer to a source of light if possible. With proper care and attention, these issues can be minimized or avoided entirely.

Too Much Water

Excessive moisture levels are one of the main causes of rubber tree leaves falling off.

Climate change has caused increased rainfall in many areas, leading to higher levels of water than the trees are able to tolerate.

In addition, herbicides used to control weeds can cause damage to the root system and result in leaf loss from the tree.

This is because herbicides kill not only weeds but also beneficial soil organisms that help with nutrient uptake and water absorption by the trees.

Without these organisms, rubber trees become increasingly vulnerable to drought-like conditions and cannot take up enough water for healthy growth.

As a result, leaves will fall off due to dehydration or lack of nutrients.

Too Little Water

Rubber tree leaves falling off can be a sign of too little water. Without enough water, the plant cannot absorb nutrients from the soil and its leaves will begin to wither and drop off. To avoid this, it’s important to give your rubber tree regular watering during its active growing season.

Over fertilizing and incorrect lighting can also lead to leaf loss in rubber trees. Here are some tips for keeping your rubber tree healthy:

  • Check the soil before watering – if it is still moist, don’t add more water as it can cause root rot.

  • Use a balanced fertilizer such as 10-10-10 or 20-20-20 once per month during the spring and summer months.

  • Place your rubber tree near an east or west facing window so that it gets bright but indirect light throughout the day.

By following these guidelines, you can ensure that your rubber tree has access to all of the resources it needs to thrive and prevent its leaves from falling off due to lack of care.


The leaves of a rubber tree can fall off for many reasons, and pests are one of them. It’s essential to inspect the tree regularly, as pest infestations can have a devastating impact on the health of the tree.

Pests can cause the leaves to become discolored, misshapen, or to fall off completely. Other causes for leaf drop may include overfertilizing or improper pruning. Both of these practices can leave the tree vulnerable to pests and other environmental hazards.

Adopting proper care practices such as fertilizing correctly and avoiding drastic pruning will protect your rubber tree from suffering any ill effects from pests. Taking these steps will help ensure that your rubber tree remains healthy and vibrant for years to come.


The causes of rubber tree leaves falling off vary, but some environmental issues, fungal diseases, too much/little water, and pests can all contribute.

It’s important to identify the cause in order to know how to respond.

If it’s a fungal disease or pest, the best course of action is to use fungicide or insecticide.

If it’s an environmental issue, you may need to adjust the light levels or temperature.

And if it’s due to too much/little water, you’ll want to make sure you’re providing your rubber tree with the right amount of hydration.

I recommend consulting with a professional if you’re unsure about what’s causing your rubber tree’s leaves to fall off.
