Monstera Leaves Turning Yellow, I Found 9 Reasons

Monstera plants are known for their lush, green leaves that can add a touch of tropical elegance to any room.

However, if you are noticing that your Monstera leaves are turning yellow, it can be a cause for concern. Yellow leaves can be a sign of a variety of issues, ranging from overwatering to inadequate light exposure.

In this article, we will explore the various reasons why Monstera leaves turn yellow and what you can do to fix the problem.

9 Reasons Why My Monstera Leaves Turning Yellow

1. Pests

One of the reasons why Monstera leaves turn yellow is due to pests. Pests such as spider mites can cause damage to the leaves of the plant, which can cause them to turn yellow.

If you suspect that your Monstera plant has pests, you should inspect the leaves and stems for any signs of infestation. You may also notice small webs or tiny insects crawling on the leaves.

To get rid of pests, you can use insecticidal soap or neem oil. Be sure to follow the instructions carefully to avoid damaging the plant.

2. Mold or Powdery Mildew

Another reason why Monstera leaves turn yellow is due to mold or powdery mildew. These fungal infections can develop if the plant is exposed to excessive moisture or if the air is too humid.

You may notice a white or grayish coating on the leaves and stems, which can cause them to turn yellow.

To prevent mold and powdery mildew, you should avoid overwatering the plant and ensure that the air circulation is good around the plant. You can also use a fungicide to treat the infection.

3. Root Bound

If your Monstera plant has been in the same pot for a long time, it may become root-bound.

This means that the roots have grown too big for the pot, which can cause the plant to become stressed. One of the signs of a root-bound plant is yellowing leaves.

To fix this problem, you can repot the plant into a larger pot with fresh soil. Be sure to gently loosen the roots before transplanting to avoid damaging them.

4. Overwatering

Overwatering is one of the most common reasons why Monstera leaves turn yellow. When the plant receives too much water, the roots can become waterlogged, which can cause them to rot.

This can lead to yellowing leaves and, eventually, the death of the plant.

To prevent overwatering, you should allow the top inch of soil to dry out before watering again. You can also use a well-draining potting mix and ensure that the pot has drainage holes.

5. Lack of Water

On the other hand, if your Monstera plant is not getting enough water, the leaves may also turn yellow. This is because the plant is not receiving enough nutrients from the soil.

To fix this problem, you should water the plant regularly, ensuring that the soil is moist but not waterlogged.

You can also mist the leaves with water to increase humidity around the plant.

6. Sun Exposure

Monstera plants require bright, indirect sunlight to thrive. If the plant is not receiving enough sunlight, the leaves may turn yellow.

On the other hand, if the plant is exposed to too much direct sunlight, the leaves may also turn yellow and develop brown spots.

To fix this problem, you should move the plant to a location with better lighting.

You can also use a sheer curtain to filter the sunlight or rotate the plant every few weeks to ensure that all sides receive equal amounts of light.

7. Fertilizer Root Burn

If you have been fertilizing your Monstera plant too much, it can cause fertilizer root burn.

This occurs when the fertilizer salts build up in the soil, which can cause the roots to burn and the leaves to turn yellow.

To fix this problem, you should flush the soil with water to remove the excess fertilizer salts.

You should also avoid fertilizing the plant too often and use a balanced fertilizer that is appropriate for Monstera plants.

8. Soil Type

Monstera plants require well-draining soil that is rich in organic matter. If the soil is too heavy or clay-like, it can cause the roots to become waterlogged, which can lead to yellowing leaves.

To fix this problem, you can repot the plant into a well-draining potting mix that is specifically designed for Monstera plants.

9. Sudden Change in Temperature

Monstera plants are sensitive to sudden changes in temperature. If the plant is exposed to extreme cold or hot temperatures, it can cause the leaves to turn yellow.

To prevent this problem, you should avoid placing the plant near drafty windows or doors.

You can also cover the plant with a cloth or blanket if the temperature drops suddenly.

Final Words

In summary, there are many reasons why Monstera leaves turn yellow, ranging from overwatering to inadequate light exposure.

By identifying the cause of the problem, you can take the necessary steps to fix it and ensure that your Monstera plant remains healthy and vibrant.

With proper care and attention, your Monstera plant can thrive and add a touch of tropical beauty to your home.
