Monstera plants, known for their striking split leaves, are a favorite among indoor plant enthusiasts. However, brown leaves can be a sign of distress. Identifying the cause is crucial to restoring your Monstera's health. Here are the most common reasons for browning leaves and how to address them.

1. Underwatering

One of the most common causes of brown leaf edges is underwatering. When a Monstera doesn’t get enough moisture, its leaves lose hydration, leading to dry, crispy brown edges.
Solution: Check the soil moisture regularly. Water the plant when the top 2 inches of soil feel dry, ensuring the entire root system is hydrated.

2. Overwatering

Overwatering can lead to root rot, causing brown or black spots on the leaves. Monstera roots need oxygen, and waterlogged soil deprives them of it.
Solution: Allow the soil to dry out between waterings. Ensure your pot has drainage holes to prevent standing water.

3. Low Humidity

Monstera plants thrive in tropical environments with high humidity. In dry indoor conditions, the leaf tips can turn brown.
Solution: Increase humidity by using a humidifier, misting the leaves, or placing a water tray near the plant.

4. Direct Sunlight

Excessive direct sunlight can scorch Monstera leaves, causing them to turn brown or yellow.
Solution: Place your plant in bright, indirect light. Avoid exposing it to harsh afternoon sun.

5. Nutrient Deficiency

A lack of essential nutrients, such as nitrogen or potassium, can result in browning leaves.
Solution: Feed your Monstera with a balanced liquid fertilizer during the growing season to support healthy foliage.

6. Pests or Diseases

Insects like spider mites or fungal infections can damage leaves, leading to brown spots.
Solution: Inspect your plant regularly and treat infestations with neem oil or insecticidal soap.

Final Tips

Address browning leaves promptly by diagnosing the issue and adjusting your care routine. With proper watering, humidity, and lighting, your Monstera will thrive, keeping its leaves lush and green.
