Probable Causes of Swiss Cheese Plant Turning Yellow and Brown

Also known as the Monstera Deliciosa or split leaf philodendron, the Swiss cheese plant is a popular houseplant that is valued for its attractive foliage, air-purifying qualities, and easy-to-care features. However, when you notice that your Swiss cheese plant is turning yellow and brown, this is an indication of a problem.

Possible Reasons Your Swiss Cheese Plant is Turning Yellow and Brown

The following are the possible reasons why your Swiss cheese plant is turning yellow and brown:

Poor Watering Practice

If your Swiss cheese plant is not getting enough water or if it is getting too much water, the leaves may start to turn yellow and brown. When under-watered, the leaves will start to curl, and when over-watered, the leaves will turn yellow and droop. The plant may also develop root rot, which means the roots stop taking in water and nutrients, leading to yellowing and browning of leaves.

Low Light Conditions

Swiss cheese plants thrive in bright, indirect light. When exposed to low light conditions, the plant's leaves will start to turn yellow and eventually brown.

Pests and Diseases

The Swiss cheese plant is also vulnerable to pest infestation and diseases, which can manifest in yellowing and browning of leaves. Common pests that attack the Swiss cheese plant include spider mites, mealybugs, and scale insects. On the other hand, common Swiss cheese plant diseases include leaf spot, powdery mildew, and root rot.

How to Treat a Yellowed and Brown Swiss Cheese Plant

The following are the ways to treat a Swiss cheese plant that is turning yellow and brown:

Watering

To avoid over-watering or under-watering a Swiss cheese plant, be sure to water the plant only when the top one inch of soil is dry to the touch. You can also use a moisture meter to check the soil's moisture levels.

Light

Swiss cheese plants need bright, indirect light to thrive. Therefore, you should place your Swiss cheese plant in a bright room, close to a window that offers a lot of natural light. If your room doesn't have enough natural light, you can also use grow lights.

Pest and Disease Control

When dealing with pest infestation, you should remove the affected leaves and apply insecticidal soap or neem oil to control and prevent further infestation. For diseases, remove the infected parts of the plant and apply a fungicide.
