In this blog post, I will give you 7 reasons why your Monstera leaves are turning yellow. I hope this knowledge helps put some of those worries at ease!
7 Reasons Your Monstera Leaves Are Turning Yellow
1. Watering Issues
This one is pretty straightforward. Improper watering is the primary common reason for yellow monstera leaves. Proper watering is a significant step in any plant care, including your favorite Monstera Deliciosa. When you notice monstera leaves turning yellow, always check the soil moisture and, worst-case scenario, root rot.
Too much soil moisture, caused by overwatering, stresses your plant. Monstera does not do well in prolonged wet soil. The excess water will lead to rotting of the roots, yellowing the leaves, and eventually, death of the plant. Always ensure that the soil remains damp and not completely wet by watering your plant only when the top 2-3 inches of soil are dry. Drainage holes in the bottom of the pot may be useful if you are a new plant parent or worried about root rot.
The yellow monstera plant leaves can also be a result of underwatering. If there is no enough moisture in the soil, the plant fails to accumulate sufficient nutrients needed for photosynthesis. As a result, the leaves lack chlorophyll, making them turn yellow. You may also find some yellow and brown spots on the leaves.
2. Improper Lighting
If your home’s lighting is poor, this might be another common reason why your Monstera leaves are turning yellow. The monstera plant is native to America’s tropical regions with low to bright indirect sunlight. The monstera leaves can quickly burn if exposed to much direct sunlight for an extended period. On the other hand, too much light exposure may also scorch the plant leading to yellow leaves.
On the other hand, lack of sunlight will lead to slow growth and cause the Swiss Cheese Plant leaves to turn yellow. Avoid such issues by moving your plant accordingly. Preferably, please place it in an area it can receive a few hours of bright morning sunlight or use magic mirrors to reflect light into the room. During the winter months, I supplement all of my plants with a grow light.
3. Pests and Disease
Unfortunately, pests can be a common problem for plant owners. Like any other plant, the Monstera plant can also be attacked by pests and disease, causing its leaves to turn yellow. Sap-sucking insects like spider mites, mealybugs, and aphids feed on the plant, causing the monstera leaves to turn yellow. The yellow leaves and fronds form because the insects drain moisture off your plant.
If you have pests, you will need to pay close attention to your Monstera’s leaves. Monitor your plant constantly and address any signs of pest or disease infection. One way of doing so is by spraying the affected plant or part of the plant with soap and water solution, insecticidal soap, rubbing alcohol, neem oil, or any other recommended pesticides from your local nursery.
Common monstera diseases include anthracnose, fungal leaf spots, and powdery mildew. You should also spray the infected parts or remove the infected leaves.
4. Humidity and Temperature
The temperature or humidity level in your home may not be warm enough for this type of houseplant. Monsteras are tropical plants, so low humidity, and hot temperatures can also cause Monstera leaves yellowing. Low humidity causes browning of the edges of the leaves, and eventually, the entire leaf turns yellow. To increase the plant’s humidity, regularly mist the leaves with water or place a water-filled tray with stones beneath the plant’s pot.
Similarly, extreme temperatures or sudden temperature changes cause leaves to drop and your monstera leaves to yellow. Place your plant in a warm spot or an ideal spot with tropical temperatures, preferably 65-80° F (18-27°C.) You will always want to place your plant away from any cold drafts and dry heat vents.
5. Transplant Stress
If you’ve just repotted your Monstera plant and its leaves start turning yellow, this might be caused by transplant stress. Such stress might be because of transplanting at the wrong time of the year, moving the plant to a different soil type, root damage, wrong soil pH, any big temperature drops, exposing the roots for too long before re-planting, or moving it to a different location. Some plants can be susceptible to environmental changes.
As a result, the plant may require some time to recover and adapt to the new changes. Meanwhile, you can pamper the plant by ensuring it has enough drainage, enough water, putting it back to its earlier location, or removing the dead leaves.
6. Fungus Infection
Dark brown or black splotches with a yellow ring or “halo” indicate that your Monstera has fungus. If a plant stays wet for a long time, then fungus can grow. Sometimes, a new plant will have these dark brown spots if it wasn’t given quality care while at the store or greenhouse. Therefore, you will want to remove all brown Monstera deliciosa leaves and make sure the remaining leaves stay dry. You will also want to cut off the affected stems to prevent spreading.
7. Natural Monstera Leaves Yellowing
Not all monstera leaf yellowing should concern you. Some monstera leaves just turn yellow naturally due to old age. When the plant is pushing out new growth and new leaves, yellow monstera leaves will start to form at the bottom of the plant. The plant is naturally shedding off the old leaves while focusing its energy on new growth. In this case, you don’t have to worry about your monstera’s older leaves turning yellow, especially during the growing season.
