Why Are Your Aglaonemas Plant Leaves Turning Yellow:
Causes and Solutions

Aglaonemas, also known as Chinese Evergreens, are popular houseplants due to their attractive foliage and ease of care. However, if you notice that your Aglaonema’s leaves are turning yellow, it could be a sign of an underlying issue. In this article, we will discuss the possible causes of yellowing leaves in Aglaonemas and provide solutions to help restore their health.

Causes of Yellowing Leaves in Aglaonemas

Overwatering

Overwatering is one of the most common causes of yellowing leaves in Aglaonemas. Aglaonemas prefer well-draining soil, and if they are left sitting in waterlogged soil for too long, their roots can suffocate and rot. This can lead to a lack of oxygen and vital nutrients reaching the plant’s leaves, causing them to turn yellow.

Solution: Allow the soil to dry out slightly between watering sessions. Ensure that the pot has drainage holes to prevent waterlogging. When watering, ensure that the water drains freely from the drainage holes.

Underwatering

Underwatering can also cause yellowing leaves in Aglaonemas. If your plant is not receiving enough water, its leaves may start to wilt and turn yellow as a sign of distress.

Solution: Water your Aglaonema thoroughly when the top inch of soil feels dry to the touch. Ensure that the pot has drainage holes to prevent waterlogging.

Low Humidity

Aglaonemas prefer a humid environment, and low humidity levels can cause their leaves to turn yellow or brown at the tips.

Solution: Increase humidity levels by placing a tray of water near your plant, using a humidifier or grouping your plants together. You can also mist your plant regularly with a spray bottle filled with clean water.

Pest Infestation

Pests such as spider mites or mealybugs can infest Aglaonemas, causing yellowing leaves as they suck the sap out of them.

Solution: Inspect your plant regularly for any signs of pests. If you spot any, isolate your plant and treat it immediately with an insecticidal soap or neem oil.

Disease

Aglaonemas can be prone to several diseases such as root rot, bacterial leaf spot or fungal leaf spot. These diseases can cause yellowing leaves or black spots on the foliage.

Solution: Remove any affected leaves immediately and isolate your plant to prevent further spread. Ensure that your plant is not overwatered and avoid getting water on its leaves.

FAQs

A: Yes, you can remove yellow leaves from your Aglaonema to improve its appearance and prevent any disease from spreading. However, ensure that you use clean, sharp scissors or pruning shears to avoid damaging the healthy foliage.

Q: How often should I fertilize my Aglaonema?

A: You can fertilize your Aglaonema once a month during its growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.

Q: Can I propagate my Aglaonema from cuttings?

In conclusion, yellowing leaves in Aglaonemas can be caused by various factors such as overwatering, underwatering, low humidity levels, pest infestations or diseases. By identifying the cause and taking appropriate measures, you can restore your plant’s health and beauty. Remember to always inspect your plants regularly for any signs of distress, and take action promptly to prevent any issues from worsening.
