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

Updated: May 19, 2023

Aloe plants are popular houseplants due to their ability to purify the air and their medicinal properties. However, they are also prone to certain issues, such as yellowing leaves. Yellowing leaves can be a sign of various problems, ranging from overwatering to pests. In this article, we will explore the possible causes of yellowing leaves in aloe plants and provide solutions to prevent further damage.

Causes of Yellowing Leaves in Aloe Plants

Overwatering

One of the most common causes of yellowing leaves in aloe plants is overwatering. Aloe plants are succulents that store water in their leaves, stems, and roots. They thrive in dry conditions and do not require frequent watering.

When an aloe plant is overwatered, its roots become waterlogged and unable to absorb oxygen. This leads to root rot, which can cause the plant’s leaves to turn yellow and mushy.

Underwatering

On the other hand, underwatering can also lead to yellowing leaves in aloe plants. When an aloe plant does not receive enough water, its leaves will start to wilt and turn yellow.

Lack of Sunlight

Aloe plants require bright, indirect sunlight to grow properly. When an aloe plant does not receive enough sunlight, its leaves will turn yellow or brown.

Pests

Pests such as spider mites, mealybugs, and scale insects can infest aloe plants and cause their leaves to turn yellow. These pests suck the sap out of the plant’s leaves, causing them to wither and yellow.

Solutions for Yellowing Leaves in Aloe Plants

Adjust Watering Frequency

To prevent overwatering or underwatering your aloe plant, it’s essential to adjust your watering frequency. A general rule of thumb is to water your aloe plant once every two weeks during the summer months and once every four weeks during the winter months.

It’s important to ensure that the soil is completely dry before watering your aloe plant again. You can check this by sticking your finger into the soil up to your knuckle; if it feels dry, it’s time to water your plant.

Increase Sunlight Exposure

If your aloe plant is not receiving enough sunlight, you can move it closer to a window or place it outside for a few hours each day. However, be careful not to expose it to direct sunlight as this can burn its leaves.

Pest Control

If you suspect that your aloe plant has pests, you can use insecticidal soap or neem oil to control them. These products are safe for use on aloe plants and can effectively kill pests without harming the plant.

Frequently Asked Questions (FAQs)

Q: Can I save my aloe plant if its leaves have turned completely yellow?

A: If all of the leaves on your aloe plant have turned completely yellow and mushy, it may be too late to save it. However, you can try cutting off the healthy parts of the plant and propagating them into new plants.

Q: How do I propagate my aloe plant?

A: To propagate your aloe plant, cut off one or more of its healthy leaves near the base using a sharp knife. Allow the cut end to dry for a day or two before planting it in well-draining soil. Water sparingly until new growth appears.

Q: Can I use tap water to water my aloe plant?

A: Tap water contains minerals that can build up in the soil over time and harm your aloe plant. It’s best to use distilled or filtered water when watering your plant.

In conclusion, yellowing leaves in aloe plants can be caused by various factors such as overwatering, underwatering, lack of sunlight, and pests. By adjusting your watering frequency, increasing sunlight exposure, and using pest control methods when necessary, you can prevent further damage and keep your aloe plant healthy and thriving.
