Why Is Your Aloe Vera Plant Turning Yellow and Brown?

Aloe vera is an incredibly versatile plant that is renowned for its healing properties. Its popularity has grown significantly in recent years, and many people now grow it in their homes as a decorative plant or for its medicinal benefits. However, even with the best intentions, your aloe vera plant can start to look unwell, with leaves turning yellow and brown, which can be a cause for concern. In this article, we will explore the reasons why your aloe vera plant may be turning yellow and brown, and what you can do to remedy the situation.

How Do Healthy Aloe Vera Plants Look?

Before we explore the reasons why your aloe vera plant may be turning yellow and brown, it is important to understand what a healthy aloe vera plant looks like. Healthy aloe vera plants have vibrant green leaves that are grey-green or blue-green in colour, depending on the variety. They have a circular rosette form and are lush and firm to the touch. When grown outdoors, they will produce clusters of dangling tubular yellow or orange flowers on long stalks in early spring. However, when grown indoors as houseplants, they tend not to flower.

The Symptoms of an Unhealthy Aloe Vera Plant

When aloe vera plants are subjected to unfavourable conditions, they may start to exhibit certain signs, including:

- Leaves become pale in colour, the green colour fades to a straw yellow colour which eventually turns light brown.
- Leaf tips darken and dry out.
- Leaves dry out and wither.
- Leaves become soft and mushy, and begin to rot.

How to Treat an Unhealthy Aloe Vera Plant

If your Aloe vera plant is showing signs of stress or disease, don’t worry, you can still save it. Here are some steps you can take to treat an unhealthy Aloe vera plant:

1. Identify the Problem - It's essential to identify the root cause of the problem before taking any action. Review the symptoms and identify the cause of the problem. Is it overwatering, underwatering, lack of nutrients, pests, or disease?

2. Adjust the Environment - Once you have identified the problem, make necessary changes to the environment. For example, if the problem is overwatering, reduce watering frequency and improve soil drainage. If the issue is pests, apply an insecticide or natural remedies to eliminate them.

3. Remove Dead and Diseased Tissues - Use a pair of clean, sharp scissors or pruning shears to remove the dead, yellow or brown leaves and any other diseased tissues. This will allow the plant to focus its energy on healthy growth.

4. Provide Adequate Nutrients - Aloe vera plants need a balanced diet of nutrients to thrive. You can feed your plant with a balanced fertilizer every two weeks during the growing season (spring and summer). Be sure to follow the manufacturer's instructions to avoid over-fertilizing, which can damage the plant.

5. Repot the Plant - If your Aloe vera plant is overgrown, repot it into a larger container with a well-draining potting mix. Make sure not to over-pot the plant, as this can lead to overwatering and root rot.


In summary, Aloe vera is a hardy and versatile plant that can thrive in a range of conditions. However, when subjected to unfavorable conditions, it can become stressed and show signs of disease. To prevent your Aloe vera plant from turning yellow and brown, you must provide the right growing conditions and take prompt action when signs of stress or disease appear. With the right care, your Aloe vera plant will continue to thrive and provide you with its many benefits for years to come.
