Why is my Aloe Plant Turning Brown?

Is your aloe vera plant turning brown? Learn the common reasons for brown aloe vera leaves and how to easily fix and prevent it from happening.

Why is my Aloe Plant Turning Brown?

Aloe vera, one of the more adaptable succulents, is a happy houseplant in most cases. The plant has few problems as long as it has good drainage and light.

A wilting brown aloe can be caused by a number of factors. Continue reading for some causes and cures if your aloe is turning brown.

What Causes Aloe Vera Plant to Turn Brown?

The following are the most common reasons why Aloe Vera leaves turn brown:

1. Excess Moisture and Overwatering

Overwatering is by far the most common reason why your Aloe Vera leaf is turning brown. Given that this indoor plant is succulent, it actually prefers dry soil.

If you notice that the leaves have turned brown or yellow in color, rather than their natural shade of green, there is a good chance that the plant is overwatered, or the soil is holding too much moisture.

3. Excess Salt in the Soil

While this is not a common cause of browned Aloe Vera leaves, it is worth taking into consideration.

Unfortunately, Aloe Plants are very sensitive to salt, as well as various chemicals, like chlorine and fluoride.

4. Improper Light Exposure

Another common cause of browned Aloe Vera leaves is overexposure to direct sunlight.

While their rugged, desert-like appearance might make you think the plant would thrive in sunny conditions, too much light can actually burn the leaves.

5. Drafts Or Cold Air

If your aloe is suffering from cold shock, the leaves will begin to droop and turn yellow.

Eventually, brown will travel down the leaves towards the base of the plant. The leaves closest to the cold source will be lost first.

If left untreated, the entire plant will die from the cold or from cold shock.

6. Sunburn

Although aloe plants are often used to treat sunburn, they can be very susceptible to sunburn themselves.

An aloe vera plant that is getting sunburned will start turning red or brown, starting at the tips due to inhibition of photosynthesis.

The leaves of the plant may turn into a faded green color or they may develop brown spots on the leaves, sometimes called sunspots.

7. Too Much Fertilizer

Aloe vera plants don’t need much in the way of fertilizer. Too much fertilizer will cause chemical salts to build up in the soil, burning the roots.

The damage to the roots will begin to show as the leaves begin to brown.

Should I Cut off Brown Aloe Vera Leaves?

Trim off any leaf tips or whole leaves that have turned pinkish-brown. These parts are dying, so removing them helps the aloe plant stay healthy and green.

Use a knife for small and medium-sized plants, or sheers for large, thick leaves. The exposed end of the leaf will seal up on its own in time.

Can Brown Aloe Turn Green again?

Remove the plant from exposure to direct sunlight. Install the plant indoors. Gradually it will recover the usual green hue.

Perform watering of the aloe vera once every twenty days to avoid overwatering and the aloe plant turning brown again.

How Often should Aloe be Watered?

Generally speaking, plan to water your aloe plant about every 2-3 weeks in the spring and summer and even more sparingly during the fall and winter.

One rule of thumb for fall and winter watering is to roughly double the amount of time between waterings (as compared to your summer watering schedule).

Which Part of the Aloe Plant is Poisonous?

There are poisonous aloe species available, including Aloe elata, Aloe ballyi, and Aloe ruspoliana. They all have a leaf sap that gives off a very strong odor.

The first two species are rare and not widespread, but it’s important to know which kind you have before you try to use them. 

Can you use Aloe Right from the Plant?

This is a medicinal plant that people have used to treat various health conditions for thousands of years.

It’s usually very safe to use the aloe directly from the plant, or you can buy it in gel form. You can apply them topically to treat a range of conditions.
