What Does Healthy Aloe Vera Look Like?

Why Aloe Vera Is Turning Brown

1. Overwatering 

Almost for every tree, pouring an excess amount of water is harmful. So if you keep overwatering your plant, gradually, some spots begin to grow in the leaf, and it will eventually turn brown and look mushy. The roots of the plant will also suffer due to overwatering. So without the necessary steps, that plant will end up dead. 


Firstly, you need to change the pot of the plant. It will help to reduce the damage. Secondly, clean the slushy dirt which was made by overwatering. Remove the damaged root with scissors. Then carefully put your plant in the new pot with fresh soil. 

2. Excess amount of fertilizer 

Some people put fertilizer keeping the phrase ” The more, the merrier,” but it’s completely different in the case of Aloe vera. It is not necessary to put too much fertilizer for its growth. Excess amounts of fertilizer will harm the roots, and the leaves will turn brown.


In case of too much fertilizer, you need to douse the soil with clean water, which washes away the chemicals. Do it for a few minutes. After a while, the water will automatically come out. In this way, the extra chemical or fertilizer will be cleaned.

3. Underwatering

If you don’t give enough water, you will see brown leaf tops as a result. Eventually, these brown tips will spread, and the whole leaf will no longer show any green. If your soil is not well-drained, the root will begin to show rotting effects.


You should water your plant whenever you see dry soil. Water it until it gets fully loaded and extra water comes out from the holes. You also need to be careful in the summer season or any specific day when the temperature is high.

Because, in those situations, you need to water it again and again as it would become dry quickly. 

 4. Excessive-heat 

 Aloe vera can be susceptible to direct sunlight. It will turn red at first due to the inhibition of photosynthesis. It can also show brown spots on the leaves as a result of getting sunburned. 


 If you see that the soil is drying out too quickly, it means it’s suffering from excessive heat. So you need to change its place and remove it from direct sunlight. It’s better if you can keep it in the shade to get at least a minimum amount of the sun.

Keep watering your plant more than usual in case of sunburn. Also, don’t keep your plant in the low light. In that case, the leaves will sag below and may show brown spots.

5. Environmental change 

These plants cannot adjust to sudden temperature change easily. So if you change the position of it in the summer and put it under direct sunlight, the leaves will turn brown or red due to excessive heat. For the rising temperature, the soil will also dry out quickly.


It would help if you gave your plant time to adjust to the rising temperature. So at first, keep your plant under a shade and gradually change its position to the warmer side. Remember that you need to do it slowly; the plant needs proper time to acclimate to the rising temperature and heat.

6. Pot problems

If your potted aloe vera plant doesn’t have enough drainage holes, the roots will not be able to breathe as it was deprived of enough oxygen. As a result, it will cause the root to decay, and eventually, the whole plant will turn red or might die.


It would be best if you used plots with enough holes. Sometimes the holes get blocked by sands and perlite, so you need to be careful about that. In that case, you can use a sharp shear to clean the hole.

7. Cold damage 

Your aloe vera can also turn brown due to cold wind. The part situated beside the cold source will be affected first. It occurs when the temperature is below 50°F. 


To keep your aloe vera warm:

  1. Don’t place it beside air conditioners, refrigerators, and fans.
  2. In times of winter, try to keep your plant inside the house or beside e warmful source.
  3. Try to keep the temperature below 50° F to prevent cold shock.

8. Attacks of pests and insects

Aloe vera can be attacked by pests (mostly Mealybugs and Snout Beetles), which is another reason for turning brown. It happens more when it is kept outside. Various insects and pests find it quite attractive. 


You can use pesticides to prevent that. In terms of fighting pests like ” Mealybugs, “you can destroy its existence by a steady stream of water. Fungus attacks can also do good damage. But if you don’t overwater your plant, it can’t spread that much.

Dry soil prevents the fungus from spreading. In the case of pests, always remember to keep the infected leaves away from the healthy ones. If you wash your plant throughout the year timely, the eggs of insects will be cleaned out. 

Besides, if your plant is situated outdoor and faces excessive rainfall, the soil will become overly wet. The stem then will feel soft. Gradually the leaves can also turn black or brown.

So do not keep your plant outside your house in the rainy seasons. Several leaf diseases can also be the reason for changing the color. Remember, you cannot prevent or solve all the problems by yourself. So try to take the help of a professional gardener or agriculturalist. 


Aloe vera plants are not very difficult to grow; you just have to take care of a few facts. Aloe vera plants usually recover quickly if the problems are removed. It doesn’t take much to bring it back to life if adequate measures are correctly handled.
