Reasons Why the Aloe Plant Turning Brown

Aloe plants, when they are healthy, present plump leaves and many offspring, and these Aloe babies are the main indications that a plant is healthy; if a plant is giving you offspring, it means that it is in good condition.

To begin to address the main causes why an Aloe plant, or some of its leaves, begin to darken and turn brown, greenish, gray, and even purple, we need to keep in mind its main characteristic:

This plant is considered a natural, useful, and affordable medicine, which possesses incredible healing properties in gel form.

Exactly; gel, crystal, juice, you can call it whatever you want, but where he retains its miraculous qualities is in its internal liquid, which is primarily water. This ability to store water in its leaves and classify it as a succulent plant will be the key to understanding why the leaves darken.

So, if it retains water inside… let’s give it water! Lots of water! That’s what our logic tells us, right? However, despite having this watery gel inside, they tend to want to be a bit dry and therefore, most problems are caused by overwatering or the wrong planting medium (substrate) holding too much water.

Not all water-related problems are excessive watering, as brown aloe vera plants can suffer from too much or too little moisture. Certain people, too careless or too busy, tend to forget about their plants and leave them too dry for too long which can lead to the same result as overwatering.

Being the excess or lack of water the two main causes of Aloe Vera darkening, it can also be due to an excess of salt in the soil, fungal diseases, sunburn, heat or cold shock, chemical toxicity, or nutrient deficiency. Guessing the reason for the leaves changing color is simply a matter of trial and error.

But your biggest problem will not be the color of the leaves, but the overall health of your plant. I am afraid that the brown color of the leaves of an aloe stalk that is being overwatered is a reflection of rotting roots, a fungal attack, or even worse; a bacterial attack.

3- Aloe Plant Turning Brown Due to Extreme Heat or Cold

Aloe Plant Turning Brown Due to Extreme Heat or Cold. Most Aloe varieties prefer warm temperatures. Those that are not exposed to air currents may develop some foliar (leaf) damage because they cannot dissipate heat easily. You should move the plants to a warm place with good air circulation. Aloes prefer temperatures of 55 to 80°F (13°C to 27°C).

Aloes prefer plenty of light (not direct sun); however, when placed in a southern location by a window that directs heat and light to the plant without ventilation, the leaves can become sunburned. The ideal would be bright, but indirect light.
