What to Do When Aloe Vera Leaves Turn Black? Cause Analysis and Solutions

Flowers & Gardening Jan 1, 1970 0 views

There are many reasons why aloe vera leaves turn black, and we need to take different measures to deal with them according to the specific situation. If it is caused by too much watering, you should reduce watering or change the soil; if it is caused by too little watering, replenish water in time; if the soil is not breathable, then change the soil; if the temperature is inappropriate, adjust it to around 25°C; if the roots are damaged, take careful care of it and wait for it to recover.

I. Caused by watering

1. Overwatering

In fact, aloe vera grown as a potted plant at home does not need too much water, otherwise waterlogging can easily occur, and over time the roots will rot, affecting normal root respiration and causing the aloe vera to turn black. At this point, we should reduce the amount and frequency of watering and replace the soil.

2. Too little watering

Although it is fairly drought-tolerant, it cannot go without water for a long time, otherwise the roots will dry out and the leaves will begin to turn black. At this point, we should water it appropriately and water it thoroughly in one go, and from then on just follow the rule of not watering until the soil is dry.

II. Caused by soil that is not breathable

When growing it, some people may not have loosened the soil for a long time, causing the soil to become compacted, which directly affects root respiration, and in severe cases the leaves also begin to turn black. At this point, we should loosen the soil in time to ensure good soil aeration, and the blackening of the leaves will disappear.

III. Caused by temperature

Usually it can grow very well at a temperature of 25°C. If the temperature is too low, its roots will slowly rot from the cold, and the leaves will turn black along with them. At this point, we should keep it warm in time and adjust the indoor and outdoor temperature so that it can grow normally. In addition, the temperature should not be too high either, especially in summer, when excessively high temperatures will scorch the leaves, and the leaves will also turn black. So when the temperature is high, it should also be cooled appropriately.

IV. Caused by improper repotting

When repotting, if you are not careful, it is easy to damage its roots. Once the roots are damaged, it directly affects the leaves and causes the leaf surface to turn black. So when repotting, be sure to keep the roots safe. If they do get damaged, you should take careful care of it and wait for it to slowly recover.
