If your aloe is suffering from frost damage, sunburn, or rot, you’ve come to the right place. Today we tell you how to save an aloe plant from these catastrophes.
How to Save an Aloe Plant from Frost Damage
Aloe vera has its origins in warm and dry areas. It survives longer dry periods without water because it can store water in its leaves. However, this ability becomes her undoing in frosty conditions.
The aloe vera is one of the so-called leaf succulents, the plants that use their leaves as water storage organs. The leaves of healthy aloe are plump, the outer skin smooth and shiny. Even at temperatures below 5°C, the aloe plant, which is sensitive to cold, can be damaged. The water stored in the leaves freezes, the leaf tissue is destroyed and dies.
Avoid frost damage if possible
The frost damage can be recognized by the glassy, softened leaves, which later turn dark and die off. In older, strong plants, only leaf tips or individual leaf parts can be affected. Prolonged exposure to the cold can also damage the roots of the aloe.
In order to avoid such damage, you should bring your aloe plant that is left outside in summer back into the warm in September at the latest. The aloes can easily be overwintered at normal room temperatures. If you keep them cooler in winter (approx. 10-15°C), this promotes flower formation. In this case, you should water your aloe plant very little and not fertilize it.
Remedy for frost damage
Depending on the duration and severity of the frost as well as the general condition of the aloe, various measures can save the plant:
- First put the aloe in a bright and warm place, avoiding direct sun.
- Do not water the plant for a few days or weeks, so that the damaged leaves dry up and possibly fall off.
- Carefully remove the damaged plant parts, if necessary cut off with a clean knife.
- If the damage is more severe, check the roots and, if necessary, let them dry or cut them off.
If, after a while, new healthy leaves appear in the center of the aloe vera, your aloe vera has recovered.
You should also take care of your aloe if you ventilate it for longer in winter and it is better not to leave the pot near the open window.
How to Save an Aloe Plant from Sunburn
If your aloe vera turns brown, it could be suffering from sunburn.
The plant likes it bright and sunny. But if you suddenly put it in the blazing sun without getting used to it, your leaves turn reddish-brown and the tips dry out.
Therefore, bring an aloe vera plant outside of the apartment, first choose a partially shaded location. If too much sun is the reason for the brown color, the plant will quickly turn green again if you take it out of the blazing sun and move it to a less sunny place.
How to Save an Aloe Plant from Rot
If the aloe leaves are not only brown, but also soft to mushy, this is due to incorrect care. Usually it is a sign of too much watering and the water has build up in the soil. Aloe plants do not tolerate waterlogging at all.
In this case, stop watering for the next time until the soil has dried off completely. It is also worth repotting the aloe vera and providing it with some sandy soil.
When repotting, take a close look at the roots. If these are already starting to rot, it is probably too late for rescue measures. You can remove the rotten roots and try your luck. Maybe the plant will recover again.
