When aloe vera has brown leaves: Common care mistakes

1. too much water: if you have overwatered the medicinal plant, the first thing you will notice is many spots on the leaves. These spots will slowly grow larger. The plant leaves look damp and drooping, the plant is floppy. If you do not solve the problem quickly, the roots will rot, the leaves will fall off and the plant will die.

Aloe turns brown what can you do

Possible solution: repot the aloe vera immediately. While doing this, carefully loosen the old soil from the roots of the plant and check the roots for rot. Cut off any rotted roots with sharp garden shears. The new soil should be for cacti and succulents. Use a new pot, terracotta pots and clay pots are best because the water evaporates faster. The new pot should definitely have drainage holes. Water the plant less frequently than usual over the next few weeks. It needs water maximum once a week, in winter you can reduce watering even more and water the medicinal plant once – twice a month.

2. too little water: basically, it is better to water succulent too little than too much. They can not tolerate wet feet. If you notice that the leaf tips turn brown and the leaves look dry and crumpled, then you should water the plant abundantly.

Water the aloe vera properly: Water the plant copiously until the water drains from the drainage hole. Then wait for the soil to dry out. If you notice that the soil is drying faster than usual, then you should check the temperature, humidity and light conditions in the room.

3. overfertilization: Aloe vera does not need fertilizer. If you fertilize it regularly, then you can damage its roots and the leaves will turn brown.

Possible solution: place the tub in the kitchen sink and rinse the soil for several minutes. Allow the excess water to drain through the tub’s drainage holes

4. heat and 5. sunburn

The aloe vera plant can tolerate temperature fluctuations poorly. Heat waves can damage it. Most of the time, this happens when you move the plant from indoors to outdoors during the summer. It thrives best at temperatures between 12° and 26° Celsius. In summer, it can also get sunburned in strong midday sun.

Possible solution: change the location. Even if the plant is now in the sunny winter garden, or on the glazed balcony, you should change the place. It is best to place it away from the sun and ventilate the room more often to cool it down.

6. draught or cold wind

Aloe vera also can not tolerate drafts or cold wind. Air conditioner, fan, a constantly open window can cause damage. In winter, you should also place the plant as far away as possible from the front door or sliding door to the garden to protect it from a draft.

Pests and diseases: Prevent an infestation

Aloe vera is susceptible to aphids, fungal diseases and various bacteria. Waterlogging favors the development and spread of germs and other pathogens. So proper care is very important. Avoid rotting by watering the plant less frequently, but abundantly.
