What to do if the cactus turns yellow

Overwatering

Cause Analysis

If a lot of mucus oozes out of the surface of the cactus, you should pay attention to whether its roots are rotten. If the roots are rotting, overwatering may be the cause.

Treatment

Cut off the rotten part of the root, place the sphere in a ventilated place for maintenance, avoid direct sunlight, and do not water. If the degree of rot is greater than ⅓, then congratulations, you have earned the title of "plant killer".

Lack of water and exposure to the sun

Cause Analysis

The surface of the cactus turns yellow and appears to be withered, which is probably caused by long-term lack of water and exposure to the sun.

Treatment

If you encounter this situation, it is relatively easy to deal with. Generally, you only need to water it and move it to a slightly cooler place indoors for prevention and treatment. It won't take long before it will turn into a green plant again.

Sleep disturbance

Cause Analysis

Cactus has its growing season. It grows relatively vigorously in summer and enters a dormant period in winter. If you water it at this time, it will cause root rot.

Treatment

Do not water the cactus during its dormant period, remove the rotten roots, and place the cactus indoors for rest.

Pest impact

Cause Analysis

Cactus must be protected from diseases and pests. If the pests are serious, the cactus will show symptoms of rotting and withering.

Treatment

Eliminate pests in time and spray them with insecticides.
