What to do if the roots of succulent plants rot

Causes of decay:

Rot is the most common disease of succulents, which is usually caused by fungal infection due to overwatering or too humid breeding environment.

Succulents mostly grow in desert climates and are adapted to extremely dry growing environments, so they should never be watered too much, and the soil should be allowed to dry out between waterings. Another cause of rot is a soil medium that is not breathable, especially for radish. Be sure to use a drainage medium so that water does not pool in the stems for more than a few minutes.

Some bugs such as mealybugs can also cause rot, especially root mealybugs. The wounds caused by these pests when they suck plant sap can cause fungal infections.

There are many ways that rot can manifest itself, and by the time you notice it, it’s often too late. Always be wary of discolored areas on the plant, as well as stems and leaves that become soft and mushy.

Crown rot:

Use a sharp knife to scrape away the infected part, then stuff the wound with crushed charcoal and flowers of sulfur. The wound should be completely dry.

Neck rot:

Cut off the rotten parts and treat the rest as cuttings. Remember to bury the plant only after the wound is completely dry.
