Once you find that Bai Mudan has fallen leaves, don't expect it to recover, because black rot is irreversible. Once the leaves begin to fall, they must be dealt with immediately. The sooner you deal with it, the greater the hope of saving Bai Mudan.

Treatment: immediately dig out the roots of the black rot plant, then behead it and keep her upper body. Don't be reluctant to behead until the stems of plants are not black. If the beheading is not clean, Bai Mudan will still be lost. Throw away the rest of the poles. It won't be all right. Don't give up hope. The cut head can be treated with carbendazim and rooting powder, and her wound should be dried. When the wound is dry, you can put it on the soil and let it grow again. Secondly, it should be raised in a well-lit place to strengthen ventilation. Generally speaking, Bai Mudan likes light.

Note: fallen leaves generally rot slowly and cannot be used for leaf insertion and reproduction. In the future, while cultivating succulents, we must prevent and deal with black rot.
