1、 Can you live

Cactus can also be saved after decay, as long as the rotten place is cut off and properly disinfected and dried. After drying, plant it again and put it in the shade to wait for it to take root. As long as a new root grows, it means it has been saved

2、 How to treat

1. Proper pruning: the rotten places of cactus not only cannot provide nutrients, but also continue to be infected. All of them should be cut off. Before trimming, disinfect the scissors with potassium permanganate solution to avoid the bacteria on the scissors infecting the wound

2. Dry the wound: the pruned cactus can't be planted immediately. Wait for its wound to recover. Put the plant in a cool and ventilated place and wait for it to dry in the shade. It cannot be placed in the sunny place, otherwise it will lose water seriously due to light, reducing the possibility of survival

3. Replant: after the wound of cactus is dry and shrinks, it can be replanted. Prepare sandy soil with good air permeability as the matrix, and pour a little water to make it slightly moist. Plant the plants inside and don't bury them too deep

4. Subsequent maintenance: put the planted cactus in a well ventilated place, which can accept a little scattered light. The temperature should be properly controlled to avoid high or low temperature affecting its growth. The large temperature difference between day and night is more conducive to its recovery
