1. Main reasons

(1) Watering too much: aloe is afraid of waterlogging. If you water too much at one time or too often, it is easy to lead to rotten roots

(2) Bacteria: if the watering method is more scientific, you can consider whether there are bacteria in the root. If this is the reason, then the treatment must be disinfected

2. How to deal with

(1) First, get the plants out of the pot, and then remove the soil around the roots. Cut off the rotten part with a sharp knife. Until the healthy stem is cut thoroughly, do not leave any rotten part, otherwise it is easy to continue to rot and the area will be larger. After pruning, apply some plant ash to disinfect. After the wound is dried, continue to plant it in the basin. You can apply rooting element appropriately to accelerate rooting. Covered with plastic film, about half a month later, new roots can grow

(2) If it is observed that the root rot is not particularly serious, you can just dry it without pruning. However, it is generally recommended to trim it. Otherwise, it will easily lead to the expansion of the rotten part, and it will be difficult to reprocess

(3) In addition, the four or five leaves in the lower part should also be removed to reduce evaporation

(4) The plant should be placed in a semi shady place with good ventilation to accelerate the healing of the wound. Pay attention to less watering during this period of time
