1. Reasons for rotten roots

The main reason for violet root rot is too much water. The method of watering is unscientific, resulting in the soil being too wet for a long time, or being drenched by heavy rain in the rainy season, which may lead to rotten roots

2. What if it's rotten

This problem needs to be discussed according to the situation. First remove the plant from the pot and observe the state of its roots. If the root rot is very serious and most of the roots are rotten, there is basically no way to save it. If only a small part of the root system is rotten, it can be saved through efforts. After removing the pot, trim the roots first, mainly cutting off the rotten roots to avoid the expansion of the rotten parts. Then, disinfect the root with bactericide. After that, put the plants in a ventilated place until the roots dry. After that, add the basin again. Watering shall be controlled in the near future, and normal watering shall be carried out after the plants completely return to normal

3. Correct watering method

It should be judged according to the state of the surface soil. Water it after it is dry. If it is not dry, it will not be watered for the time being. No ponding is allowed in the basin. Watering is different in different seasons. Generally speaking, watering is more in growth and less in winter. In addition, pay attention to the humidity. It is more appropriate to control it at 40% to 70%
