1、 Cause

1. Excessive water: when raising rich trees, many people cannot control the amount of water, which will lead to excessive watering. The plant is not resistant to waterlogging. When it grows in ponding, the root position cannot breathe normally, which will cause rotten roots

2. Bacteria invasion: when breeding, there are bacteria in the soil or harmful insect eggs in it. For a long time, it will harm the root of the plant, which is easy to lead to root rot. Or the water cannot evaporate, the soil is too wet for a long time, and the environment is not ventilated, which is also easy to rot

3. Frostbite: the temperature is very low in winter. If you don't pay attention to antifreeze, the plant will be frostbitten and the root will rot. The temperature can't be too low for a long time. You need to move to the house during the winter

2、 Treatment method

After rotten roots, check the rotten roots at the first time. If they are slightly rotten, there is no need to deal with them, but plant them again after the basin soil becomes dry. If the root rot is serious, the rotten part should be cut off and disinfected in disinfectant. Finally, it should be cultivated with clean soil
