1、 Why rotten roots

1. Soil culture: for soil culture, it is generally because the basin soil itself is not breathable for a long time, and the water in it is difficult to evaporate after being applied, so there will be water accumulation. Then there is watering too much. If you think the plant likes water, you don't apply water according to the demand, but apply water all the time, resulting in ponding in the basin. If the root grows in such an environment, there will be no way to breathe, which will eventually lead to rot of the root

2. Hydroponics: the main reason is that the water is not changed in time. If the water inside is not changed for a long time, the water quality will become turbid. It is difficult for plants to survive in it, and rotten roots may occur

2、 How

1. Replace with new pot soil. The material of flowerpot can be tile pot with good air permeability, and the loam inside also needs to ensure air permeability. Cut off the rotten roots of the plant, then wash them in clean water, replant and cultivate them, and pay attention to the application of water in the subsequent maintenance, not wantonly

2. If the water quality becomes turbid, replace it in time. Generally, change the water once every 5 days in summer and 7 days in winter
