1. Root pruning: when the root system of Phalaenopsis rots, it is necessary to dig out the plant from the basin as soon as possible and clean up the soil around the root. Find clean and toxic scissors and trim the rotten parts. Do not be reluctant to prune, as long as there are rotten parts should be cut off.
2. Disinfection: after trimming the root, potassium permanganate shall be used for disinfection. After disinfection, the root shall be placed in a relatively cool place for drying. At the same time, the old soil used before should also be replaced, or disinfected, or even if it is put into the basin again, it will be rotten again.
3. Potting: after the Phalaenopsis is disinfected and dried, it can be put into the potting soil again. Its root system should be buried in the soil. Do not damage the root system during the potting. After potting, you should first maintain it in a cool place with air circulation for a period of time.
When watering at ordinary times, the water quantity shall be strictly controlled, and the basin soil shall not be allowed to accumulate water. The soil should also use good ventilation and drainage capacity, and take good measures to prevent rain when it rains
