1、 Root rot causes

For the maintenance of Douban green, root rot will occur when the basin soil is not properly selected or the water management is improper. If the amount of watering is too large at ordinary times, it will cause poor breathing of the plant roots, which will lead to root rot. After the rotten roots of plants are found, remedial measures need to be taken in time

2、 Remedial measures

If it is relatively minor, we can adjust the cultivation methods, such as changing soil and controlling water to restore the growth of Douban green

If it is serious, the rotten roots are obvious, and even some branches have rotted. We can cut off the green branches of watercress that are still normal in the front section and put them in a cool and ventilated place to dry for two or three days, and then cut again
