1、 Replace flower soil

Reason: the most likely reason for the rotten root of green rose is that it is watered too many times, or it is watered too much at one time, resulting in ponding in its flower soil. After that, the accumulated water was not discharged in time, resulting in the root whiskers of the plant soaking in the water for a long time and rotting

Treatment method: first take the plant out of the soil, and then trim off its rotten and black roots. After that, find some new soil with drainage capacity and plant it into the new soil for maintenance

2、 Treatment of diseases

Cause: some pathogen infections can infect plants and make them sick. They will gradually destroy the root system of the plant and let it rot

Treatment method: similarly, first take the plant out of the flower soil, and then cut off the diseased roots. After that, put it in the bactericide for about 30 minutes, and then put it aside to dry. It can be replanted at low concentration, and it can be replanted every other period of time

3、 Raise the temperature

Reason: long time low temperature will make it suffer from freezing injury, and the root system will also be damaged, resulting in the problem of decay

Treatment method: raise the temperature of the breeding environment, and it is best to adjust it to 15-25 ℃
