Most of the time it rots because the soil is too wet. Once the flower soil is too wet, there is likely to be water in the soil, and its roots are easy to soak in the water and then rot. In addition, overwet flower soil is very suitable for the propagation of some pathogens, it is likely to breed root rot and stem-based rot, which will also lead to its root rot.
Solution: first of all, we need to find a way to drain the excess water from the soil. If it's a potted plant, it can be put in a cool and ventilated place to evaporate the water. If it's a potted plant, we can loosen the soil for more air.
However, if the situation is serious and it is already ill, we need to use thiram or other drugs to treat it in addition to drying the soil. But if it's potted, it's easier. We can take it out and disinfect it directly, and then plant it in new flower soil.
If you don't take care of it carefully, it is likely to have worms. In addition to some insect pests on the leaves, there are also some underground insects. This kind of insect will bite its underground roots and cause it to rot.
Solution: if this is the case, we need to root it. Although it is time-consuming and hard, it is also quite effective. In addition, we can also use some drugs to help deal with this problem, such as thiamethoxam and pyrethroids, not only the effect is very good, but also no residue.
