1. When the pothos is raised in water, its root growth speed is relatively fast, and it is easy to have too long root system. After that, it should be cut short with scissors. Note that the scissors must be disinfected first. If you don't pay attention to pruning, the nutrients in the water will be lost faster and the plants will grow slower.
2. After the water becomes poor, the root of the plant will also become rotten, and there will be sticky things on its root, so it should be cut off as soon as possible. To keep healthy and growing roots, weak roots should also be cut.
3. There are also some roots with dense growth, which will absorb the nutrients in the container and cause the root system to grow too luxuriantly and the branches and leaves will not grow. If this is the case, we should also prune the roots so that nutrition can be delivered to the branches and leaves of the pothos.
After pruning the unhealthy root system, it is better to use potassium permanganate to disinfect and then maintain it again. At the beginning, we should change water frequently. After its root system recovers, we can change water normally.
