1. If the plant is short of water, the root system can't absorb enough water, which is sure to happen. It's certain that it's shriveled. As for withered and yellow, some tissues are damaged. There's no way to grow normally, so it will.
2. On the contrary, it's not good to give too much water. Just imagine that the root system of the plant has been immersed in the water for a long time, and there is no way to breathe. There will be some bacteria in the water. When the tissue of the plant is damaged, it will be infected, so that the plant will be dangerous, and in serious cases, it will die.
3. It is also possible that the light is too strong to hurt the tissue directly, so the leaves will turn yellow and the whole tissue will dry.
1. The daily water supply should be adequate and well-known. It is not allowed to give more or less water. Only the plants are well developed.
2. Shade treatment shall be provided in hot summer, and containers for maintenance shall be of good air permeability.
