1、 Cause

1. If the plant is short of water and the root system cannot absorb enough water, this phenomenon will certainly occur. Shrinkage is certain. As for withering and yellowing, some tissues are damaged and cannot grow normally, so it will happen

2. On the contrary, it is impossible to give too much water. Imagine that the root system of the plant is soaked in 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. In this way, the plant will be in danger and face death in serious cases

3. It is also possible that the light is too strong and directly damages the tissue, so the leaves will turn yellow and the whole tissue will dry

2、 Solution

1. Daily water supply should be appropriate and well-known. You can't give more or less water, only if the plant is well developed

2. Shading treatment shall be given in hot summer, and containers with good air permeability shall be used for curing
