1、 Why

1. It may be because the maintenance position is improper, and the plant can not receive sufficient light maintenance. We should know that light is still very important for plant development. Once it is lacking, it will have a great impact

2. Or the ventilation of the environment is not good, so that there is a lack of oxygen, and the plants can not exchange gas smoothly, which affects the growth

3. This phenomenon is more likely to occur when there is too much water, and the root system will lack oxygen. In addition, it will be damaged by soaking. Once infected, it is not just a problem of poor growth

4. If the temperature is too low, it will also lead to this phenomenon. The reason is that the tissue is frostbitten and lacks vitality

2、 What should I do

1. In daily maintenance, we need to place the plant in a good light area to cultivate, so that it can receive sufficient light nourishment

2. Let the gas circulate and ensure fresh gas exchange

3. If the root is seriously damaged, the basin needs to be changed and trimmed if necessary
