1、 Environmental maladjustment

If the plant has just arrived in a new environment and has not fully adapted to the surrounding environment, the leaves may turn yellow. This situation is easier to alleviate. It only needs to stay there for maintenance. After it adapts itself, it can recover and become more prosperous again

2、 Incorrect moisture

The water was not applied according to the growth status of the plant, and too much water was poured, so that the root could not fully absorb it, or the plant could not absorb it due to lack of water, which delayed its growth. If there is too much water, it is necessary to speed up the evaporation of water and put it in a ventilated place. If it is lack of water, you can pour a little into it step by step

3、 Incorrect nutrition

Lack or excess of nutrients may cause the upper leaves to turn yellow. If the young leaves turn yellow, it means that there is too little fertilization and nutrients need to be applied in time. If the young leaves are very thick and uneven, it is necessary to control fertilization and add water to promote the discharge of residual nutrients

4、 Poor ventilation

This phenomenon can also be easily caused by plants in a closed environment for a long time. It can be placed in a well ventilated place to promote air circulation
