1、 Avoid strong light

Its growth is inseparable from light, but only astigmatism. If it is exposed to direct light, it will be sunburned and prone to yellow leaves. If it is caused by this situation, move to a slightly cool place as soon as possible, and spray water on the leaves to moisturize them at ordinary times, so that they will recover slowly

2、 Leaf cutting and spraying

Its yellow leaves, if caused by macula, are mostly infected with leaf blight. This disease has yellow spots on the leaves in the early stage, which will expand in the later stage, and the leaves will fall in severe cases. In this case, the leaves with macula should be cut off in time, and sterilizer should be sprayed to avoid further infection. Pay attention to more ventilation in the later stage

3、 Reduce watering

If the plant is watered frequently during the management period, or watered heavily every time, it is difficult for the plant to absorb it. After a long time, there will be ponding, poor root respiration and gradually yellow leaves. Move the plant to a ventilated place and loosen the soil carefully to let the water evaporate as soon as possible. If the yellow leaf phenomenon is serious, it is best to take off the pot, trim the rotten roots, and plant in the pot again after treatment. Pay attention to reduce the amount of water in the later stage. It's better to be less than more

4、 Proper fertilization

Rich trees consume more nutrients in the peak growth season. If they do not supplement fertilizer for a long time, they are easy to lack nutrition, and the plants will also show yellow leaves. It is suggested that thin fertilizer should be applied frequently in the peak growth season, and compound fertilizer solution can be given every half a month, so that the growth will be more vigorous and yellow leaves can be avoided
