Once it is found that the leaves of Ping'an tree have turned yellow, the yellow leaves should be cut off immediately. Even if they are not cut off, they also consume nutrients and affect the ornamental value. If the situation is more serious, it needs to take off the basin to check its root system state, see if there is rotten root system, if there is a need to immediately clean up, and then re cultivation.
Note that it is better to replace the previous soil, because some bacteria will remain in the soil, if planted directly, the plant is likely to rot again.
1. Less water: use a small amount of water at ordinary times. Do not store water in the basin soil. The amount of water should be properly controlled. In addition, in rainy days, we should take measures to avoid rain
2. Shade: in summer, it can't be raised in the sun. Let it grow indoors or in a cool place like the shade of trees. But also as much as possible to spray some water, to supplement the water it needs.
