1、 What kind of soil should be used

1. When selecting soil, it should be used with very fertile soil with first-class drainage effect and a lot of humus in the soil It is better to be acidic, and there are many particles in the soil, which will be relatively loose and soft. There will be more powder in some soil, so you can't choose, because if the time is too long, the soil will harden

2. In terms of flowerpot, it doesn't have much requirements. As long as the size of the pot can meet it and there is enough space for it to grow. But it's best not to choose a very light plastic basin, because it will crack easily

2、 Loosen soil and replace with a new basin

1. Generally, this kind of tree is planted in a relatively large basin. Because its tree is relatively large, it should be loosened once a month, so that the soil can remain loose all the time. When loosening the soil, be careful to use tools and don't hurt its roots

2. If it is a relatively small tree, it can be replaced once a year. If it is a relatively large tree, it is generally replaced once every two or three years. When replacing the basin, you don't have to replace all its soil. It's enough to replace only one third, and then cut off the broken roots on its roots, so that it can continue to grow safely

3、 Fattening

1. It prefers fertilizer. In its growing season, it should use compound fertilizer once a month. If the air gets cold in autumn, it should use fertilizer such as phosphorus and potassium to strengthen its ability to resist the cold

2. In winter, we should stop adding fertilizer to it. If the leaves turn yellow and fall when we want to add fertilizer, it shows that the method of adding fertilizer is wrong. If the root is damaged, we should immediately replace it with a new basin for treatment
