1、 Pouring water before changing Basin

Two days before changing the basin for banyan bonsai, water it first. That is to say, water as much as possible on the basis of no ponding, so as to better separate the basin from the soil and avoid damaging the root when pulling out the banyan tree

2、 Retaining the soil block at the root

After pulling out, the basin soil shall be cleaned, and some excess soil shall be removed without spraying on the root. At the same time, pay attention to the condition of the root. If there are rotten roots or rotten roots, this part shall be cut off and disinfected with potassium permanganate

3、 Preparation of new basin and new soil

Choosing a new basin first depends on the size of the banyan tree. The basin should not be too small, which will hinder growth, but it should not be too large. A large basin will cause the banyan tree to absorb water and become trapped, and the root will grow downward. After selecting the basin, first cover the bottom with broken tiles, spread river sand on it, and then plant it, so as to strengthen its drainage and air permeability. After covering the soil, pat the basin body to make it contact more closely

4、 Water the basin in time

Don't water the basin immediately after it is finished. It's best to wait half a day and pour it thoroughly at one time. In addition, if the root is injured, watering should be separated by 1-2 days to avoid infection. After changing the basin, put the banyan tree in a cool place and don't be exposed to direct sunlight. And after the soil becomes dry, replenish water for the second time, and then it can be maintained normally
