1. On the one hand, because the plant is growing continuously, so when it develops to a certain stage, the demand for volume and other aspects becomes larger, so the previous maintenance containers and other conditions have no way to meet it, so in order to better develop the plant, we need to provide a better environment for it.
2. On the other hand, the long-term growth and development of the plant has absorbed and utilized almost all the nutrients in the original environment, especially the change of the cultivated loam, which is not only undernourished, but also poor in permeability and softness, so it needs to be replaced.

1. If the plant was originally raised in a small container, then it needs to change the basin more frequently, about 1-2 years.
2. If the plant is cultured in a larger container, it will be OK for about 4 years, during which care should be taken
3. The specific time of basin changing needs to be selected well. April May in spring is very good, because the environment temperature is suitable at that time, and the plant recovery will be faster.
