Two days before the banyan bonsai was replaced, it was first watered. That is to do not water on the basis of as much as possible, so that the basin and soil better separation, to avoid pulling out the banyan roots.
After pulling out, clean the basin soil, unload some surplus soil without spraying to the root, and observe the root condition. If there is rotten root or rotten root, cut off this part and disinfect it with potassium permanganate.
The first thing to choose a new basin is the size of the banyan tree. The basin should not be too small, which will hinder the growth, but it should not be too large. The large basin will cause the Ficus to absorb water and become trapped, and the roots will grow in vain downward. After selecting the basin, first cover the bottom with broken tiles, and lay river sand on it, then plant the plant, so as to enhance its drainage and permeability. After covering the soil, pat the basin to make it contact more closely.
Don't water the basin immediately after the completion, it's better to wait for half a day to do it again, and it should be fully poured once. In addition, if the root is injured, watering should be done every 1-2 days to avoid infection. After changing the basin, place the banyan tree in a cool place, not exposed to direct sunlight. And in the dry soil after the second water, after the normal maintenance.
