If your bonsai is sure that Ficus microcarpa is not completely dead, it is necessary to cut off all the branches of Ficus microcarpa as soon as possible, put them in a sunny place, strengthen fertilizer and water, and trim all the branches of Ficus microcarpa, mainly by shaping and cutting them short, so that new leaves can grow within one month, with thick and dense leaves and strong ornamental value.
If Ficus microcarpa dies completely, only Ficus microcarpa can be cultivated as a rootstock, but Ficus microcarpa can only be cultivated as a potted plant, and its ornamental value as a bonsai is not high, but it grows very fast.
Banyan bonsai must not be placed in a cool place, or even a ventilated place, which will lead to poor growth and even death. If you want to appreciate it, you should wait until the leaves, branches and shapes are ready before putting it in the right place, but the time should not exceed one month, otherwise the leaves will fall off easily, because banyan trees are sunny and not tolerant of shade.
