If the new roots of trees are not well developed and the roots are not densely covered with the bottom of clods, the original pots can still be used without pruning the roots. For trees with well-developed roots and densely covered with clods at the bottom, a slightly larger pot should be replaced, the dense roots should be thinned, the old roots should be removed, and a small number of new roots should be left to turn over the pot. When turning over pots, some old piles of bonsai can be properly lifted to increase their ornamental value, and the old roots and root tips can be trimmed to make them loose.
Some old piles of bonsai can be raised appropriately when turning over the pots to increase their ornamental value. Old roots and root tips can be trimmed and cultivated in loose and fertile soil to promote the generation of new roots.
