Buxus macrophylla wood is hard and brittle, and its branches are thin and easy to hurt, so we should pay attention to pile selection first, then adapt the tree to the situation, and the shape must be mainly trimmed. You can also tie the sola with a rope properly, and it takes several times to branch it in place, that is, you can't be demanding or eager to achieve success, otherwise it will be counterproductive. Avoid twisting branches with rusty iron wires to prevent skin damage and dead branches.

The trunk of Euonymus japonicus bonsai grows slowly and vigorously, but the twigs grow faster, and the density of leaves will inevitably lengthen, making it soft and loose. Only by "pinching" can the ornamental value be guaranteed. That is, before the branches are lignified, one pair, at most two pairs of young leaves are left, and the rest are picked or cut off. Under proper water and fertilizer conditions, two buds will be issued in ten days and a half months. In this way, its branches appear short and thick, and its leaves can be multiplied by the product of 2, which constantly improves the ornamental value. Then it is necessary to sprout in time. Boxwood began to sprout before summer and autumn, and bloomed in spring. The nutrients needed by flowers and fruits account for 70%-80% of the whole tree, which will inevitably affect its normal growth and beauty. We mainly look at leaves. Therefore, it is necessary to sprout from the beginning.

The roots of Euonymus japonicus are mostly fleshy and fine roots, and its water and nutrient absorption is mainly the absorption function of root tip, followed by the length of root arm. The root is too long to stretch out in the pot. Bending and folding are very harmful. Moreover, in order to absorb nutrients, the root tip will naturally extend forward and contact new soil. The roots grow long, and it won't be long before the root tips hit the wall. Although the root tip will turn, it takes time and energy to affect the growth. In particular, the wall and bottom of the basin will soon be covered with roots, forming a soilless "root plate" and changing the basin body. This forms a vicious circle. Change the pot with soil (it is not advisable to borrow more soil) and cut off the long roots exposed on the soil surface. The best season for changing pots is early spring (the roots can germinate after being fixed). Second, summer is a season of vigorous growth (after changing pots, put them in the shade for seven or eight days and they will recover).
