The old boxwood stumps excavated in Shan Ye can only be processed after 1 ~ 2 years, while the seedlings cultivated since childhood can only be processed after 3 ~ 4 years. Modeling is mainly based on climbing, but also rough cutting and fine cutting. Boxwood branches are hard and thin, so it is not suitable for climbing with wire. It is best to use brown wires or plastic sheathed wires. When climbing with metal wire without plastic skin, wrap the metal wire with cloth strips and plastic sheets, otherwise it will easily hurt the bark. Loosen the branches in time after bending and shaping, otherwise the wire will be easily embedded in the bark. If the larger branches can't be bent once, they can be bent twice. Be careful to break the branches when pulling. For big branches, you can use the method of "half-sawing" to saw several saws at the parts to be bent. After bending and fixing, clean yellow mud should be applied to the sawed-off part and wrapped with black plastic film to facilitate wound healing. Climbing period is mostly in spring, and pruning can be carried out at any time. Poplar types should be inclined stem type, curved stem type and cliff stem type. In the traditional form of "Yangpai" bonsai, the branches and leaves of boxwood are all made into "clouds" by "fine binding and fine cutting", while in the "Supai" bonsai, they are made into "steamed buns" by "coarse binding and fine cutting", each with its own characteristics. Buxus has strong germination ability and is very resistant to pruning, and it can also be processed into a natural tree by pruning. If the boxwood bonsai is matched with Shi Xiu, it will become a "boxwood basin stone". In this way, boxwood with small old trees will be born next to the stone, and its state will be more natural and wonderful.
