It is a quick and convenient method to process and shape the tree bonsai with metal wire. According to the thickness and hardness of the trunk and branches, operators choose different thickness of metal wires to wind, and use the plasticity of the metal wires to change the original shape of the processed object and shape the ideal shape. This method is simpler and easier than the brown silk cutting and binding technology, and is widely used in the processing of tree bonsai. The metal wires used for processing tree bonsai are mostly bronzed aluminum wires specially made by professional workers. The specifications are complete and very suitable, and the color is very close to the bark. Amateurs often choose all kinds of copper wire, iron wire or aluminum wire according to their own situation. I think copper wire is better, followed by aluminum wire. Although the price of iron wire is cheap, it is easy to rust, and if it is tied in the tree for a long time, the hardness will become greater and it will be more difficult to remove.

Using metal wire to process tree bonsai, we must master certain processing skills. The order of treatment is the trunk first, then the branches, then the big branches and then the small branches, but sometimes it is not necessary to complete one branch at a time. Instead, all the main branches are wrapped with metal wires first, and then the angle and position of each branch are manipulated to determine the overall framework. After the big shape is determined, each twig is tied with a metal wire with appropriate thickness, and every detail is handled well. In the process of treatment, combine pruning to remove some unnecessary branches.

There are ten points to pay attention to when working on trees with metal wires:

(1) When winding the trunk, one end of the wire should be obliquely inserted into the pot soil near the root of the trunk, and inserted into the bottom as far as possible, and then the trunk should be wound from bottom to top, and then bent and shaped after winding.

② When winding each branch, the starting end must be fixed first. The fixing method is generally to bend one end of the wire into a hook shape and hook it on the larger branch in front. When winding for the first time, the end of the hook should be pressed down, and then it should be wound round and round. The winding angle (the angle formed by the conductor and the branch) is about 45 degrees, but it can be slightly looser according to the situation. When winding, one hand holds the wire and branches, and the other hand holds the wire and winds it forward. As the wire advances, the back hand will press the wire tightly with branches to prevent the wire from deviating and damaging the bark.

④ When winding, it can be clockwise or counterclockwise, but the winding direction should be consistent with the winding direction of branches. So winding, the metal wire clings to the branches, which is beneficial to bending and straightening, otherwise it will be loose and weak, which will affect the modeling effect and be unsightly. The winding should not be too dense or too sparse, and the distance and angle of each turn should be roughly equal, so that the force is more uniform and beautiful.

(4) Sometimes, when encountering hard branches, it is found that its strength cannot effectively bend the branches after winding them with ~ silk. At this time, an extra thread can be added and wound in the same direction next to the previous thread, and the shape can be adjusted by the strength of the two threads.
