How long does it take for bonsai modeling binding?

Bonsai modeling generally takes a growing period, that is, 3-4 months, and it takes 2 months if it is fast. The reason for controlling the binding time is that the binding time is too short, and the branches are not shaped, which can not achieve the effect of shaping. If it is tied for too long, the iron wire will sink into the bark, and in severe cases, it will block the cambium, resulting in poor juice flow, affecting the development and beauty of plants, and even causing them to die.
