Plastic pruning in winter has an important influence on the growth and tree shape of buttonwood. If winter pruning is not timely and reasonably carried out, the tree shape will be disordered, the main branches will be long, and the leaves will be few or low, which will greatly reduce its ornamental value and shading effect.

Timely and reasonable pruning can make the tree majestic, straight and beautiful in a short time, with dense branches, many and symmetrical side branches, lush leaves and natural enhancement of the tree.
