It should be pruned once in summer, and it can be pruned into a flat shape or a spherical shape or a conical shape in autumn according to different greening needs, and the branches should be properly thinned to maintain a certain crown-shaped branching state. Measures such as piling up soil to prevent cold can be taken in cold places in winter.
