1. Winter is the sleeping period of Yushu. At this time, it is necessary to prune Yushu reasonably and properly, and cut it short to prevent long branches from competing for too much nutrients.

2, pruning after flowering, Yushu's flowering period is after the spring and summer festival. After flowering, the nutrient supply on flowering branches is insufficient, so it should be cut off and pruned to grow new branches.

3, winding metal wire, this method is to use metal wire wound on the branches, in order to achieve the purpose of making the branches grow according to their own wishes.

4, growth pruning, Yushu grows faster in the growth period, so it is necessary to prune the diseased branches of Yushu and the branches that cannot meet the requirements of the use purpose. In the growing period, because Yushu grows faster, it should be watered less to avoid controlling the overall shape.

The method of pruning is topping, cutting off the tips of dissatisfied branches to prevent them from growing in this direction. If it is an old tree root and the root system is relatively developed, it is necessary to cut off the residual roots and miscellaneous roots, keep the main roots, and do not water them after pruning to avoid rotting roots. Let the repaired roots heal naturally before watering.
