Pruning and modeling of plum blossom bonsai: Pruning is extremely important to make plum blossom bonsai both simple and vigorous and robust. Because the flower buds of plum blossom are formed on the new branches of that year, the old branches should be cut short immediately after flowering every year, leaving only 2 ~ 3 buds, and pay attention to making the buds grow outward, so that the flowers in the next year can be colorful. Pruning of plum blossoms can be divided into the following categories: (1) thinning, that is, various cross branches, parallel branches, overlapping branches, opposite branches, long branches and branches that affect the beauty of the tree. To achieve the principle of "the old branches do not move, leaving the strong and the weak".

(2) Short cutting: that is, on the basis of thinning the branches, the upper parts of the annual branches after flowering are cut off. The degree of truncation depends on modeling requirements and growth potential. Those with good growth can be cut less, and those with poor growth can be cut more. According to the needs of modeling, sometimes you can leave a few long branches properly. When cutting short, you should choose the direction of the bud mouth according to the direction and angle of the branches, so as to achieve density.

(3) Bud picking: When the leaf buds grow to about 3 cm in April every year, some unnecessary buds are picked according to the position and density of the buds and the needs of trees modeling. For the buds on the old stems, they are picked together with the hair.

(4) Picking: In late June, when the new buds grow to a certain length, the top buds are picked to control the growth of branches, and the general length should be 15 ~ 30cm. Mume with poor germination ability can be picked in advance to promote its re-germination. Plum trees tend to weaken when they are too old.
