Pruning time of plum trees is generally carried out in summer and winter. Pruning branches in different seasons can coordinate nutritional balance and facilitate early fruit and high yield. Mainly concentrated in four periods, that is, before flowering, fruiting period, full fruiting period and no fruiting period.

2. Pruning before flowering: plum trees in the early flowering period grow faster and tend to grow too thick branches. Too dense branches affect the opening of flowers and need to be pruned in time. Pruning must be lightly cut, mainly to wipe off the newly grown buds and maintain the best tree shape.

3. Pruning in fruiting period: Pruning plum trees in fruiting period aims to enlarge the crown and increase fruiting branches, thus achieving the purpose of increasing production. Pruning focuses on dense branches to make the overall tree shape better. When pruning, each main branch should be cut off to reduce the density of branches, improve the ventilation conditions of plum trees, increase illumination and save nutrients.

4. Pruning in full fruit period: the main branches of plum trees have grown up in full fruit period, and the growth of the trees is relatively moderate. At this time, it is necessary to improve the nutritional composition of plum trees, which is a principle that must be followed in pruning. At this time, the fruit of plum trees should be protected. Usually, we will prune those unnecessary weak branches, cut off redundant branches, reduce nutrient consumption, and let the fruiting branches absorb more nutrients and bear better fruits.

5. Pruning in non-fruiting period: At this time, the plum trees will have fallen leaves and dead branches after picking, and we also need pruning. Pruning is mainly to cut off dead branches and old branches to preserve nutrients. This pruning is not only beneficial to overwintering, but also saves nutrients and promotes new shoots to form new branches faster.

6. Pay attention to pruning because of trees: when pruning plum trees, we should follow certain rules according to the differences in tree height, crown size and topography in the orchard, and strive to transform them into different types of trees to achieve the best results.

7. Pay attention to flexible pruning and shape with branches: due to different growth conditions of trees, the height, crown size, branch ratio, branch direction, number of backbone branches and distribution affiliation are different. Therefore, when pruning, we should not only have requirements for the tree shape, but also master it flexibly according to the different conditions of each tree, take advantage of the situation, guide it according to the situation, and induce it to form, so as to achieve "tangible immortality, living without chaos"

8. Pay attention to the combination of light and heavy, and prune properly: When pruning fruit trees, it is necessary to pay attention to distinguish the situations and minimize the amount of pruning, especially the pruning and shaping of young trees. Proper light pruning and more branches are conducive to expanding the crown, relaxing the tree potential and achieving the goal of early fruit and high yield. However, the pruning amount should not be too small, so we can increase the pruning intensity according to the growth of trees, otherwise it will inevitably reduce the number of branches and long branches, which is not conducive to plastic surgery, and may also lead to slow growth and reduce fruit yield.

9. Pruning plum trees is essential. Pruning plum trees with different pruning time and methods can improve the growth and shape of the trees, adjust the nutritional balance, absorb necessary nutrients, and achieve rapid and fruitful results. This is the purpose of pruning plum trees.
