Pruning young plum trees is essential for shaping the tree and promoting early fruit production. The primary approach involves light pruning and gradual release, focusing on maintaining large auxiliary branches to fill the canopy quickly and reduce the tree's vigor, thereby encouraging earlier fruiting. To open up the main branches, techniques such as supporting, pulling, or using spreaders are applied, with an ideal angle of 65 to 80 degrees. Encouraging the growth of outer buds helps improve the tree’s structure. Auxiliary branches typically consist of flat or oblique lateral shoots, and sometimes upper oblique shoots can be selected by directing them downward. Plum trees have short branches that produce many buds and grow upright, which can lead to dense growth. To maintain good air circulation and light penetration, it's important to remove excessive shoots in early spring and thin out crowded shoots during summer. Summer pruning should also focus on cutting back long, competing branches and adjusting the direction and angle of secondary shoots to promote a well-shaped canopy. If the main branches and side branches are uneven, strong branches can be shortened, their angles increased, and smaller twigs retained. Weak branches, on the other hand, should have their angles raised, more twigs left, and their growth extended slightly to balance the tree’s overall potential.
For full-bearing plum trees, the method of changing the stem branch head is commonly used to regulate the apex’s growth and maintain the tree’s size and stability. Peripheral branches are pruned to be sparse, removing long, dense, and competing branches while keeping a few strong and medium-length ones. Retaining some shoots slowly allows for reduced foliage at the periphery, improving light conditions in the inner and lower parts of the tree. This helps enhance fruit quality and the development of high-quality bouquet-like fruiting branches. Pruning should be done selectively—removing old, weak, or unproductive branches while retaining new, vigorous ones. A planned renewal strategy ensures the tree remains productive and healthy over time.
In the late fruiting stage, older plum trees tend to sprout on the back of main branches, so timely pruning is crucial, especially during the summer. Aging fruiting groups should be pruned back to maintain strong growth. All dense, weak, or unproductive branches must be removed. For mature trees that show vigorous growth but low yields, the cause should be identified. If it’s due to excessive pruning, the amount should be reduced to avoid over-thinning. Proper pruning ensures the tree isn’t too dense and doesn’t suffer from poor fruit set. For trees that bear too much fruit, leading to weakened vigor and inconsistent yields, pruning should be adjusted accordingly. Increasing pruning slightly, combined with proper water management, can help restore the tree’s health and encourage better nutrient growth.
