Pruning method of purple leaf plum

After the purple leaf plum is planted, it is cut short at the stem height of about one meter. Generally, the first germinating branch under the cutting mouth grows the most vigorously. As the extension branch of the central stem, three thicker new shoots are selected as the main branches. The three main branches are required to be evenly distributed on the central stem and develop obliquely upward at an angle of 45 °, and they are picked in the growing season to promote the growth of branches and extension branches of the central stem. During the growth period, if there is uneven differentiation between main branches, it can be adjusted by supporting, pulling, cutting, leaving bud direction, pushing inside and outside buds and other technologies

Winter pruning of purple leaf plum in the second year

When cutting in the winter of the next year, properly cut the trunk and extend the branches, and leave strong buds at the cutting mouth in the opposite direction to the previous year, so as to ensure the straightness of the trunk; The three main branches shall be cut short to varying degrees according to their growth, and the external buds shall be left at the cutting mouth, so as to continue to expand the crown. During the growth period, pay attention to the growth of steep and long branches, or remove or pick the heart

Winter pruning of purple leaf plum in the third year

During winter cutting in the third year, continue to short cut the main and extended branches, while leaving the second layer of main branches for short cutting to expand the tree crown. As long as the initial reading of other branches on the trunk does not exceed one-third of the thickness of the trunk at the place where they are born, they can be placed for a long time without cutting. If they are too thick, they should be retracted to the outward short branches

The fourth year of winter pruning of purple leaf plum

In the fourth year, the third layer of main branches shall be selected. In addition, when each main branch is cut in winter, an appropriate number of side branches shall be gradually equipped, and attention shall be paid to the scattered distribution. After pruning every other year, just cut off dead branches, pest branches, inward branches, overlapping branches and Cross branches; For the long thin and weak branches, they should be retracted and rejuvenated in time< span>
