Red-leaf plum is a small deciduous tree or shrub of Prunus in Rosaceae. Its leaves are purple, gorgeous and charming, especially in spring and autumn. It is a common ornamental and colorful tree species and is widely cultivated in China. Red-leaf plums are often used in the greening of courtyards, squares and residential areas, and also in streets as roadside trees. Among them, the greening of squares, courtyards and residential areas mostly appears in the form of shrubs, and the greening of street trees is mostly arboreal cultivation.

Basal germination: Red-leaf plum has strong germination ability, and it is easy to germinate branchlets at the roots of clustered trees, and then wither to form dead branches, which affects ventilation and hygiene. In autumn and winter management, the thin sprouting strips should be removed in time to ensure the ventilation and sanitary conditions of trees. Thinning and cutting after greening and planting: The management of red-leaf plum after greening and planting is relatively simple, and the main pruning is thinning and cutting after defoliation in winter. Branching refers to thinning out too many sprouting branches, weak branches and branches with pests and diseases, improving the ventilation and light transmission of red-leaf plums and promoting the healthy growth of trees; Short-cutting refers to moderately short-cutting branches with great growth potential according to the tree type to inhibit their disorderly growth, affect the tree type and ensure the overall neatness and beauty of the tree. Branching and cutting can also be carried out in summer and autumn without affecting the landscape effect.

Plums, peaches and apricots all belong to the same compound-bud fruit tree (that is, flowers, leaves and buds are all in one place), which is extremely strong in germination and branching, and it is easy to flourish and form a tree among trees if it is not pruned properly. Trees in the plastic period should be planted as long as possible, with more auxiliary branches and deliberate consumption of nutrients, so as to alleviate the tree vigor and make it enter the fruiting period ahead of time. Pruning is mostly controlled by light picking, pulling branches and winding branches. Avoid big thinning and cutting, and finalize the design in one step.

The natural tree shape of red-leaf plum is spherical with obvious long branches and short branches; Buds can be divided into single buds and multiple buds, which are resistant to pruning and have long service life. Generally, the branches are not only bald, with dense crowns, crossed branches, strong uprightness and unbalanced trees. In order to improve the ventilation and light transmission conditions in the crown, the crown is enlarged upward, the main branches and lateral branches are evenly distributed, and the tree body is balanced. When pruning, the main branches should be gradually reduced from bottom to top, and the main branches should be sparsely arranged in layers on the central trunk.
