Let me tell you about the functions of pruning flowering shrubs after blooming and the introduction of green plant cultivation methods and precautions in the field of green plants and flowers, which will surely bring you help. Let's learn about it together!
Pruning of flowering shrubs and hedges is one of the most frequent types of pruning in landscape gardening. How to properly prune flowering shrubs and Swedish hedges?
【1】Pruning of newly planted shrubs.
Shrubs are generally transplanted bare-rooted. To ensure survival, strong pruning is usually performed. Some precious shrubs with soil balls, such as purple magnolia, can be lightly pruned before planting. Flower buds of plants that bloom in the same year must be removed to promote survival.
1. Shrubs with a trunk or small tree-like.
Such as peaches, Ulmus pumila, etc., when pruning, a certain main trunk is usually retained, selecting 3-5 main branches with a suitable direction, evenly distributed, and strong growth, shortened by about 1/2, the rest are thinned, and if there are lateral branches, 2/3 are thinned, and the remaining ones are shortened by 1/2.
2. Shrubs without a trunk.
Such as forsythia, roses, etc., many branches of similar thickness grow from the ground. Select 4-5 evenly distributed and normally growing shrub branches, shorten them by 1/2, remove the rest, and prune them into a round shape with the inside higher than the outside.
【2】Pruning of maintenance shrubs.
1. Maintenance pruning of flowering shrubs with a distinct trunk.
It is generally pruned after flowering, shortening the branches that have finished flowering, leaving 3-4 buds. In the spring, when the new shoots reach a certain length, they are pinched to promote flower bud differentiation. After pinching, the secondary branches are also pinched. Leafless flower spikes should not be shortened, and dense branches can only be thinned. When shortening, the cut must be a leaf bud, not a leafless bud. If the upper part becomes stronger and the lower part weaker, the upper branches should be cut off in time, dense branches, weak branches, and aging branches should be thinned, and the flowering branches should be evenly distributed.
2. Maintenance pruning of clustering shrubs.
The central branches of clustering shrubs should be thinned. The outer clustering branches and small branches should be shortened to promote diagonal branches. If the planting time is long, old branches should be thinned out in a planned manner to cultivate new branches. Regularly shorten the long branches that stick out of the shrub to maintain a neat and balanced shape. After flowering, promptly cut off the remaining flowers and fruits to prevent nutrient consumption.
【3】Pruning of hedges.
Generally, the cross-section of hedges is a trapezoid with the top smaller than the bottom and a rectangle with the same size top and bottom. For hedges that have been shaped, measure from the ground up to the specified height with a wire, set up a pole at each end of the hedge, pull it to the specified height, and prune off the part above the rope with a flat剪. The requirements for shaping pruning are consistent height, neatness, flatness of the top and all sides, clear edges and corners, timely pruning to ensure new branches for festivals, and丰满 growth. Hedges are generally pruned 2 to 4 times a year.
