When is it appropriate to prune Chinese rose trees?
Chinese rose flowers can be pruned all year round. Generally speaking, the best pruning time of Chinese rose flowers is May, June and August every year. You can choose the appropriate pruning time according to the growth state of Chinese rose.
Pruning in spring: the specific time is May-June, mainly pruning residual flowers, leaving 3-4 branches and buds for vigorous branches. Only 1-2 weak branches can be left.
Summer pruning: the specific time is June-July. At this time, the branches and leaves that are growing too vigorously should be pruned in time to avoid their growth competing with other healthy branches for nutrients. The trimming range is not large, and the original shape can be maintained.
Pruning in autumn: The specific time is around August. Branches that grow vigorously during the growth period, especially some lateral branches, can be pruned, leaving 2-3 branches on each branch, and the overall shape can be pruned, which has certain ornamental value.
Winter Pruning: Prune the rose in June 5438+February in winter, and prune its weak branches, some diseased branches, dead branches, old branches and leaves, and branches and leaves attacked by pests, so that it can regenerate healthily in the next spring.
Pruning skills of rose tree
Prune the leaves of Chinese rose once, with the height of remaining branches about 15 cm, and the pruning position about 1 cm above the leaf buds extending outward, and prune the lateral branches, diseased branches and concentric branches at the same time.
After May, after each flowering, 2/3 or 1/2 of the open flower branches should be pruned, so that there are more opportunities to regenerate a hundred flower buds.
If you want to make bloom big, you can also pick some buds for a long time, which can not only concentrate nutrition, but also achieve the purpose of prolonging the flowering period and opening in batches.
Matters needing attention in pruning rose trees
Pruning tools should be sharp and nontoxic. If diseased leaves and branches have been pruned, be sure to remember to disinfect them again when pruning.
When pruning, you should pay attention to pruning above the branch, and it is likely to hurt the bud point if it is too close to the node; The cutting mouth should be cut into an oblique mouth, so that when water accidentally touches water drops, it can slide down quickly to avoid the accumulation of Hei Bang in the cutting mouth.
Like a rose variety, there are several buds on a flower branch. If you want to grow up, you can leave only 1-2 buds on a flower branch and cut off the rest. As for a bud, there is no need to do so.
