1. Pruning period
Vine roses need to be planted for more than two years before pruning, usually in late winter and early spring, after defoliation in the north and the coldest month in the south, usually in12-1; Daily pruning can also be carried out according to the actual situation; Pruning before and after flowering is beneficial to the rational utilization of nutrients and will not be wasted.
Step 2 prune every day
The vines are tall and grow rapidly, and the branches and leaves are easy to be messy, which affects the shape and needs regular pruning. When pruning daily, cut off long stems and messy branchlets to make their distribution more reasonable and maintain the ideal ornamental effect. In addition, it is necessary to cut off dead branches and diseased branches to maintain nutrition, avoid pests and diseases, and make plants grow healthily and vigorously.
Pruning before flowering
The flowering period of vines is very long. Pruning before flowering can promote flowering and prolong flowering. When pruning, the top branches and buds should be cut off first, and then the branches that grow too densely should be thinned to avoid losing unnecessary nutrients and provide sufficient nutrients for the later flowering of the plants.
Pruning after flowering
After the vines bloom, they also need pruning. When pruning, cut off the residual flowers and dead branches, and thin off the branches that are too long and too dense, which is convenient for the ventilation and light transmission of the plant and is conducive to the flowering and growth behind the plant. When pruning, be careful not to re-cut, and give priority to light cutting to avoid damaging the plant.
Winter pruning
The pruning effect of vine rose in winter is better than that in spring, which is more conducive to flowering in the coming year. Because in winter, vines enter the dormant period, when pruning, the flow damage is small, and the nutrition can be concentrated on the leaf buds, which is conducive to the growth of strong leaf buds, and the flower buds can bloom more when they are strong.
(1) winter cutting principle
Winter pruning can not be re-cut, we should keep strong main branches and strong secondary and tertiary branches. The stout new branches that grow from the roots need to be preserved, and these branches are pregnant with future buds. Don't cut off strong branches, and don't shrink or top them.
(2) Cutting position in winter
First of all, we should cut off diseased branches and insect branches to avoid the spread of pests and diseases and expand the affected area.
Secondly, we should cut off the old branches. Usually, branches that grow for 4 to 5 years will age, so that the flowering ability of branches will decrease and the germination ability of new branches will also weaken. It's no use keeping them, it's only a waste of nutrition. Aging branches are characterized by grayish white or grayish brown in the middle and lower cortex.
You can also cut off the twigs at the roots, so that on the one hand, you can reduce nutrient consumption, on the other hand, you can improve ventilation and light transmission, and reduce the probability of pests and diseases.
Cross branches and dense branches that affect growth and plant type should be cut off to avoid affecting ventilation and light transmission. Branches that grow in the axils of leaves should also be trimmed, strong and long branches should be shrunk, three full bud points should be kept, and weak side branches should be removed.
