When pruning vines and roses in winter, it is necessary to prune the dense, overgrown, dead and diseased branches on the plants to make their distribution more reasonable. When pruning main branches and side branches, we should pay attention to retaining side buds, which can promote the growth of new branches and make them easier to climb and grow. The new branches of the year should shrink and cut off the lignified parts, and keep strong buds.
It should be noted that in order to ensure flowering in spring, pruning should be carried out at this time, and light pruning is better.
