Late winter is the time to prune grape and wisteria vines.
On other plants, branches that rub another or have broken may be removed now. Before making any cuts, look at the tree or shrub's overall form. Pruning should enhance the plant's natural shape. It also can keep a plant within a desired size as well as allow more air and light to reach the plant's interior. Make the cut just above the branch collar, or the swollen place where the branch and trunk meet.
