When to Cut Back Star Jasmine

If the vine is terribly overgrown, you can reduce each vine by one half. Again, each cut should be made on the diagonal, just ahead of a bud. After pruning a star jasmine, pick up the cut pieces and dispose of them. You’ll need to attach the remaining vines to the support with ties.
