Pruning Old Trumpet Vine
Our trumpet vine grows over a fence and was thoroughly established 20 years ago when we moved here. We prune it back to the top of the woody stalks every fall and it starts new vines and blossoms all summer. The woody stalks now have huge woody knobs on the tops from all the shoots. Can we cut off the huge old tops and still get new growth in the spring?

Because this is a trumpet vine, yes you can do this. You may see that it is not as full the first year following, but it will fill back in in about a year or so.
