I have a Tabebuia impetiginosa that has been engulfed by a lady banks rose for a couple of years. I cut back the rose today and found the tree to be about 3/4 girdled in several places from being rubbed by the rose branches. The tree is still in bud and the top (the only part above the rose) looks good. I was wondering, if I have to cut back the tree, will it regrow from the stump? The damage is pretty severe. Thanks for any input.
