How/when Should A Climbing Rose Be Trimmed After A Catostrophic Trim

Question

It fell off it’s trellis during a bad wind storm this winter, and was trimmed back VERY far to get it back to a manageable size. A bracing fence has been put around it (about 8ft off the ground), and it has been sprouting all over the remaining trunk and branches (it was about 15-20 years old, and went up ~ 20 feet and then spread on the high trellis another 20 feet). It’s sprouting is so enthusiastic, I wonder if I should choose winners and trim some, since there are so many new branches being made, mainly closer to the ground, much fewer higher up. I assume the ones coming out of the ground are from the root, which I assume is not necessarily the same rose as my climber.

Answer 1

IF you know for sure the rose was grafted, then yes, the ones coming from the ground are likely from the grafted root. You may want to leave a couple to see what they produce and remove the rest.
