We transplanted this climber rose bush that still blooms beautifully. As you can see by the pictures it has disfigured the arbor I built. I am going to build a new arbor this spring. When can I cut this rosebush back and how much? Question number two when can I cut back the knockout rose bushes we have and how much? When can I cut back the butterfly bush and how much? Thank you so much for helping me out.
Here is a good link from New York Botanical Garden on pruning climbing roses
You can prune Knockout roses down to two feet tall in early spring. Also, remove any dead or crossing branches. It is a good maintenance practice to do this pruning annually. You will find additional information in this article. https://extension.umd.edu/hgic/topics/rose-rosenot-always-look-%E2%80%98knockout%E2%80%99-landscape-...
In general butterfly bush is pruned in the early spring with the onset of new growth. You can prune back to about a foot.
It should be noted that butterfly bush is invasive. See our website. You may want to take the opportunity to plant a native plant in its place. http://extension.umd.edu/hgic/topics/butterfly-bush
