Will I kill my sweet autumn clematis if I prune it now?
I know I'm supposed to prune this clematis in early spring but it never gets done and it's out of control. It grows up a pole supporting my deck and onto the deck railing. The deck floor is about 7 feet from the ground and then it grows up another 4 ft. to the top of the rail and spreads in both directions. The problem is the pole is near my walk-in garage door and the large stalks are beginning to look like tarzan vines looping out from the pole where they broke out of their ties. The vine is probably 20 years old or more. I'm in the mood to tame it now but I sure would miss it if I killed it. Thanks, Linda, Ohio zone 5a
