Unsure how or when to prune. Lots of old branches show below top leaves and flowers, but still have a green centre. Am I able to cut these without killing my plant. Picture added. Thanks Fred Mason
Then it's a group 1 and should only be pruned to tisy it up and keep it in bounds as soon as flowering finishes. If you want to renew it, cut one or two big stems at the base and leave them to wilt completely before you try and remove them. They'll put up less resistance and do less harm to the rest of the plant.
Give it a generous feed of slow release clematis, rose or tomato feed now and again after pruning and make sure it doesn't go thirsty. That will keep it healthy and full of flowers next year.
