When they have finished flowering - and for most of us that is around the middle of June - is the best time to prune all this year's new shoots back to a spur, leaving no more than about 6 inches of growth."In the process the whole plant can be tidied, trained and tied in so that there are no loose, trailing shoots."For those unsure about precisely how much wisteria growth to cut back, Monty Don offers clear direction: "If there is any doubt about how hard to prune, err on the side of cutting too lightly and then in the new year, when the foliage has all died back, you can prune again, reducing each side shoot to just 2 or 3 inches."
