Wisteria is one of these. I call it a ‘two and eight’ shrub, since it needs pruning in February—the second month of the year—and August—the eighth.
To prune, roughly shorten new stem growth, taking it back to around five or six leaves from the base. This helps to get light and air to the wood that will produce the flowers next spring, which will make the flowers stronger and more impressive.
If you’re trying to train the plant along a support, leave a few of the new shoots, twine them through your support and tie in. Keep the ties fairly loose so the stem can thicken as the plant ages.
