Summer pruning wisteria encourages the development of short-flowering spurs that will carry the long racemes of bloom in spring. The long vigorous shoots are cut back to a couple of buds from the base of the current season's growth. During initial training of young wisteria plants, select a few strong shoots to tie into wires or trellis. Once you have created these, you can prune any sideshoots back to this framework.
