Talkback: Pruning wisteria
in Talkback
We started wisteria growing up a post to the top of our pergola and it is just now reaching the canopy to start spreading. I haven't pruned it at all because I don't want branching below the canopy. This should work, shouldn't it? (Might take longer to get lots of blooms, I realize.)

Pruning and training depends on how you want to grow your wisteria. Most people want to train a wisteria to cover a wall or pergola, so you need to train the main leading shoot in the desired direction. As side shoots develop these can be tied in to produce more of the main framework. Future summer and winter pruning aims to shorten side shoots developing from these main stems of the framework, encouraging flower buds to form at the base of every sideshoot. Just picture a long horizontal stem trained along the wall of your house with flowers cascading down from in at regular intervals along the entire length.
