We just bought a house w/a well established yard. The previous owners had planted a beautiful Wisteria vine that they have grown upwards ending in a a tree-like bush with a full canopy. We haven’t pruned it yet, not knowing what it was, so is it too late? If we prune it a bit, will it still give us leaves and hopefully purple flowers?

The flowerbuds of wisteria are produced during the summer (on last year’s wood), so wait until late spring or early summer to prune the vine. Pruning the previous year's growth too severely will remove the flower buds, but that is rarely the case. Most people do not prune severely enough. Severe pruning is often recommended, back to three or four buds, to keep the plant manageable and renewed.
