Answer: Wisteria plants will bloom early if they are budded, or grafted onto a rootstock. Most plants sold at nurseries are grafted - but sometimes seedlings are sold, and they won't bloom for years. Let's consider that yours is probably a seedling and should be ready to bloom within a year or two. This winter prune out or thin out some of the side shoots and long streamers, but don't prune off the flower spurs (thickened and different-looking than the rest of the wood). Don't fertilize this summer, and pinch out some of the buds that form late in the season on the trunk and old stems. Next summer you should have flowers, or at least the plant should begin to develop flowering spurs. Watch carefully and don't prune these off accidentally! Good luck!
