Wisteria can be so stubborn! But you're in good company. Many folks have difficulty getting wisteria to produce flowers. Sometimes wisteria won't bloom for 7 years! Proper pruning can help achieve your goal. A few other tips to keep in mind: Remember that wisteria needs full sun, and, if you have an unnamed seedling rather than a grafted variety, it may take decades to achieve bloom! When fertilizing wisteria, be careful with your choice of fertilizers, I stick to a superphosphate. Now, for the pruning: All through the summer, prune out the tips of all new shoots when they reach 12" long. In the winter, shorten the shoots again so that about 6 buds remain on each shoot. Cut away all suckers that appear at the base of the plant. Hope your wisteria blooms next season!
