The Q&A Archives: Non-Blooming Wisteria

Question: I have a 5' tall wisteria and haven't seen any flowers for the last two years. I live in San Diego, California. I don't know what I'm doing wrong.

Answer: Wisteria can be so stubborn! You are in very good company my friend, you would be amazed at how many folks have difficulty getting wisteria to produce flowers. 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.
