Why is my wisteria not flowering?

We live in Michigan and my husband planted a wisteria vine several years ago. The plant itself has done well but it has never flowered. Just don't know why. I don't know what type of wisteria it is, but it should have been a climbing vine (which it is) with the large dropped purple flowers (which it doesn't have)

Why is my wisteria not flowering?
Many wisteria take an incredibly long time to flower. I planted 2 Wisteria sinensis about 12 years ago, and we've only had bloom for 3 years. All kinds of conditions can set them back, plus they're just slow to establish in the first place. I know it seems very strange to see this huge, spreading vine with vigorous growth and no bloom for years, but that's their way. Patience will reward you!
Reply:This sounds strange, but be a little bit mean to it. Dig a shovel in about a foot away from the trunk and cut at the roots just a bit. Give it a hard prune. Add super phosphate in the fall per the directions on the package. If the plant feels it is being threatened, it will try to create offspring by flowering/seeding the following spring.
Reply:One of the biggest culprits that can thwart your hopes for a blossoming wisteria is lawn fertilizer. If the wisteria plant gets too much nitrogen (the primary component of lawn fertilizer), it generally has no inclination to bloom. Make sure when you fertilize your lawn that you keep the fertilizer 2 - 3 feet away from the trunk(s) of your plant. Also, wisterias prefer acid soil, so if your soil has a lot of limestone, you may want to feed it with a high-acid fertilizer. In addition, be sure that your wisteria has a good place to climb, such as a STURDY trellis or similar structure. keep it away from trees, as it can potentially take over.
Reply:It takes a long time for them to bloom. About 7-8 years and that is if the top is in the sun and the bottom is in the shade.
Reply:Happy wisterias (well nourished and watered) aren't particularly interested in flowering, as they don't feel their survival is threatened. Try stressing them for a while, no food, less water. Also trim the roots back.
Reply:It is a Japanese Wisteria, and it takes 7 years of maturity before it will bloom.





Q. Why doesn't my wisteria bloom?








A. Youth could be the problem since seedling plants require several years to flower and sometimes fail to flower at all. Grafted plants, the kind purchased at nurseries and garden centers, should not have this problem.








Reluctance of wisteria to bloom abundantly is usually due to a lack of one or more of the following cultural requirements: full sun, good drainage, and light fertilization in the fall, not spring. Another essential is annual pruning, which can be done by





shortening new shoots to five buds in summer. If a grafted or cutting-grown Chinese wisteria refuses to flower in three or four years after planting, or a Japanese wisteria is barren after about seven years, prune it heavily and fertilize with superphosphate. If this fails to produce blooms root-prune by driving a spade into the soil 24 inches from the trunk around the plant.
Reply:Thanx it didnt flower. Otherwise there would have been fear of being deflowered.
