I live in northern Illinois and it has full sun 3/4 of the day. Please help.

What to do with wisteria (vine type) that hasn't blomed in 8 years?
Stress the plant: stop feeding, cut way back on water, cut the roots with a shovel approx. 30" all around the trunk. It will feel its existence is threatened and seek to reproduce (by flowering).
Reply:Cut it back severely this autumn, and force the plant to produce new shoots next year. Also try fertilizing it just as the snow melts next spring. Wisteria grows somewhat like grapes, and to keep grape plants strong and vital, they're cut back every year.





If you don't want to lose all of your vines at one go, try cutting just half of the old vines this year and easing them gently out of the tangle. And then cutting the other half next autumn to complete the transformation. You could put white twist ties around the base of the vines that you are leaving intact for a year to distinguish them easily from the new growth, when you go to cut them next autumn.
Reply:Burn it down and try again.





Thats what I did to my house and my first family.
Reply:chinese wisteria can takeup to 20 years to flower after being planted.feed it a good mix of manure and compost.dont forget to prune and hopefully next year is the one.





tis is what a search gave me


Wisteria is a genus of about ten species of woody climbing vines native to the eastern United States and the East Asian states of China, Korea, and Japan. The vines climb by twining their stems either clockwise or counter-clockwise round any available support. They can climb as high as 20m above ground and spread at 10m laterally.





The leaves are alternate, 15-35 cm long, pinnate, with 9-19 leaflets. The beautiful flowers are produced in pendulous racemes 10-80 cm long, similar to those of genus Laburnum, but purple, violet, pink or white, not yellow. Flowering is in the spring (just before or as the leaves open) in some Asian species, and in mid to late summer in the American species and W. japonica. The flowers of some species are fragrant, most notably Chinese Wisteria. The seeds are produced in pods similar to those of laburnum, and, like that genus, are poisonous.





The genus was named after Dr. Caspar Wistar (1761-1818), a professor of anatomy at the University of Pennsylvania. As a consequence, the name is sometimes given as "Wistaria", but the spelling Wisteria is conserved under the International Code of Botanical Nomenclature.





Wisteria species are used as food plants by the larvae of some Lepidoptera species including Brown-tail. It is also an extremely popular ornamental in China and Japan as well as in the United States.











Wisteria, especially Wisteria sinensis, is very hardy and fast-growing. It is considered an invasive species in certain areas. It can grow in fairly poor-quality soils, but prefers fertile, moist, well-drained ones. It thrives in full sun to partial shade.





Wisteria can be propagated via hardwood cutting, softwood cuttings, or seed. However, seeded specimens can take decades to bloom; for that reason, gardeners usually grow plants that have been started from rooted cuttings or grafted cultivars known to flower well. Another reason for failure to bloom can be excessive fertilizer (particularly nitrogen). Wisteria has nitrogen fixing capability (provided by Rhizobia bacteria in root nodules), and thus mature plants may benefit from added potassium and phosphate, but not nitrogen. Finally, wisteria can be reluctant to bloom because it has not reached maturity. Maturation may require only a few years, as in Kentucky Wisteria, or nearly twenty, as in Chinese Wisteria. Maturation can be forced by physically abusing the main trunk, root pruning, or drought stress.





Wisteria can grow into an unattractive mound when unsupported, but is at its best when allowed to clamber up a tree, pergola, wall, or other supporting structure. Whatever the case, the support must be very sturdy, because old wisteria can grow into immensely strong and heavy wrist-thick trunks and stems. These will certainly rend latticework, crush thin wooden posts, and can even strangle large trees. Its pendulous racemes are best viewed from below. Wisteria is an aggressive grower which can quickly clog gutters, sometimes invade foundations, and cause other physical damage if not controlled. To avoid many of these problems, wisteria should not be planted near a dwelling.





Wisteria flowers develop in buds near the base of the previous year's growth, so pruning back side shoots to the basal few buds in early spring can enhance the visibility of the flowers. If it is desired to control the size of the plant, the side shoots can be shortened to 20-40 cm long in mid summer, and back to 10-20 cm in the fall. The flowers of some varieties are edible and tasty and good in salads, and can even be used to make wine. Others are said to be toxic. Careful identification by an expert is strongly recommended before consuming this or any wild plant.
Reply:Has it ever bloomed? I've heard that it can take wisteria 7 years to bloom after planting.





Maybe try something new, like a native Illinois plant that blooms more easily.
