Never get flowers on my Wisteria and I've had it for 4 years. I planted it on the south side of my porch. I never clip it back. Last year I didn't water it thinking this was the problem. I also have a trumpet vine with the same problems and Idid the same with that.

and they may not have a long enough growing season to put out flowers. How soon does it freeze and die back to the ground each year? Most flowering plants need a given amount of "warm hours" in ratio to "cold hours" annually to perform as they are supposed to. Really all I can suggest is that you pamper them through the winter, especially before you get your big snows,and they should flower as the plant ages and matures. As you may already know, it is a good idea to provide lots of organic material such as compost, fertilize regularly with a 5-10-10, and, I would also check the soil. Most vines like a well drained, fertile soil . You could have a soil deficiency that is causing the whole problem. Check with your local extension agent about having a soil test performed. Other than that...I am getting ready to dig up the 7 year old trumpet vine in my yard. and they may not have a long enough growing season to put out flowers.
