sterile wisteria .??
I have an 8 yr. old wisteria that was flowerng when I bought it. I have trained like a vine to crawl along the top of a fence hoping the flower clusters would drape down over the fence top as I have seen others in the area do. This vine has never flowered again & yet I have a tree wisteria near by that never quits blooming all summer long!
I was told to try stressing it ... no fertilizer, cut back on watering, even chopping around the roots at the base to stress/encourage it to bloom but no luck! The nursery here says they can be tempermental... some bloom & some do not but to always buy one in bloom as I did & not to try & grow one from seed with the hopes of it blooming either!
Any ideas short of digging it out & tossing it?
