So when we moved in here, we planted one near our arbor. I waited for that first spring for the beautiful flowers, but only leaves emerged. A horticulturist advised me to wait, since wysteria doesn't bloom for several years. So I waited two years, three years, four years. Finally, I got some advice to "stress the roots." The idea is that when wysterias receive too much plentiful food, they don't bloom. If you take a shovel and cut straight down in a circle about 18 inches around the base, a lot of the roots will be severed, and it will "force" a bloom the next spring.
I tried it, but no avail. Finally, after six years of waiting, two years after I "stressed" the plant, my 20 foot tall wysteria finally bloomed. And what a bloom! The flower clusters are easily a foot to 18 inches long and so plentiful that it's hard to see out the top of the arbor. A few were closer to the ground and have a delicate perfume. These blooms are only partially opened--but I couldn't wait!
