Patients is the key to wisteria - it generally is 7 years or more before they are mature enough to bloom. Don't prune it past the sixth set of leaves and don't prune it when it is setting bloom buds - it blooms on new wood.

I have seen wisteria bloom sooner than 7 years old, but only a couple of times.

glad i didn't know that when i bought it cuz then i WOULDN'T have bought it!!!(GRIN)

thanks, phyl

Try pruning it, that may help.
