Wisteria

Anonymous added on July 18, 2015 | Answered

Just printed off "How to Propagate a Wisteria," but how do you get a really OLD wisteria plant to produce more blooms? This plant is in bush form in an old home place and would like to see it bloom more and to have a piece of it for my own yard. Thanks.

I would consider root pruning it. This will limit its ability to take up nitrogen, which will slow the growth and should get it to bloom more.

These articles will help with both current pruning and getting it to bloom:
