Wisteria is not exactly a low-maintenance climber, but training it carefully is worth the effort.
IIn the past few years, I have not come across many well-trained or even well-maintained wisterias, here on the French Riviera. Many house owners inherit these versatile climbers from the previous owners, who all too often have already let them become overgrown, twiggy, criss-crossing and generelly out of form. Usually Wisteria becomes less and less flowering the more it overgrows, until it stops blooming completely.
