I've been reading up about Wisterias and pruning and get the general idea but my problem is the climbing Wisteria in question has got really tall with 2 entwined stems from the bottom and only leafy growth at top and not flowering well. All the stuff I've been reading talks about whippy growth but I can't see that solving the problem of all the leaf growth being too high up. Not sure if that makes sense!! Can take picture tomorrow. Any advice much appreciated.
