Clicio, most of the leaves are at the ends of the branches. Are you saying I should trim it how I want it now? If I do that there won't be leaves left.
No, I am not saying that.
IF this wisteria were mine, I would wait for the right time and chop it down to create a more dense and short tree.
They are very difficult to style, by the way. Unpredictable and wild.
