Thanks for all the advice on all these different types of trees I've been posting. Its appreciated. So for me probably Feb March pruning then?Wisteria macrostachya 'Blue Moon' is a nice select cultivar of the native to Kentucky wisteria species. It has nice fragrant flowers and often reblooms sometime later in summer after the main flush of flowers in spring. It needs to be quite a bit larger trunk diameter to get to blooming size. Let it grow out long runners, then late winter, prune it back to shape. Yearly pruning back to shape. They love water in summer. If you are having trouble keeping up, you can sit it in a shallow tray of water, just for the heat of summer.
I cut it back every fall some. The trunks are surprisingly still pretty flexible even though they are starting to get thin bark so I think I will still be able to style some in the future.Nice find! My local Home Depot doesn't stock Wisteria unfortunately; I really wanted to try one out. Are you planning on cutting back really hard to build taper? I would have thought that wiring it while it was still flexible would have been the best idea if you're going for an informal upright style.
