I thought this might interest you. When we moved into this house three years ago, the wisteria was a wild, giant bush, growing up and over the old back fence. I pruned it severely then built a pergola and stood up the wisteria between the posts. For two years I just kept it pruned and began tying up the long stems, using planters tape. In November, I started the nest design with all of the stems circling back and around the center (see photo). I expect it will look amazing when the blooms emerge. Joel
