Blue Moon Wisteria growing over pergola, pruning??

11 years ago


I planted a Blue Moon Wisteria vine last summer at the base of my 16'x14' pergola. It has two vines growing from the base (each about 3-4' tall), and I want to know how to train it. Should I cut one of the stems off, and let just one reach the top of the pergola? Should I twine the two stems around each other? Would that kill them? I know the wisteria gets thick, woody stems and the Blue Moon should be plenty hardy in zone 5. Please let me know!
