Wisteria delivers a beautiful spring display, but this vigorous vine needs plenty of pruning to keep it from swallowing the garden.
“Wisteria are very vigorous vines and can climb easily to 30 to 40 feet,” said Neil Bell, a horticulturist with Oregon State University Extension Service. “They can be quite heavy and should be grown on a strong structure.”
When people see the jaw-dropping blooms erupt in mid-spring, they covet wisteria for their own garden. But, they should first know that in addition to the proper support, the vine needs vigorous pruning.
