Q.wisteria vines
I planted a wisteria plant last summer and it took very well. It probably grew at least 8 feet. The vines went woody in the fall, then it went dormant. This spring none of the existing vines came back in, but I have new growth coming in a the base of the plant. Aren’t the existing woody vines supposed to come back in?
You should be seeing growth from the vines.
It is possible that the vines were damaged in the severe cold winter that nearly the entire United States suffered.
New branching and buds are formed on old wood, and even a late spring cold kill the buds.
I would continue to care for the plant and perhaps the old vine can just serve as a support.
Here is a few links with more growing and pruning information.
