We have a big vine in back garden, stems on it as thick as your forearm, we think its been there 30+ years. It was supporting itself on some large trees and our garage - the trees had to be cut down last Autumn leaving the vine exposed. Now it appears to be dead - we hauled it from top of garage wanting to build a pagoda framey type thing under it so it would go all mediterranean etc., but that looks unlikely. Bear in mind the roots haven't been touched, but there are no buds at all anywhere on it.
Is it dead?
