Question about cut-down Concord grapevine
A few weeks ago, I posted a question about several bushes of ours that got cut down to the ground. They were a blueberry bush, an American cranberry bush, and a grapevine. Most people who responded thought they would all grow back.
The good news is that both the blueberry bush and the cranberry are growing back! :) OTOH, while I've heard that grapevines are hard to kill, I don't see any signs of life from the grapevine. It was 2-3 years old. At the very longest, if it's still alive, how long would it take for the grapevine to show some visible growth?
