I was lucky enough to have some grape vines on this place. I didn’t do very well to maintain them and they died. Still got the trellace, should plant some more and take care of them.
We have grape vines. They don’t require much taking care of, just water all spring and summer, a little fertilizer once a year and pruning back in the Fall. We even dug them up and moved them once from a side yard to the back yard and they still came back! Yours must have had root rot from ants or some fungal disease...............
