Two summers ago we moved into a home with 2 huge grape vines. I didn't pick the grapes in time. When I saw they were good, I didn't go pick them for almost a week and they where dead. Sad. I pruned it back (maybe too much) and last year no fruit. This year I see buds, but I don't know what to do to make sure I don't kill it. This will be my third summer with them. But I am sure they have been here for many years. Maybe 10 or longer.
