Q.Why Did I Only Get One Bunch Of Grapes From A Mature Vine?
I have one vine in the backyard. About six years old. I have had 2 years of a decent crop and last year I pruned the vine for the first time around November. I cut off all the green growth. This year I got one small bunch of grapes but plenty of green growth. They are the green Thompson grapes. Why did I only get one bunch of grapes from a mature vine?

You should prune out the old wood. Old canes don't produce. These care tips should help produce more grapes:
