managing grape vines
I have 10 grape vines: Concord, Niagara, Lambrusco. I have never really learned how to prune....well, They've gotten over grown and I have usually fallen into the pattern of just giving them a crew cut every other year.
Well, the question is this: at the end of the season, should I cut them all the way back the the original main 'stalk', or will this dammage the plants? TIA!
