My grapevine has went crazy and engulfed a large tree. Do I need to prune it back, and if so, how much pruning should I do?
There are two grapevines planted approximately 10 feet apart. They are producing prolifically; however, the vines themselves have gotten out of control. I want to be able to put the grapevines on an arbor and place a bench under the grapes. Any ideas?
