Q.pruning grapes
I am removing blackberry vine from old grapevines. It is late for pruning the grapes I know. How far back do I prune the grape once I get the berry vines out and off the grapes? The grapevines I have cut back are bleeding. I want to get them back under control. Kristal

It all depends what purpose your grape vines are serving. Are you using them to bear fruit or are they more decorative on a fence? I have grape vines in my backyard that serve a decorative purpose only. If your grape vines are for decorative purposes, I would say prune them as far back as you want. If they are for fruit, then you can't be as carefree in your pruning.
