Hello, I live in Michigan, and I have a concord grape vine that has long been established since I moved here 7 yrs. ago. I have never pruned or trimmed it. This year it produced 8.5 lbs or 2000 ml. of juice. (which I am very happy with) Anyway, I was told that pruning or trimming the vine is very important. I do not have any idea on how to do that. My vine is growing on lattice. Also can I start new vines with seed from my grapes. JAMBMEN IN MICH
