I have a couple of grape vines along a 3 wire trellis. Here's a picture of one of them. I've had these in the ground for three years. The first winter, this vine died back to the ground. Last year it overwintered well, and hopefully it will be fine this winter. I haven't had any grapes yet.

How would you prune this vine? I'm assuming I could do it now? I thought I would prune it and then post another picture of the results. Maybe it will be useful for others to see.

Thanks.
