re: Getting wild grapes to produce more. Anybody here ever tried this?

I have a scuppernong in my back yard. I trim it probably every two weeks from the spring through harvest time in the fall. But I am limited in area in the yard. I cut back a lot of the new really small growth to keep it from being a crazy bush.

It has a horizontal run about 12 feet long and an arch in the opposite direction. Every year my yield has increased. I got 7 1/2 lbs. last year.

If you had more space and could let it go wild I bet you could get away with trimming it monthly. I will also add that I never completely cut mine back to the main stems though.
