I love my Concord grapes. I love the way they look as a live privacy screen on my fence. I love getting to eat them off the vine in the fall.
So when I had to severely prune them back last fall in order to make repairs to my fence, I worried that I might have killed them.Â Over-pruning can really impact grape production.
You can see the hatchet job I did on this poor vine. Because all the canes had twined through the fence, I had to lop them all off. Not looking good…
That said, with the severe haircut I had to give this vine, I won’t be expecting a bumper crop of grapes.
On this vine, below, I was able to preserve a few canes with buds, so I knew this one would come back.
You can already see that there will be several new canes on which to bear fruit. There should be plenty of grapes from this vine come September.
So I’m happy to report that it’s practically impossible to over-prune and/or kill concord grape vines.
Never-the-less, I should say that even in the best of circumstances pruning is an art of keeping balance:Â prune too much and you’ll wind up with a small crop; prune too little and you’ll get too many bunches of grapes of a lower quality fruit. The trick is to prune just right.
One of the reasons I grow Concords (aside from the fact that I just love how they taste) is that they are a very forgiving variety. Great for anybody who doesn’t have time to become an expert vintner.
Here’s a great primer on grape vine pruning, for anyone who is unsure of what or how much you should prune.
