Expert Response

Thank you for your question about growing Concord grapes in your USDA Zone 5b garden.  Concord grapes are considered very hardy, surviving temperatures as low at -30 Degrees F.  See this article from Penn State University Extension:

The average annual extreme minimum temperature in your zone 5b garden is -15 to -10 degrees F.    

Concords are described in the research literature as being "very hardy", and they should be hardy for you in Gambier.  Make sure that you purchase from a reputable source so that the stock is vigorous.  Here's some information  from OSU's Ohioline on planting, pruning, and fertilizing your new grapes:

Good luck with your grape growing.
