How do you grow pinot noir grapes in a backyard garden in central California?
Grapes only grow properly on specific latitude lines and at specific temperatures and humidity levels. The Central Coast of California is famous for its grapes and wineries, much like the south of France. Freezing temperatures will kill vine-bearing fruits; the Dakotas have a tendency to have frost warnings, even in mid-summer...so planting grapes in North Dakota would be possible, but a bad idea. Anywhere in California is preferable to the Dakotas.
