I haven't every tried to grow food for the deer but lawdy, we seem to do it accidentally. We are in eastern Virginia (zip is 22438) and we grow corn and soybeans in the summer, winter wheat and barley in the winter, with lots of white oaks and willow oaks (acorn producers) as the hedgerows. We had a deer hunt a few years ago and 36 guys killed 70 deer on a drive. Whatever we are doing is creating a deer paradise. They sure as heck eat the beans and corn but the damage we suffer to the wheat and barley isn't as great. Something eats up the acorns in a hurry but I don't know if it's just the squirrels and turkeys. Our only wildlife food plots have lespedeza and partridge pea for quail, and the deer population boom predates those plots.
When I say "corn" I mean feed corn, the big yellow hard oil corn, not the stuff for grocery stores.
