Yes, the One Great Truth about early-season deer food is that acorns rule. But deer eat like your kids do, gorging on one thing until they’re sick of it and then turning to something else. And in early fall, what they turn to is usually green. Think about it: Every food source in the whitetail world is drying down, and they’ve got the rest of winter to gnaw on twigs, so they go for the succulent stuff while they can, including still-green bean plants, alfalfa, wheat, rye, clover, peas, and brassicas. Even if there’s a good acorn crop, count on deer to chaw on nuts for a week, then turn their attention back to greens.
