This is a more natural way to feed deer and will reduce the amount of daily maintenance your feeding project will require. You'll also be helping the environment! Apple trees, maple trees, and aspen trees all make great food for deer, so consider planting some of those trees on your property. Getting involved with your local wildlife agency will allow you to help deer and other local wildlife the best way possible. Dealing with professionals is a great way to make a difference and actually help animals, long term. If you live on hunt-able land, allow hunters to use your land during hunting season. Many rural areas are overpopulated with deer, which is why they face food shortages. Hunting keeps deer populations in balance with their available habitat, and minimizes the negative impacts on deer habitat, farmers, residents, and motorists.

Summary:
Consider planting trees to feed deer. Get involved with your local wildlife agency. Allow hunters on hunt-able land.
