Many gardeners, however, still feel the need to move along the all natural approach when it comes to keeping deer and other animals from turning their plants into dinner. The recipes for the natural deer repellents are varied in their ingredients but all have one common thread in that they create a bad taste for the animals.

There are other ingredients that the gardener will find a lot less offensive but will still be very effective.

This will create and incredibly bad taste in the animals mouths when used in the right amount and also assault their sense of smell. All this is done with a much lower offense factor to the gardener or property owner.
Garlic and onions can also help to serve the same purpose, either by adding them to the mix or simply planting them in the area. There are also garlic clips available for purchase that can be hung around the area, creating an invisible wall of odor to ward off the deer. All these methods work quite well on a variety of deer and are easily found by searching out the recipes online.
