I've tried everything I've ever heard of to keep deer away from my plants. I finally found the only solution. Here's the recipe:
Whip up a raw egg and a cup of water in the blender. Pour that into a pistol grip one-quart spray bottle. Fill to the top with water, adding 1 tsp. dish soap. Set in the hot sun till putrified (about 3 days), and give a little squirt to those plants they love to eat. It doesn't take much either, just a small squirt. They absolutely hate it. But you must reapply after a rain. However, you will see your plants grow to fruition.
Source: I read some of the ingredients on a $17 bottle of deterrent at a hardware store and recognized albumen as referring to egg,so I invented my own $.10 version. The soap helps it stick to the plants.

I use a quart water, one egg yoke, one tablespoon of hot pepper flakes, one tablespoon baking powder, two cloves chopped garlic. Blend with wire wisk. Allow to sit overnight. Strain and spray on and around plants. Deters deer, groundhogs and rabbits. This really works.

Deer don't like eggs! This recipe is easy to make and fairly inexpensive, it calls for 18 eggs. You can also make small batches.
