Deer may be lovely to look at, but they are decidedly not so lovely when they get into your garden and eat the leaves and flowers off your plants. There are several ways to keep deer out of your garden without harming either the deer or your plants. With diligence on your part, these methods do not take a lot of effort. It's essential that you check your garden regularly, though, even with these methods in place.
Make a spicy deer repellent using hot sauce, eggs and garlic. The smell of the spices will keep the deer at bay and the egg will help the mixture stick to the plants. Crack two raw eggs and stir them into a bowl filled with 2 tablespoons of minced garlic and 2 tablespoons of any generic red hot sauce. Pour the mixture into the blender and blend on high. Add lukewarm water as needed until the repellent is thin enough to dispense using a spray bottle. Spray it on all the plants in your garden once every two weeks.
Make a soapy deer repellent. It will feel uncomfortable on the deer's legs and tongues. Add a gallon of lukewarm water to your garden sprayer. Mix in one raw egg, a half cup of milk, 1 tablespoon of unscented dish soap (without bleach) and 1 tablespoon of olive oil. Put the top on the sprayer and swirl or shake it until all ingredients are mixed together. It helps to whisk the egg yolk before pouring it in. Spray it on all the plants in your garden once every two weeks.
Scare deer by placing bloodmeal, which is a common nitrogen-based fertilizer available at many garden centers, in 2.75-inch-by-4-inch muslin bags. Hang the bags from shrubs and trees in your garden. For further repellent, add short pieces of human hair to these bags. Your local barber shop should be able to supply you with more than enough. This makes the deer think humans are close by and should keep them away.
Install propolyene deer fencing around the perimeter of your garden. Use fencing that is at least 8-feet tall to keep even the largest deer out. Place wooden fence posts at 3-foot intervals around the outside of your garden plot and staple the fencing to them.
