According to Jeff Jackson, UGA Wildlife Biologist, one deer can eat 4 pounds of woody twigs in a day. That's about 120 pounds a month. And according to some research from Michigan's George Reserve, two bucks and four does produced a heard of 160 descendants in just 6 years. Nuisance deer are difficult to control in residential communities. There are a number of commercially available repellents on the market, but they wash off with rain and must be re-applied.
Most home remedies are also unreliable and many are unsafe.
Shooting is often prohibited. That leaves us with just two options - planting things that deer do not like to eat, and fencing. Planting deer-resistant ornamentals is one of the best ways to minimize deer browsing. However, remember that very few plants are totally deer-resistant. When deer populations are high and food becomes scarce, deer will eat just about anything.
