Deer Damage to Trees and Landscaping

One of the most frustrating things to deal with this time of year is having a deer snack on your beloved plants. Even if you are the type of person to tolerate deer damage because you love them, beware! Deer are creatures of habit. Once they feel safe and find a tasty snack, they will visit regularly.

An increase in deer populations and a decrease in their natural habitat have set up a situation in which your favorite landscapes become alternative food sources for deer.  As winter approaches and food sources become scarce, feeding on leaves, stems, and buds of plants becomes more apparent. Male deer also cause damage by rubbing their antlers along the trunks of trees, stripping off the bark. Trees and shrubs can suffer permanent damage. Deer should always be discouraged immediately.

deer damage to tree

There are four ways to discourage deer: Fencing, repellents, predators, and deer-resistant plants. 

Fencing requires you to enclose your entire yard with a fence at least six feet tall. This is not necessarily an aesthetically pleasing option, nor is it cost-effective. In some cases, you can put barrier fencing around these individual plants. While it is still unsightly, protecting a tree while it is young is important. 

Homemade and commercial repellents are common control methods to discourage deer, but their effectiveness varies. Snow and rain can wash them away, so frequent applications are needed. Also, if food sources are scarce, deer may simply ignore the repellents, despite the taste or odor.

As far as predators go, a noisy dog is an excellent deer deterrent. If you don’t have a dog, you can hang shiny tape from branches, or place inflated balls and other moving objects in the yard to startle the deer with sudden movement. You’ll have to rotate these frequently, however, or deer will soon realize that they are not in danger from these objects.

If they are hungry enough and food is scarce enough, deer will eat almost anything. However, there are a number of plants that deer don’t find particularly palatable. Using these plants in your landscape is often the most cost-effective, least time-consuming, and most aesthetically pleasing solution.

Below is a list of trees and shrubs not favored by deer. However, the resistance of any plant species may change due to environmental factors.

Always check to make sure that a plant is not invasive to your area before you plant it!
