Protecting Against Deer Damaged Trees

Return to Trees and Shrubs Agent Articles

Watching Bambi prance through the woods might be enjoyable to watch, but once this cute, furry little creature crosses the line there is going to be trouble. Deer damage is a problem in many backyards during the winter months. In fact, we are already getting reports of damage.

How deer damage trees
Bucks rub their antlers on young trees, causing extensive damage to the bark, which often results in a slow death for the tree. Protecting trees from damage is essential in areas populated with deer. Once the damage is done, there is little that can be done to repair the tree. Most times, the tree will need to be removed. It is recommended to protect all trees, deciduous and evergreen, under 6 to 8 inches in trunk diameter.

Odor deterrents
There are a number of products on the market that have a strong odor which deter the deer. They contain mixes of hot peppers, garlic and even urine smells to help keep the deer at bay. Deer repellents are usually not effective because they wear off with rain and snow. They should be applied at least once a month, or after every rainfall starting from early fall till late winter. Miss a timely application and the end result is damage. Best results may be achieved by alternating between products.

Tree wraps
This method uses a material made from paper or plastic that covers up the main trunk of a tree. Paper wrap is less effective as it can be worn through by the deer. Corrugated plastic tubing is a good option. But a word of caution: the friction caused by heavy rubbing can rip the bark. Tree wraps can be found at your local garden centers. Wrap the trunk, covering all exposed bark, from the base until you reach the bottom branches. Be sure to remove the wrap in late winter/early spring before the tree leafs out.

Fencing
The most effective method is to construct a rigid fence out and around the trees. Start by using three to four heavy-duty metal fence posts. Drive them into the ground at the dripline of the evergreen tree. For deciduous trees, put them 2 feet or more from the trunk. The fence posts provide a rigid object for the deer to rub against. You could stop there, or you could add another level of defense. For additional protection, wrap the fence posts with a woven wire. Concrete reinforcing wire or similar material works well. This encloses the tree and prevents the deer from getting to it.

Home remedies
There are a number of home remedies to keep deer at bay. These include hanging all types of odorous soaps or even human hair in the lower branches. The bottom line is they provided spotty control, at best. Best control is best achieved with one of the other recommendations.

Before cute cuddly Bambi destroys your investment, take action. You will not regret the time and effort, and your trees will also say “Thank you.”
