Deer Activity: How to protect your trees from deer

Resources: Tree Problems

Due to recent snows, deer activity appears to be more prevalent in Virginia. Unfortunately, a result of this deer activity is more deer left for dead on our highways and side roads as they migrate from one place to another. In congruence with their heightened activity is the need for shelter and warmth. More often than not, trees are on the receiving end of this and end up damaged or in irreversible decline. 


What does deer damage look like to my trees?

Rutting 

During fall male deer are looking to clean their antlers of summer velvet, while at the same time marking territory during the breeding season. They achieve this by rubbing their antlers against trees to remove the velvet and by thrashing and battering the tree. When deer rub their antlers against the tree it removes the tree’s cambium. 

Cambium is the layer between the bark and the wood that helps transport nutrients through the tree. When the tree’s cambium is severely damaged the tree is at risk of dying. Young trees, especially those 1 to 4 inches in diameter with smooth bark, such as maple, magnolias, and birch, are especially susceptible to rutting. Because this is also a territorial action, the buck may revisit trees they like in subsequent years.

How to deter deer from rutting 

The easiest way to stop deer from rubbing their antlers on your tree is to put up a physical barrier. You can accomplish a physical barrier in a few ways. One of the most expensive and involved ways is to put up protective fencing around your yard. This would mean a fence that is 6 feet tall that deer can not jump over or get through. However, this isn’t feasible or realistic for many homeowners and luckily there are cheaper and easier options. 

The easiest option is for homeowners to purchase wire or plastic tree guards that wrap around the base of the tree. You can also make your own tree guards by using chicken wire just make sure the wire is taller than your average buck. SF Gate suggests the height of tree guards should be 4-5 feet tall for full protection. 

Feeding on Foliage 

During the fall and winter food can be scarce for deer. When the food supply is low, deer will wander into your yards and gardens and feast on your plants, trees, and shrubs. Although deer browsing may not sound like that big of a deal the damage can be extensive. Deer feeding on foliage can affect the plant’s shape and ability to feed itself through photosynthesis. 

Euonymus (also called spindle, burning-bush, strawberry-bush, wahoo, or wintercreeper) is a favorite target of deer. Hosta (Host sp.), Candy Lily (Pardancanda x norrisii), Roses, Yews (Taxus sp.) American Arborviate (Thuja occidentalis), Evergreen Azaleas & Rhododendron (Rhododendron sp) are also high on the favorite food list for deer. If you have any of these species you may see more instances of deer feeding in your yard. 

How can I  protect my trees from deer?

The trick to keeping deer from eating your shrubs is to make these usually tasty feasts taste terrible. We do this through treating the shrub’s foliage with a special product that makes your shrubs taste bad. The next time the deer wander onto your property for a snack, they will go in for a taste but quickly find out that what looks like their favorite meal tastes horrible. Discouraged they will move on to the next tasty plant in the vicinity (usually your neighbor’s plants unless they get deer protection as well.)

This treatment is safe and not harmful to your plants/shrubs. However, it is not advised for Blue spruces otherwise their blue tint will be removed.


If you already have deer damage on your tree, sadly,  it can not be reversed. However, if you properly maintain your tree and give it the love it needs, the tree may be able to recover, depending on the extent of the damage. Our Arborists suggest 

  • Bio-stimulants, 
  • Preventative Disease/ Insect Treatments,
  • Proper watering, 
  • Aeration, and
  • Regular pruning to help your tree recover from deer damage.

We have been using RTEC for years and were very pleased with the recent tree maintenance work they did for us. As always, we got good advice from their arborist Ben,. The crew that did the work is highly skilled, and they did a great job trimming our trees. They worked safely and efficiently, in addition to leaving the yard clean after they finished the work.

RTEC was at my house today to removed a large Magnolia that was badly damaged by the recent snow. They did a fantastic job at a very reasonable price. They arrived right on time, worked efficiently and quickly and cleaned up so well it was hard to tell anything have been disturbed. Over the past several years, I have used RTEC for all the services I checked above, and have always been very pleased with their service and professionalism. I also appreciate that they are not eager to take down trees that don't need to come down. In this case, the damage was too extensive for the tree to recover.

Once again, RTEC has done a great job. The team showed up right on time and performed all the work that we agreed to. They kept us informed as to progress, coordinated with us concerning our maple, and made recommendations concerning ongoing support for our trees. At the end of the day, they thoroughly cleaned up the debris and left our yard in pristine condition. WELL DONE.

Not our first time but this time was tricky removal of a large dead tree leaning on a healthy tree. Quick response for estimate, good timing to removal, all clear and healthy tree still fine.

We’ve used RTEC for many years for tree maintenance and can’t say enough good things about their service. We use them for tree trimming and for regular treatments to maintain our trees’ health and deal with pests and prevent disease. Their arborist Ben has been especially helpful with advice. RTEC also been especially helpful in emergency situations, once coming to cable a massive, heritage oak in our yard right before a hurricane was about to hit. Highly recommend.

RTEC did an excellent job onsite of removing dead branches from our 80+ year old trees, and trimming other growth too close to our home.
