How to keep deer from eating shrubs comes down to a few tools that extension services rank differently: physical exclusion, protective wraps, repellents, and choosing plants deer tend to avoid. Two university extension publications, one from the University of Connecticut and one from Utah State University, describe these methods in detail. Both say that fencing is the most dependable option, and both say that no single method works on every shrub in every season.
Quick answer
- Fencing is the most reliable method. Utah State says fences provide “the most reliable method for controlling deer damage,” and UConn gives a height and gap standard for keeping deer out.
- For single shrubs, wrap them. Utah State suggests burlap, layered plastic or snow fencing, and says the wrap must come off at the end of winter.
- Repellents work only while they are maintained. UConn says to reapply them as new growth emerges and after rain.
- Plant choice reduces risk without removing it. UConn states that “no plant is completely deer proof.”
Why deer browse shrubs
Deer do not eat landscape shrubs at random. UConn Extension says that deer “usually visit areas where they feel safe and can smell that other deer have visited,” and that they come to residential areas “most often in winter, when forest food is in short supply, and in spring, when new growth is most tender and tasty for them.” It adds that deer “especially enjoy eating young flower buds and well-watered or well-fertilized plants.”
Utah State Extension describes a similar pattern in mule deer. It says that “in winter, deer often browse in residential landscapes,” and that natural winter browse “may be less available than in the past” because traditional winter range has been replaced by pavement, homes and cultivated landscapes. The same source notes that damage can also occur in summer, “particularly during droughts when some native plants are water stressed and become toxic.”
Deer also damage shrubs and young trees in a different way. Utah State says that “in the fall, male deer often rub their antlers against trees to remove the velvet layer that coats them,” and that this “can cause large scars on trunks and branches and can cause permanent damage.” UConn notes that deer sometimes strip bark off small trees and branches or injure plants by rubbing antlers on young trees.
Fence the plants that matter most
Fencing is the method both sources rank highest. Utah State says “10 foot tall fencing should be installed around sensitive areas,” and that it should be “tight to the ground so that deer cannot crawl underneath.” It also says that positioning a fence “outside the canopy edge of low-branching hardwoods or just beyond the bottom branches of conifers will prevent most damage.” Utah State lists the benefit that a fence “can protect plants from deer damage for many years, assuming gates are closed and fences are maintained.”
UConn gives a slightly different standard. It says that “deer can jump, so fences must be at least 8-feet high, with no more than 6-inch by 6-inch gaps, and must reach the ground.” The two heights differ. The 10-foot figure from Utah State and the 8-foot minimum from UConn are both given in their sources, and a gardener in a deer-heavy area may choose the taller fence. Both sources list cost and appearance as drawbacks. Utah State says that “construction and maintenance costs may be prohibitive” and that fencing “may not be aesthetically pleasing to you or your neighbors.”
UConn also suggests a zoning approach. It says to “divide the landscape into zones” and to “place the most deer resistant plants along the far edge of the property.” Plants most likely to be eaten should be close to frequently used entrances or grown within a fenced area. This keeps the most valuable shrubs inside the protected part of the yard.
Wrap or protect single shrubs and trunks
For a few plants, a physical barrier may be easier than a fence. Utah State says that browsing deer can be discouraged by wrapping “individual shrubs with burlap, layered plastic or inexpensive snow fencing.” It rates this as affordable, quick and effective, and notes two drawbacks. Many shrubs take time to wrap, and “you must unwrap shrubs at the end of the winter to allow for healthy plant production.”
Trunks and young trees can be protected with tubes or cylinders. Utah State says that “tree protectors are affordable and effective at inhibiting deer damage to tree bark,” and that they can be left on year-round if they allow normal tree development. It warns that with small trees, “the deer may just push over the entire protector and tree,” and that a protector can be so tight that the foliage and stem do not develop normally. UConn recommends “wire-mesh cylinders that surround the trunk” to discourage feeding and rubbing.
UConn also mentions fishing line. It says that “fishing line strung around specimen plants is an easy and inexpensive way to confuse and push away deer.” The source does not say how long the line remains effective, so check it regularly.

Repellents and deterrents
Repellents work by taste or smell. UConn describes them as “products that discourage deer from feeding because of an unpleasant taste or odor.” Its instructions are specific. The repellent should cover “the plant from the ground level upward to at least six feet,” and it should be “reapplied on a regular basis as new growth emerges and after rainfall.” Utah State describes repellents as a way to “temporarily protect plants,” which fits this maintenance pattern.
Motion-activated sprinklers, lights and noisemakers can also help, according to UConn, but the source warns that “success with these type of deterrents is typically short-lived.” Deer become accustomed to devices that are not moved or changed in pattern. The source recommends moving or altering the devices so that deer remain “constantly wary.” Neither extension source gives a specific product recommendation, and this guide does not name any.
Choose shrubs deer tend to avoid
UConn lists plants that deer tend not to eat, and it describes the general traits. It says deer avoid plants “with thorns or prickles on leaves or stems,” “with strong scents and bitter flavors (ex. herbs),” that “are poisonous or have thick sap,” and that “have hairy or fuzzy leaves.” The same list treats ornamental grasses and ferns as highly resistant to deer damage.
Some shrubs from the UConn list are shown below. The list is from a Connecticut publication, so check local recommendations before planting.
| Shrub (as listed by UConn) | Scientific name in source |
|---|---|
| Bayberry | Morella/Myrica pensylvanica |
| Boxwood | Buxus sempervirens |
| Chokeberry, red | Aronia arbutifolia |
| Pieris, Japanese | Pieris japonica |
| Eastern red-cedar | Juniperus virginiana |
UConn is clear that deer-resistant does not mean deer-proof. It says that “young deer do not know which plants taste good until they sample,” and that deer will eat almost anything to survive when their preferred foods are not available. Plant choice works best with fencing or wraps for the shrubs that are most valuable.
Adjust fertilizer and watering
UConn advises using less fertilizer where deer visit often. It says that “deer favor lush, well-fertilized plants, but may avoid the same plants if they are less appetizing.” This is a trade-off, because a shrub that is fertilized less may also grow more slowly. The source also notes that deer prefer well-watered plants.
What the sources say about deer populations
Utah State reports that the Utah Division of Wildlife Resources is aware of the urban deer problem. The source quotes a DWR biologist who says that “deterring mule deer from browsing on shrubs and trees in our yards likely will not cause them to starve over the winter,” because deer will find other food. The source’s point is that protecting a shrub is unlikely to starve the deer, because they can find other forage.
UConn describes a broader pattern. It says that deer populations have grown in the United States over the last 100 years, and that fewer predators and wooded areas have fueled their growth in urban and suburban areas. The source’s key point is that deer can be trained to avoid residential locations if the area seems unsafe and the food is unappealing.
How we chose these sources
We chose two university extension publications that describe deer damage to shrubs and give specific prevention methods. The UConn Extension publication, “Preventing Deer Damage in the Home Landscape” by Vickie Wallace and Alyssa Siegel-Miles (August 2016), covers white-tailed deer in the Northeast. The Utah State University Extension fact sheet, “022 – Preventing Deer Damage to Your Trees and Shrubs,” covers mule deer in the Intermountain West. Both were opened on 2026-10-27, and quotations come from the text returned on that date.
The two sources cover different species and regions, so their advice has been kept separate where the details differ. Fence height and deer behavior are the main differences. Where a claim comes from only one source, the text says which one.
What we could not verify
The sources describe methods and their trade-offs. They do not measure how effective each method is on a particular property, and they do not give a success rate for repellents, fences or wraps in a specific neighborhood.
What the sources do not say
Neither source names a brand of repellent, a fence material, or a sprinkler model, and this guide does not add one. UConn does not give a reapplication interval in days, saying only “on a regular basis” and “after rainfall.” Utah State does not say how many years a fence will last. The sources also do not describe how effective the plant lists are for the specific shrub varieties sold today. Local extension offices can help with those details.
Frequently asked questions
How tall should a deer fence be?
UConn says fences must be at least 8 feet high, with gaps no larger than 6 by 6 inches, and that they must reach the ground. Utah State says 10-foot fencing should be installed around sensitive areas. The taller figure is the more cautious one in the sources.
Do deer repellents work all year?
UConn says repellents must be reapplied on a regular basis as new growth emerges and after rainfall, which means they need ongoing attention. The source does not say how long a single application lasts.
Will wrapping a shrub hurt it?
Utah State says the wrap must come off at the end of winter to allow healthy plant production, so plan to remove it in spring.
Are deer-resistant plants completely safe from deer?
No. UConn says that no plant is completely deer proof, because young deer do not know which plants taste good until they sample them, and deer will eat almost anything when preferred food is scarce.
Will keeping deer away from shrubs starve them?
Utah State quotes a Utah DWR biologist who says that deterring mule deer from shrubs and trees in yards likely will not cause them to starve, because they will find other food.
