Keep Your Landscape Deer Free

Keep Your Landscape Deer Free

In some neighborhoods, deer damage to ornamental plantings peak in winter when snow cover reduces the food supply. Deer will eat almost any plants in front and backyard plantings. Damage control measures and careful plant selection can help keep your landscape deer free.

“Deer are selective feeders that eat leaves from flowers, shrubs and ornamental trees,” explains Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association. “Damage to larger trees can extend up to 7 feet off the ground.”

Damage Protection

A fence is the most effective control against deer damage. An 8-foot fence is generally sufficient to deter deer, and lower fences can work if they slant away from your yard. Tree protectors or shelters also prevent deer from browsing on young trees. Made of polypropylene tubing, plastic tree wrap or woven-wire mesh cylinders, netting can be used to protect individual or group plantings. The netting can be left on year-round if it’s attached loosely at the base to allow for plant growth, but should be monitored frequently.

Repellents may help deter deer, but they do not eliminate damage completely. Homemade repellents include rotting eggs (mix two eggs with a gallon of water and spray the mixture on ornamentals). The eggs rot on the plants and the smell repels deer. Human hair hung in mesh bags makes a simple repellent. Hang the hair bags on the outer branches of trees about a yard apart, and replace them monthly. Bars of strong-smelling soap hung in the same way will also work. This is a good way to make use of all those aromatic Christmas gift soaps you don’t plan to use. Repellents containing predator urine or spray-on, soap-based mixtures usually only last a few weeks, depending on the weather.

Best Trees

Once deer taste your landscape, it’s difficult to rid them of the habit. Replacing your current mix of trees and shrubs with plants that are less appealing will help move the herd along to other sites. The Tree Care Industry Association recommends planting trees that have a history of surviving areas of heavy deer activity, such as:

  • Bottlebrush buckeye
  • downy serviceberry
  • shadbush
  • Allegheny serviceberry
  • pinion pine
  • Chinese paper birch
  • ‘heritage’ heritage birch
  • paper birch
  • Japanese false cypress
  • Japanese cedar
  • Colorado blue spruce

Best shrubs and Climbers

Larger, tall shrubs tend to withstand deer browsing better than low-growing ones because they have more leaves, making them able to withstand some defoliation, and taller plants are out of reach.

Try these shrubs:

  • bearberry
  • pawpaw
  • boxwood
  • caryopteria
  • American bittersweet
  • red osier dogwood
  • Japanese plum-yew
  • creeping wintergreen
  • John T. Morris holly
  • Lydia Morris hollies
  • leucothoe
  • European privet
  • Japanese andromeda
  • Virginia creeper
  • blueberry elder
  • dwarf sweet Christmas box
  • rose of Sharon

Check with your local garden center or tree care company for a list of trees and shrubs in your area that are the least appealing to deer.
