Deer Feeding Habits
Deer feed selectively on fertilized and unfertilized landscape plantings and managed croplands. Costly browsing damage may be reduced or eliminated by planting less-preferred species or by establishing susceptible plants only in protected areas. A few strategies to consider include planting susceptible plants close to the house or in a fenced yard, or planting preferred species inside a protective ring of less-preferred species. Under most circumstances, landscaping based on a knowledge of deer feeding preferences provides an alternative to expensive chemical repellents and unsightly physical barriers.

Whether deer will target a particular plant species or variety depends on their previous habits and nutritional needs, plant palatability, seasonal factors, weather conditions, geographic area, and availability of alternative foods. Deer are creatures of habit, and previous movement patterns or foraging experiences can determine where damage will occur. Also, one plant species may be rarely damaged in one region or the country, but highly preferred in another due to differences in deer pressure and other factors. Examples of species with noted regional differences include holly, white pine, and deciduous magnolias. Therefore, caution must be taken when using plant preference lists from areas outside your own.

In general, damage from browsing is most severe when snow cover or extreme cold has reduced food availability. Another problem time is early spring when young succulent growth of ornamentals provides attractive browse before other spring growth is avialable. When food is in short suply, deer will browse even the most undesirable plants. Under such conditions, landscapers should combine damage control measures with careful plant selection. Damage control measures could include repellents, physical barriers (fencing), and deer population control. Ultimately, reducing the deer herd size is the most effective solution.
