Dogs are sometimes used to help scare deer away. Also, frightening devices such as propane cannons, radios, and other noise-makers may work for a brief time. However, deer will acclimate quickly to a pattern of noise. Therefore, it is best to move frightening devices around every few days. Considering Deer Food Preferences Rearranging the plants will hinder deer.
Deer are picky eaters and they have an order of preference for eating plants.
Place plants with the lowest preference along the edges of the nursery where most problems occur. Increase the distance between the woods and the nursery to decrease deer problems. Or grow plants that deer do not like to eat. Some nurseries have taken the opposite approach. By accident, nurseries were planting crimson clover in the mid-rows of their trees.
