Deer are becoming an increasingly severe nuisance for gardeners in several areas. The damage that they cause to ornamental plants from their browsing can be substantial-ranging from light pruning on tender shoots to heavy feeding of evergreen hedges, destroying their shape.
Deer are very adaptable creatures and, although they have their favourite plants, they will feed on almost any plant, especially during snowy winters when natural vegetation is covered. Several methods can be tried to minimize damage to the home garden in areas where deer are prevalent

REPELLENTS
Repellents can be effective, but usually for short periods of time. Multiple applications are often necessary, depending on how much rain falls and how hungry the deer are. Commercial repellents such as Thiram are available. Home-made repellents can also be effective-bars of soap hung in branches, human hair, dried blood (Blood Meal) and hot sauces are among the more popular methods which have been tried.
Homeowners often come up with ideas that are unique to their situations. Motion-sensing scare devices will sometimes work. Deer will adapt to almost any situation short of a fence, so it’s best to try different ideas to keep them off their guard.
