Crepe myrtles are a popular choice for many landscapes, admired for their vibrant summer blooms and attractive bark. A frequent question among gardeners, particularly those in areas with deer populations, concerns how these elegant plants fare against browsing. Understanding deer behavior and plant vulnerability helps in maintaining healthy, thriving crepe myrtles.
Do Deer Eat Crepe Myrtles?
Crepe myrtles are generally considered deer-resistant, meaning they are not a primary food source. However, “deer-resistant” does not mean “deer-proof.” Deer will browse on crepe myrtles, especially when other palatable food options are scarce. This can occur during periods of drought, severe winter weather, or in areas with high deer populations where competition for food is intense.
Deer typically target tender new growth, leaves, and sometimes the bark. Young, newly planted crepe myrtles are particularly vulnerable as their tissues are softer and more appealing. While established plants with woody stems can often withstand some browsing, severe or repeated damage, especially to young plants, can stunt growth or potentially be fatal. Rutgers University’s rating system places crepe myrtles in the “seldom severely damaged” category, indicating that significant harm is uncommon.
Factors Influencing Deer Browsing
Several factors increase the likelihood of deer browsing on crepe myrtles. Hunger levels play a significant role, as deer are more inclined to eat plants they typically avoid when primary food sources are limited. This often arises during harsh winters when natural forage is buried under snow or during extended dry spells that reduce vegetation.
The availability of other food sources also influences deer behavior. If a landscape offers few palatable options, deer may turn to crepe myrtles out of necessity. While some variations in deer appeal exist between different crepe myrtle varieties, this factor is less significant than overall hunger or lack of alternative food. Browsing may become more prevalent in late winter or early spring when new vegetation has not yet emerged.
Protecting Crepe Myrtles from Deer
Protecting crepe myrtles from deer involves a combination of strategies. Physical barriers offer a reliable defense, particularly for young plants. Temporary fencing, such as wire cages around individual plants, effectively prevents deer access. For persistent issues, taller, permanent fencing, at least 8 feet high, may be necessary to exclude deer from a garden area.
Deer repellents are also effective, working by emitting scents or tastes deer find unpleasant. These repellents are available in various scent or taste formulations. Consistent reapplication, especially after rain or every few weeks, is important for efficacy, and rotating between different types can prevent deer from becoming accustomed to one. Strategic plant placement can also help; planting crepe myrtles closer to a home or in areas with frequent human activity may deter deer. Selecting varieties less favored by deer and regularly inspecting plants for signs of browsing allows for early intervention, minimizing damage.
