The Crape Myrtle (Lagerstroemia indica) is a beloved feature in many landscapes, prized for its impressive summer blooms and attractive exfoliating bark. As residential areas expand into natural habitats, a common concern arises: whether this popular shrub will become an easy meal for local deer populations.
The Palatability of Crepe Myrtles
Crepe Myrtles are generally classified as “deer resistant,” meaning they are rarely a preferred food source. This resistance is attributed to the plant’s texture and taste, which make it unappealing to browsing animals. For instance, the flowers have a papery texture, and mature foliage is not typically included in a deer’s primary diet.
The Rutgers University rating system, often used by gardeners, places the Crape Myrtle in the category of plants “seldom severely damaged” by deer. This high level of resistance makes it a favorable choice in areas with high deer traffic. While the plant is resistant, it is important to understand that no plant is entirely “deer-proof,” and a starving animal will eat almost anything to survive.
When Deer Are Most Likely to Browse
Deer activity and feeding habits are closely tied to environmental conditions and the availability of preferred forage. The natural resistance of the Crepe Myrtle is most likely to be overridden during periods of extreme food scarcity. This pressure is often greatest during the late fall and winter months, typically from October through early spring, when other deciduous foliage is absent.
When the deer’s preferred food sources are scarce, especially during drought or heavy snow, they will turn to less palatable plants, including Crepe Myrtles. Young shrubs and tender new growth are also particularly vulnerable to browsing, even in the spring when other food is available. New leaves and stems often contain higher levels of nitrogen, making them a more nutritious and attractive target for developing fawns or does feeding their young.
Implementing Effective Deer Control
Protecting Crepe Myrtles from the occasional browse requires a multi-pronged approach that combines physical barriers, repellents, and strategic planting. Physical exclusion is the most reliable method, especially for young or newly planted shrubs that are highly susceptible to damage. Temporary fencing, such as wire cages or netting, can be placed around individual plants to prevent browsing while the plant establishes a woody stem.
For a more permanent solution across an entire property, a perimeter fence should be installed at a height of at least seven to eight feet, as deer can easily clear lower barriers. Alternatively, a double fence system, consisting of two lower fences spaced several feet apart, can confuse the deer’s depth perception and prevent them from jumping the enclosure.
Repellents target the deer’s strong sense of smell and taste, discouraging them from feeding on treated foliage. These products fall into two categories: scent-based repellents (often containing putrescent whole egg solids or garlic) and taste-based repellents (which may include capsaicin or ammonium soaps). To maintain effectiveness, repellents must be rotated regularly to prevent deer from becoming accustomed to a single formula.
Reapplication is necessary every two to four weeks, or immediately after heavy rainfall, to ensure the protective coating remains on the plant. Cultural practices can also make the landscape less appealing to deer. Planting Crepe Myrtles closer to the house or in areas with frequent human activity provides a deterrent. Interplanting them with strongly scented, unpalatable species like lavender or ornamental sage can help mask the Crepe Myrtle’s scent. Motion-activated sprinklers or noise-making devices provide an element of surprise that deer prefer to avoid.
