Wax myrtle (Morella cerifera), an evergreen shrub or small tree, is generally considered deer-resistant. While not entirely deer-proof, its aromatic foliage and specific leaf texture typically make it less appealing to browsing deer.
Why Deer May or May Not Eat Wax Myrtle
Wax myrtle’s foliage is highly aromatic, releasing a spicy, resinous fragrance from essential oils that are unpalatable to deer. Its waxy or leathery texture also contributes to its lack of appeal compared to softer, more tender vegetation.
Despite these natural defenses, wax myrtle is not completely immune to deer browsing. Deer are opportunistic feeders; while they generally avoid plants with strong odors, extreme hunger can override these preferences. Under environmental pressures, deer may still browse on wax myrtle, especially if other palatable food sources are scarce.
Factors Influencing Deer Browsing
Several external factors influence whether deer browse on wax myrtle. High deer population density can lead to increased browsing pressure on plants not usually preferred. When food is limited, deer may resort to less palatable options like wax myrtle. This overpopulation can significantly impact forest vegetation, reducing diversity as deer consume nearly everything.
The availability of other food sources plays a significant role; if preferred forage is scarce due to drought, harsh winter conditions, or overgrazing, deer are more likely to turn to plants they would normally avoid. Young, tender wax myrtle plants might also be more susceptible to browsing than established, mature ones, as their new growth can be softer and potentially less aromatic. Individual deer can exhibit varying food preferences.
Protecting Wax Myrtle from Deer
Protecting wax myrtle from deer involves a combination of strategies. Physical barriers, such as fencing, are effective. A deer fence should be at least 7 to 8 feet tall to prevent jumping and secured at the bottom. Netting made of polypropylene mesh or wire can also be used, with some kits including adjustable poles and sod staples for installation.
Deer repellents can also be applied to wax myrtle to deter browsing. These products typically work by taste or odor, making the plant unappealing. Some homemade repellents involve strong-smelling ingredients like garlic, hot peppers, or an egg and milk solution, which can be sprayed directly onto the foliage. The effectiveness of repellents can vary, and reapplication is often necessary, especially after rain, as deer can become accustomed to them over time.
Strategic planting can further reduce deer damage. Placing wax myrtle near areas with regular human activity, such as close to a home, can deter deer, as they tend to avoid busy spaces. Companion planting with other deer-resistant plants, particularly those with strong odors, can also help mask the scent of more vulnerable plants and make the area less attractive. Regularly monitoring plants for signs of browsing, such as ragged edges on leaves or twigs, allows for timely intervention and adjustment of protection methods.
