Pomegranate trees, with their vibrant blossoms and distinctive fruit, have become a favored addition to many gardens. Their unique beauty and the appeal of harvesting fresh, ruby-red pomegranates make them a popular choice for home growers. However, as with many desirable garden plants, concerns often arise regarding local wildlife, particularly deer, and their potential impact on these trees.
Pomegranate Trees and Deer Interaction
Pomegranates are often categorized as somewhat deer-resistant due to the slightly bitter taste and tough texture of their leaves. However, deer will still consume them, especially when other food sources are scarce, such as during dry seasons or winter. It’s important to remember that “deer resistant” does not mean “deer proof.” Young, tender growth and new shoots are particularly vulnerable. Deer might also eat the fruit and, in winter, can girdle trees by eating bark, which can severely damage or kill the plant.
Identifying Deer Damage on Pomegranates
Recognizing deer damage is important for effective protection. Deer lack upper incisors, so they grasp and tear plant material, leaving ragged, torn, or shredded edges on leaves, twigs, and branches. This ragged appearance differentiates deer browsing from cleaner cuts made by other animals like rabbits or rodents.
Deer browsing often occurs up to 6 feet from the ground, indicating the reach of an adult deer. “Browse lines,” where vegetation below about 4 feet is stripped, are another common sign. Male deer also damage trees by rubbing their antlers on trunks, especially in fall, creating vertical scrapes or shredded bark that exposes the inner wood. Additionally, finding deer droppings (small, oval pellets) or heart-shaped hoof prints (2-3 inches long) near damaged plants confirms deer activity.
Protecting Pomegranate Trees from Deer
Implementing a combination of deterrent methods often provides the most effective protection for pomegranate trees. Physical barriers are highly reliable, with fencing being a primary option. A fence at least 7 to 8 feet tall is generally necessary to prevent deer from jumping over. Wire mesh or netting can also be draped over individual trees. Burying the bottom of the fence can deter deer and other animals from burrowing underneath.
Repellents work by creating unpleasant tastes or odors that deter deer. Commercial repellents often contain ingredients like putrescent eggs, blood meal, garlic, or capsaicin. Homemade solutions using ingredients such as eggs, milk, dish soap, hot pepper, or garlic can also be effective. These sprays should be applied directly to the plant foliage, but care should be taken to avoid spraying fruit if it will be consumed. Repellents need reapplication, especially after rain, and rotating different types can prevent deer from becoming accustomed to one smell or taste.
Scare tactics capitalize on deer’s natural wariness of new or unexpected elements. Motion-activated sprinklers, which spray water when triggered by movement, can startle deer and discourage them from entering an area. Other methods include hanging reflective objects like old CDs, wind chimes, or noise-making devices that create unexpected sounds. Regularly changing the location or type of scare tactics helps maintain their effectiveness, as deer can quickly habituate to static deterrents.
