Stargazer lilies, with their striking, star-shaped blooms and intoxicating fragrance, are a cherished addition to many gardens. Known for their vibrant colors and suitability as cut flowers, they create a dramatic visual appeal. A common concern for those growing these plants, however, involves local wildlife, particularly deer.
Are Stargazer Lilies Deer Resistant
While some sources might suggest Stargazer lilies possess deer-resistant qualities, these plants are generally not considered immune to deer browsing. Deer are opportunistic feeders, and if other food sources are scarce, they will readily consume a wide variety of plants, including lilies. Their attraction to Stargazer lilies can stem from their palatability, high water content, and tender foliage, especially new growth.
Deer are drawn to gardens that offer easily accessible and nutritious forage. Areas with dense deer populations or limited natural food can increase the likelihood of Stargazer lilies being targeted. Even plants typically avoided by deer might be consumed under pressure, meaning lilies frequently fall victim to their browsing habits.
Recognizing Deer Damage
Identifying deer damage on your Stargazer lilies involves looking for specific patterns that differentiate it from other garden pests. Deer lack upper incisors, causing them to tear and rip plant material rather than making clean cuts. This results in ragged, shredded, or torn edges on stems and leaves. If you observe jagged edges or a general disheveled appearance on your lilies, deer are likely the culprits.
Deer browsing often occurs higher up on the plant, as deer can reach foliage up to six feet from the ground. In contrast, rabbits typically make clean, angled cuts closer to the ground. Additional signs of deer presence include distinctive heart-shaped hoof prints, typically 2 to 3 inches long, in soft soil or mulch. Oblong, pellet-like droppings, often found in piles near feeding areas, also indicate deer activity.
Protecting Your Stargazer Lilies
Protecting Stargazer lilies from deer requires a multi-faceted approach, combining various deterrent methods.
Physical barriers
Physical barriers offer effective solutions to prevent deer from accessing your plants. Fencing should be at least 8 to 10 feet high to deter deer, as they are capable jumpers. In wooded or more obstructed areas, a 6 to 8-foot fence might suffice, but open spaces necessitate greater height. Installing a double fence with two parallel fences spaced a few feet apart can also confuse deer due to their limited depth perception, making them less likely to attempt a jump. For individual plants or small beds, netting can provide a temporary physical barrier, safeguarding vulnerable new growth.
Deer repellents
Deer repellents utilize taste or scent to make your lilies unappealing. Scent-based repellents, often containing ingredients like rotten eggs, garlic, or predator urine, deter deer through their strong sense of smell. Taste-based repellents make the plant unpalatable, using bitter or spicy substances. Commercial repellents typically require reapplication every 2 to 4 weeks, or more frequently after heavy rain or during periods of new plant growth, to maintain effectiveness. Homemade options, such as mixtures of eggs and water, or garlic and hot pepper with dish soap, can also be used, though they often need more frequent reapplication.
Strategic planting
Strategic planting involves positioning Stargazer lilies within a garden layout that makes them less accessible or attractive to deer. While no plant is entirely deer-proof, interplanting lilies with species deer typically avoid due to strong fragrances, fuzzy textures, or bitter tastes can offer some protection. This method can reduce the initial appeal of the area, though a hungry deer may still bypass less palatable plants.
Motion-activated deterrents
Motion-activated deterrents can startle deer, discouraging them from lingering in your garden. Motion-activated sprinklers deliver a sudden spray of water, while devices emitting ultrasonic sounds or even playing a radio station can create an unsettling environment. Rotating the placement of these devices or changing their settings can prevent deer from becoming accustomed to them. Hanging reflective items like old CDs or shiny ribbons can create unexpected flashes of light that may deter deer.
Cultural practices
Cultural practices also contribute to deer deterrence by making your garden less inviting. Regularly cleaning up fallen leaves, fruit, and other garden debris can remove potential food sources or hiding spots. Keeping your lawn well-manicured and trimming tall grasses can make your property appear less like a natural foraging ground. These consistent efforts, combined with physical barriers and repellents, can significantly reduce deer damage to your Stargazer lilies.
