Foxtail ferns (Asparagus densiflorus ‘Myersii’) are popular ornamental plants known for their distinctive, plume-like foliage that resembles a fox’s tail. These evergreen perennials bring a unique texture to garden beds, containers, and hanging baskets, making them a favored choice for many landscapers. Gardeners often wonder about their susceptibility to deer browsing, a common concern in areas where deer populations are present.
Deer and Foxtail Ferns
Foxtail ferns are generally considered deer-resistant plants, meaning deer are unlikely to bother them. This resistance is primarily due to their texture and taste. The needle-like leaves and somewhat fibrous nature of foxtail ferns are typically less appealing to deer compared to other, more succulent plant options. Ferns, in general, may also contain compounds or toxins that deter deer from consuming them.
No plant is entirely deer-proof. A hungry or thirsty deer may browse on plants it would normally avoid. While foxtail ferns are not a preferred food source, they could still be nibbled on, especially during periods of food scarcity. The likelihood of significant damage to foxtail ferns remains low under normal circumstances.
Factors Influencing Deer Foraging Habits
Several conditions influence whether deer consume plants they typically avoid, including foxtail ferns. A primary factor is the availability of preferred food sources. When natural forage is scarce, such as during droughts or harsh winter months, deer become less selective and may turn to less palatable options in gardens, leading them to browse on foxtail ferns.
The density of the local deer population also plays a role; in areas with high deer numbers, competition for food intensifies, leading deer to explore a wider variety of plants. Individual deer preferences vary, with some being more adventurous eaters. Additionally, young, tender plant growth might be more appealing than mature foliage, even on deer-resistant plants. Deer foraging behavior is complex and can be influenced by factors like weather, social dynamics, and perceived predation risk.
Protecting Your Foxtail Ferns from Deer
Gardeners can employ several strategies to minimize potential deer damage to foxtail ferns. Physical barriers are highly effective; fencing at least 7 to 8 feet tall can prevent deer from jumping into garden areas. Netting or row covers can also provide direct protection for individual plants.
Deer repellents offer another layer of defense by making plants unappealing through scent or taste. Commercial repellents, often containing essential oils or other natural deterrents, are available and should be reapplied regularly, especially after rain. Homemade solutions, such as those with strong scents like garlic, peppermint oil, or soap, can also be effective.
Strategically planting companion plants that deer dislike, such as those with strong odors or fuzzy textures, around foxtail ferns can also help deter them. These include:
Lavender
Rosemary
Marigolds
Sage
Placing foxtail ferns closer to human activity or in highly visible areas may also reduce deer visits, as they prefer more secluded feeding spots.
