Monkey grass, encompassing popular varieties like Liriope and Ophiopogon, is a popular, low-maintenance plant often used as groundcover or borders. Its widespread use frequently leads to a common question in deer-prone areas: do deer eat monkey grass?
Understanding Deer and Monkey Grass
Monkey grass is generally considered deer-resistant, meaning deer typically avoid browsing on it. This resistance stems from its tough, fibrous leaves, which are unpalatable and unpleasant to deer. The plant also lacks a strong scent that would attract them. While not a preferred food, no plant is entirely “deer-proof.” Deer are opportunistic feeders, and their behavior varies based on environmental factors and individual preferences.
Factors Influencing Deer Foraging Habits
Despite its general resistance, deer may browse on monkey grass under certain circumstances. Extreme food scarcity, such as during droughts or harsh winters, can compel deer to eat plants they normally avoid. High deer population density also increases browsing pressure on less palatable plants, as competition for food intensifies. Young, tender growth of monkey grass might also be more appealing than mature foliage. Individual deer preferences can also play a role.
Deterring Deer from Your Garden
If deer browsing becomes an issue, several strategies can protect monkey grass and other garden plants. Physical barriers like fencing are effective, though deer fences need to be at least 7 to 8 feet tall to prevent jumping. Shorter fences can work if combined with other deterrents, like cobblestones or dense shrubbery, which make deer hesitant to jump without a clear landing.
Various deer repellents are available, working by taste or smell, often containing ingredients like putrescent egg solids, garlic, or predator urine. These repellents require regular reapplication, especially after rain. Rotating different types can prevent deer from becoming accustomed to one deterrent.
Companion planting with strongly scented plants like lavender, rosemary, mint, or marigolds can deter deer by masking the scent of more appealing plants. Motion-activated sprinklers or reflective objects can also discourage them.
Other Deer-Resistant Groundcovers
For alternatives, several other groundcovers deter deer. Ajuga (bugleweed) is deer-resistant due to its bitter taste. Sedum (stonecrop) is generally avoided because of its thick, fleshy leaves and bitter taste. Creeping phlox is unappealing due to its pungent scent. Lavender, with its strong aroma and bitter taste, and Lamb’s ear, with its fuzzy leaves, are also plants deer tend to avoid.
