African Daisies, known botanically as Osteospermum, are popular garden plants with vibrant, daisy-like blooms. They add visual appeal to garden beds, borders, and containers. Deer can pose a significant challenge for gardeners, raising concerns about plant damage. This article addresses whether African Daisies are susceptible to deer browsing.
Do Deer Eat African Daisies?
African Daisies are considered deer-resistant, making them a suitable choice for gardens in areas with deer activity. Rutgers University classifies them as “Rarely Damaged,” indicating they are among the most deer-resistant annuals.
While not a preferred food source, no plant is entirely deer-proof. Deer may browse African Daisies if other food sources are scarce, especially during times of drought or harsh winters when their usual forage is limited. Young, tender plants might also be more vulnerable.
Understanding Deer Browsing Habits
Deer browsing behavior is influenced by factors beyond simple hunger. Deer avoid plants with strong scents, and African Daisies often have a distinct aroma. Plant texture also plays a role; deer dislike fuzzy, hairy, or tough foliage. African Daisies have papery flower bracts and tough stems and leaves, which can deter deer.
Environmental conditions also impact what deer choose to eat. During drought or high deer populations, deer may be less selective and consume plants they would normally ignore. The availability of preferred food sources in the surrounding landscape influences their diet; if usual forage is limited, deer might venture into gardens and browse on less palatable plants.
Strategies for Protecting Your Plants
To protect African Daisies from deer, gardeners can implement several strategies. Physical barriers, such as fencing, are effective in preventing deer access. A deer fence should be at least 6 to 8 feet tall, as deer can jump high, and anchored to the ground to prevent crawling underneath.
Repellents offer another layer of defense, working through scent or taste to deter deer. Commercial sprays often contain ingredients like putrescent egg solids, garlic, or hot pepper, which create unpleasant odors or tastes. These repellents require regular reapplication, especially after rain, as their effectiveness can diminish over time. Homemade remedies, like strong-smelling soaps, can also be tried.
Companion planting involves placing African Daisies near strongly scented, deer-resistant plants like herbs (e.g., rosemary, sage, thyme) or other pungent flowers (e.g., marigolds). These plants can help mask the scent of more appealing vegetation, making the area less attractive to deer. Planting African Daisies in areas with frequent human activity, such as near a patio or deck, can deter deer, as they avoid high-traffic zones. Regular monitoring for signs of browsing allows for early intervention and adjustment of protection methods.
