Freesias, with their vibrant colors and sweet fragrance, are popular garden flowers. A common concern for gardeners is deer browsing. Understanding how deer interact with freesias is important.
Freesias and Deer Preference
Freesias are often categorized as deer-resistant plants, but not entirely deer-proof. Their strong, sweet fragrance can be off-putting to deer. This intense aroma acts as a natural deterrent, leading deer to typically avoid them when other food sources are abundant.
Beyond their scent, freesias belong to the Iridaceae family, which contains compounds that can deter herbivores. Despite these characteristics, a hungry deer, especially in areas with high populations or during food scarcity, may still sample or browse freesias. While some anecdotal evidence suggests deer simply walk past them, other reports indicate deer find their tender foliage and fragrant flowers appealing.
Understanding Deer Feeding Habits
Deer are adaptable herbivores with diverse diets. Their feeding choices are primarily influenced by palatability, nutritional content, and seasonal availability. They prefer tender, easily digestible vegetation that offers high protein.
Deer generally avoid plants with strong, pungent scents, bitter tastes, or those containing toxic compounds. Physical characteristics can also deter them; plants with fuzzy leaves, thorns, or a fibrous texture are often less appealing. However, while deer consume a wide variety of plants, including grasses, forbs, and woody browse, they will resort to less preferred options when their primary food sources become scarce due to environmental conditions or high population density.
Strategies for Deer Protection
Protecting freesias from deer often involves a multi-faceted approach, as no single method guarantees complete immunity. Physical barriers are highly effective; installing an eight-foot-tall fence around the garden, buried at least a foot deep, can prevent deer from jumping over or digging underneath. Netting can also be used to cover smaller plantings.
Deer repellents provide another layer of defense. These can include commercial sprays with unpleasant tastes or smells, or homemade solutions like Irish Spring soap, garlic, peppermint, or predator urine. Repellents typically need regular reapplication, especially after rain, to maintain their effectiveness.
Companion planting with other deer-resistant varieties can also help. Placing freesias near plants that deer consistently avoid, such as daffodils, alliums, hyacinths, marigolds, lavender, or sage, can deter browsing. Strategic plant placement, keeping freesias away from known deer pathways, further reduces the likelihood of damage. Combining these methods enhances protection, creating an environment less appealing to deer and allowing freesias to flourish.
