Rabbits are common garden pests that can quickly destroy young plants, clipping off shoots and consuming tender leaves with their sharp incisors. Protecting a garden from these persistent herbivores requires a multi-faceted approach, combining direct applications of deterrents, the installation of physical barriers, and smart planting choices. The most effective strategies focus on exploiting the rabbit’s acute senses and natural behaviors, rather than relying on a single method. Understanding the difference between temporary applied repellents and permanent physical deterrents is the first step toward effective control.
Applied Taste and Scent Repellents
Applied repellents work by targeting a rabbit’s sensitive nose and palate, making the treated plants unappealing. These products generally operate through two mechanisms: taste aversion and scent disruption. For taste aversion, capsaicin, the compound that gives hot peppers their heat, is a highly effective ingredient in many commercial and homemade sprays. Capsaicin binds to pain receptors in the rabbit’s mouth and nose, creating a burning sensation that teaches the animal to avoid the treated foliage.
Scent disruption products rely on odors that signal danger or decay, exploiting the rabbit’s instinct for survival. A widely used commercial active ingredient is putrescent egg solids, which releases sulfurous compounds as it decomposes. This putrid smell mimics the odor of a predator’s carcass or territory, triggering a strong fear response. Other ingredients like dried blood, garlic oil, and thiram also create offensive odors or tastes.
These solutions require diligent reapplication because new plant growth is unprotected, and rain or overhead watering can quickly wash away the active ingredients. To maintain effectiveness, gardeners should reapply liquid sprays every few weeks or immediately after a heavy rainfall. Gardeners should also rotate different types of repellents, switching between taste-based and scent-based products, to prevent rabbits from becoming accustomed to a single deterrent.
Building Physical Barriers
Physical barriers offer the most reliable, long-term solution from rabbits. The fence design must account for the animal’s ability to both jump and burrow. Use galvanized wire mesh or poultry netting with a small opening size, ideally 1 inch or less, to prevent young rabbits from squeezing through.
The fence must stand at least 24 to 36 inches above the ground, as rabbits can occasionally jump over lower barriers when startled or motivated. The underground portion prevents burrowing, requiring the mesh to be buried at least 6 inches deep to deter rabbits from digging underneath the barrier.
The buried portion should be bent outward in an “L” shape, extending 6 inches away from the garden. This outward-facing flange acts as a deterrent plate that the rabbit encounters when it attempts to dig at the fence line. For protecting individual, high-value plants or new seedlings, temporary barriers like wire cages or cloches offer localized protection until the plants are established.
Gardening with Rabbit-Resistant Plants and Habitat Control
Rabbits naturally avoid plants that have strong, pungent aromas, such as many herbs, or foliage with a bitter, toxic taste. Plants with physical defenses like fuzzy, hairy, or coarse-textured leaves are also less appealing to them.
Common examples of plants that possess these natural defenses include aromatic herbs like lavender, mint, and oregano, as well as flowering bulbs such as daffodils and ornamental alliums. While no plant is entirely immune to a hungry rabbit, incorporating these species can significantly reduce grazing pressure in a garden.
Reducing the attractiveness of the environment itself is another passive control method. Rabbits seek shelter close to their food source, so removing potential daytime hiding spots near the garden perimeter makes the area less hospitable. This includes clearing thick brush piles, managing tall weeds, and blocking access to sheltered areas beneath low decks or sheds. By limiting comfortable cover, the gardener encourages rabbits to forage elsewhere.
