Hostas, with their lush, broad leaves and tender texture, are a favorite food source for rabbits. These plants are highly palatable, often resulting in ragged edges and decimated foliage overnight. Protecting hostas requires a strategy that combines physical barriers, taste and scent manipulation, and adjustments to the garden environment.
Physical Barriers and Exclusion Methods
The most reliable way to protect hostas involves physically preventing rabbits from accessing the plants. Permanent perimeter fencing is highly effective, but it must be constructed correctly to account for a rabbit’s ability to jump and burrow. The fence should stand at least two feet high. Using a small-mesh wire, such as chicken wire or hardware cloth, ensures that smaller rabbits cannot squeeze through the openings.
Because rabbits are proficient diggers, the barrier must also extend below the soil line. Burying the bottom of the wire four to six inches deep discourages burrowing attempts. Alternatively, bend the bottom six inches of the wire outward, creating an “L” shape on the ground that prevents rabbits from digging right up against the barrier. For individual plants, temporary cages made from hardware cloth can be placed directly over the plant until the foliage is larger.
Taste and Scent Deterrents
When physical exclusion is impractical, use repellents to make the hostas unappetizing. Commercial sprays frequently use active ingredients like putrescent egg solids, which mimic the scent of decaying matter, signaling danger. Other formulations rely on strong, distasteful compounds such as capsaicin, garlic oil, or predator urine to establish an olfactory or taste barrier. These topical repellents must be reapplied frequently, especially after heavy rainfall, since their effectiveness diminishes when washed off the leaves.
Gardeners may also use homemade deterrents that exploit the rabbit’s sensitive nose and palate. Sprinkling strong-smelling items like dried blood meal, garlic powder, or red pepper flakes directly around the base of the hostas creates an unappealing zone. Rabbits can become accustomed to the smell or taste over time. For continued success, rotate between different types of repellents—switching from an egg-based spray to a capsaicin-based one, for example—to prevent habituation.
Environmental and Cultural Adjustments
Long-term protection involves making the garden area less welcoming by modifying their habitat. Rabbits prefer to forage near areas that provide immediate cover for escape, so reducing hiding spots is an effective strategy. Removing dense brush piles, tall weeds, and debris, or blocking access underneath low decks and porches, limits the places where rabbits can rest and breed.
Companion planting involves strategically placing rabbit-resistant species near vulnerable hostas. Plants with strong aromas can mask the appealing scent of the hosta foliage, making it harder for rabbits to locate their preferred meal. These fragrant plants serve as a natural buffer zone, encouraging rabbits to browse elsewhere.

- Onions
- Rosemary
Devices that use sudden, startling action, like motion-activated sprinklers, can temporarily deter persistent visitors. Visual deterrents, such as owl decoys or rubber snakes, are often ineffective because rabbits quickly realize these stationary objects pose no real threat.
