Nasturtiums are common garden annuals, recognized by their bright, warm-colored flowers and distinctive, circular leaves with a peppery taste. Rabbits frequently consume this plant, and nasturtiums are generally considered safe for them to eat. Wild and domestic rabbits alike readily consume the leaves, flowers, and stems. This article explores why rabbits are attracted to nasturtiums, the health considerations, and methods for preventing their consumption in your garden.
Nasturtiums as a Rabbit Food Source
Rabbits are opportunistic herbivores, attracted to soft and succulent plants. Nasturtiums are highly palatable due to their tender texture and high moisture content, making them a desirable food source. The entire plant, including the leaves and flowers, is often consumed down to the stem base. The peppery flavor, which comes from mustard oils, does not deter a hungry rabbit. Wild rabbits view the plant as an easy-to-access snack when other forage is scarce.
Safety and Nutritional Considerations
Safety for Domestic Rabbits
Nasturtiums (Tropaeolum majus) are non-toxic and safe for rabbits to consume. They are nutritious, containing Vitamin C and micronutrients like iron, potassium, and calcium. For pet owners, nasturtiums should only be given as an occasional treat, never forming a significant portion of the diet.
Digestive Concerns
The primary concern with overfeeding is the plant’s high water content and relatively low fiber. An excess of watery greens can cause digestive upset, such as diarrhea, in domestic rabbits. Consuming too much low-fiber plant material displaces the hay and grass necessary for their diet, potentially contributing to serious conditions like gastrointestinal stasis. Wild rabbits rarely consume enough nasturtiums to cause serious harm due to their varied grazing habits. Pet owners should introduce nasturtiums slowly and sparingly as a supplement.
Protecting Nasturtiums from Rabbit Damage
Physical Barriers
Physical barriers are the most effective method for protecting nasturtiums from rabbits. A fence constructed from chicken wire or hardware cloth with a mesh size of one inch or smaller is highly recommended. The barrier should be at least two feet high and secured to the ground, as rabbits can jump surprisingly well. To prevent digging, the fencing material should be buried at least six inches deep. Alternatively, individual plants or small patches can be protected using cloches or row covers until they are established.
Sensory Deterrents
Sensory deterrents, which aim to make the plants unappealing, are often less reliable than fencing. These may include taste repellents containing ingredients like cayenne pepper or garlic, sprayed directly onto the foliage. The effectiveness of such sprays is variable and requires frequent reapplication, especially after rain or watering.
