If rabbits have invaded your garden, you're most likely not a happy camper. Those cute and cuddly animals with their cotton-ball-like tails, wiggly noses and impressive ears, have sharp teeth and a healthy appetite, which can do significant damage to your lettuce crops. Most don't even survive a whole year and reproduce like they're running out of time. To save your crops, use one or more methods to keep these avid nibblers out of your garden.
Incorporate scare tactics to frighten rabbits away. Run a piece of an old water hose between the rows of lettuce. When "Peter Rabbit" and his friends come around, they might think the decoy is a snake and run off. Move the hose daily to make it seem like a real snake. Alternatively, use store-bought toy snakes.
Seal off openings under steps or nearby buildings, and remove debris, weeds and other unnecessary vegetation from your garden, because these can double as hiding places for rabbits.
Scatter a foul-smelling substance on the soil around the lettuce. Use powdered aloe, blood meal or black or red pepper. When rabbits smell the odor, they'll think twice about going near your crops. Reapply the repellent regularly, especially after rainfall. Apply it before nightfall, because this is when rabbits do the most damage.
Grow rabbit-deterring plants around your garden. Borden off your lettuce with globe thistle or catmint, which can all stop rabbits in their tracks. Alternatively, grow a border of clover around your garden, because rabbits love clover and might prefer to nibble on it more so than the lettuce.
Install a wire fence around your garden to keep rabbits out. Use a wire fence that's at least 2 feet tall and has openings that are no larger than 1 1/2 inch. Bury the fence at least 8 inches deep and bend the underground part of the fence 90 degrees outward to discourage rabbits from digging their way into your garden.
