While cats go wild for some plants, such as catnip and catmint, they'll stay away from others if they're planted in your garden. If you find that you are constantly removing cat waste from your garden or that your cat or stray cats are digging in the garden and harming your plants, plant a few cat-repelling plants to keep them away!
Rue is a perennial shrub with blue flowers and silver-green leaves. While the plant will look lovely in your garden, cats find its scent offensive and will stay away. The plant is easy to care for and will do well even in poor soil conditions. Double the effect of rue by scattering its leaves over other areas of your garden to keep the cats away.
Cats also dislike lemon thyme, a variety of thyme with a lemon-y scent and taste. Like regular thyme, lemon thyme needs full sun to do well in your garden. Plant it near other herbs to protect them from an overly curious feline. As an added benefit, you can use lemon thyme in cooking!
Although most people find the scent and appearance of lavender to be refreshing, it's another plant that cats will steer clear of. Lavender does well in a container or in the ground. It needs full sun and well-draining soil to thrive. If you plant lavender in a container, make sure the container isn't too large. A too-big container won't dry out fast enough.
The scaredy cat plant was bred by a German gardener to repel cats from gardens. Of all the plants that cats dislike, not surprisingly the scaredy cat is the most repulsive to them. Humans find its appearance and scent appealing, though. It has blue flowers and smells of peppermint schnapps. You may find the scaredy cat plant at your local garden center, but most likely, you'll have to order it online or from a catalog.
