Outdoor cats can cause problems to a garden by digging up flower beds or urinating on the soil. Cat urine can hurt several types of plants and flowers, and it may also repel helpful insects and pollinators. There are several tips that gardeners have tried to keep cats out of a flower bed, but it's best to try the simplest strategies of keeping them out until the problem is corrected.
Cover any bare soil with pinecones, gravel or slate chippings, which will help to discourage any cats from digging in the flower bed.
Scatter orange peels around the garden. Cats detest the smell of citrus and using orange peels is a beneficial way of keeping them away from the flower bed. You can also spray the area with a citrus scent that is safe to spray on flowers.
Spread crushed eggshells and coffee grounds around your flower bed. The sharp edges of the eggshells will deter the cats from treading in the garden.
Purchase a chemical cat deterrent if the problem persists. The active ingredient in these products is typically methylnonylketone and it should not be sprayed around any growing fruits or vegetables.
Install garden netting directly over the soil of the flower bed. The netting should be at least 1 to 2 inches above the soil. Place pine cones and mulch on the netting and around the flower bed.
