How Do I Keep Cats Out of the Garden?

How do I keep cats out of the garden? Question from Richard of Winston Salem, North Carolina.

Answer: Even if you love cats, they can be real pests in the garden, even though they keep a wide variety of other garden pests at bay. Their love of soft mulch and soil for defecation encourages them to treat nice garden ground as makeshift cat boxes. Bird lovers also frown at cats hovering around their yards and feeders.

There are several methods for deterring cats from the garden. You will have the best luck if you target the areas where cats are the biggest problem. Here are my recommendations.

Repellent Plantings

First, you can rely on natural or store-bought repellents.  Cats dislike strong citrus and menthol smells. So during the summer months, you can plant herbs that they dislike. These include the attractive cat repellent plant (Plectranthus caninus), lemon verbena (Aloysia citriodora), lavender (Lavandula spp.), rosemary (Rosmarinus officinalis), rue (Ruta graveolens), and sage (Salvia officinalis). Oniony smells are also not cat favorites, so chives (Allium schoenoprasum) or summer ornamental onion (Allium ‘Summer Beauty’) are other planting options. (Click here to learn more about planting lemon-scented herbs or other garden herbs.)

Many commercial repellents also exist. I recommend reading customer reviews to find the best one to repel cats.

Catproof Plantings

Cats like open ground, so don’t leave large spaces between plantings. Dense groundcovers and prickly plantings of all kinds will do a lot to keep cats away. Roses, hollies, mahonia, and low-growing junipers and pines are all good prickly plant choices. Sweet box (Sarcococca hookeriana var. humilis), spotted deadnettle (Lamium maculatum), thyme (Thymus spp.), and bugleweed (Ajuga reptans) are all good groundcovers to ward off cat digging.

Rethinking Mulch

Well-placed rocks or stone soil covers will also keep cats from digging in favorite places. You may also consider placing a mulch of prickly pinecones in strategic places. For vegetable gardens, I recommend putting down a layer of mulch cloth or thick wetted newspaper and covering that with an additional layer of hay or pine straw. Not only will this keep weeds down, but it will discourage cats from digging.

Automated Scarecrows

There are lots of motion sensor “scarecrows” to keep cats away from garden areas. These include those that spray water or emit ultrasound or other sounds to frighten away cats. Once again, read reviews before making an investment. Customer satisfaction is always the best means for determining whether a costly product is worth your money.


Cats can easily jump fences, but a 4-foot wire fence around a vegetable garden plot may be enough to ward them off.  This will also keep rabbits away.

Cats Lures

It may sound counterproductive, but some people have had success planting catnip or other cat-attractant plants away from precious garden areas. A planting on your yard’s periphery may prove helpful.

I hope that these tips are useful!

Best Low-Light House Plants for Cats

“What are the best low-light house plants that are cat safe?” Question from Margaret of Houston, Texas

Each of these eight beautiful house plants grow well in shade or filtered sunlight, and according to the ASPCA, all are non-toxic to cats.

Cast Iron Plant

Non-Toxic House Plants for Cats

Cast Iron Plant (Aspidistra elatior, full to part shade, 1-3 feet): This bold-leaved house plant needs average water and fertile soil. Some varieties have gold or variegated leaves.

Rex Begonia (Begonia rex-cultorum, part shade, 1-2 feet): Grown for their fantastic leaves and flowers, these are some of the prettiest houseplants that are cat safe.

Parlor Palm (Chamaedorea elegans, full to part shade, 2-6 feet): The classic parlor palm, with its deep green palm leaves, looks great indoors and is safe for all pets.

Rex Begonia

Spider Plant (Chlorophytum comosum, full to part shade, 1-2 feet (cascading)): The classic spider plant is safely chewed upon by cats like cat grass and is very easy to grow.

False Aralia (Schefflera elegantissima, part shade, 5-10 feet (indoors)): False aralia has beautiful foliage and is very easy to grow in partially shaded areas.

Boston Fern (Nephrolepis exaltata, part shade, 2-3 feet): Common Boston ferns are lovely, safe, and always pretty in low-light spots in the home. Just be sure to water them regularly and remove old, browning fronds.

Parlor Palm

Emerald Ripple Peperomia (Peperomia caperata, part shade, 6-10 inches): The corrugated leaves of this compact house plant always look pretty and won’t pose a threat to cats.

Silverleaf Peperomia (Peperomia griseoargentea, part shade, 6-18 inches): This peperomia has silvery, textural leaves that glow in partial shade locations in the home.

House Plant Care

All of these house plants will thrive in Black Gold All-Purpose Potting Mix, which is specially formulated for indoor growing. Choose a planting pot that is just larger than the root ball of your house plant, and leave at least 2-3 inches of space at the top for watering.

Water plants regularly. Feel the soil down to your middle knuckle, and if it’s dry, it’s time to water. Less water is generally needed during the cold winter months. House plants also grow better if fed with a quality fertilizer formulated for house plants.

Be sure to place house plants away from heating vents, as this causes their leaves and soil to dry more quickly. It is also wise to clean the leaves of house plants to remove dust that can inhibit growth. This is especially necessary for larger-leaved specimens that readily collect dust.
