Will coffee grounds or moth balls keep cats out? Do you mix them in or lay a border? Any better suggestions?
I know I used fur from my cat when we ha something digging in our garden but to get rid of cats I don't know I'd guess planting hot peppers all over maby?
I've never had luck with mothballs...
Over the years I have read many different deterrents like aromatic plants such as geraniums or rue.
Fill shallow plates with white vinegar. Place the plates around the perimeter
fresh ground up orange, grapefruit or lemon peels throughout the areas. Cats do not like the smell of citrus peels
Mesh or chicken wire prevents them from digging.
You could also plant catnip in another area of the yard to attract cats to that section only.
Cats are really harmful for plants. You should place an strong border around every plant. so that cat cannot reach to your garden.
I'm getting a motion detector sprinkle. Great for keeping the deer and groundhog away too!
