Few people are not annoyed by having stray cats cruise their flower beds. A purring cat in your lap is one thing. Having one dig up your flowers is another. There are numerous remedies for keeping uninvited felines at a distance.
Flowers to Plant
Cats don’t like the smell of lavender, absinthe, lemon thyme, rue or geranium. Plant those among your flowers. Cats are alleged not to like the smell of marigolds, which are pretty flowers and good to have if they keep cats away.
Hot and Smelly Stuff
Mix five parts of flour with two parts of cayenne pepper and three parts dry mustard, and sprinkle the mixture among your flowers. Scattering black pepper or cayenne pepper among your flowers will keep cats away, but these peppers are expensive, and you have to reapply them after it rains.
Put a handful of habanera or other hot chili peppers and a few bulbs of garlic into a quart of water and blend well. Spray this on your flowers. Cats are also put off by tea leaves. Remove the tea leaves from used bags and sprinkle them around your flowers.

Lay concrete reinforcing wire across the entrances to the areas where you have flowers. Spray this with eucalyptus oil or anise oil. Cats are put off by the smell and don’t like picking their way across the openings in the wire.
Cats hate to get wet. If you can afford it, attach a motion sensor to a sprinkler. When the cat strolls invited into your flowers, it gets wet.
You can buy an ultrasound device that is motion-activated. It emits a sound that you can’t hear but that drives cats nuts.
