For gardens near woodland areas or known deer habitats, it’s beneficial to plant these companions along the borders to create a natural barrier. Mix these repellent plants into the same containers if you’re growing tomatoes in pots.
Used coffee grounds serve as an eco-friendly deer repellent. The strong scent of the grounds will act as an unpleasant deterrent for deer, and they’ll stay away from areas where it is present.
The fishing line is nearly invisible, making it an effective barrier against deer. It is also better at detecting predators than thin barriers. When strung around your garden, it forms an invisible fence.
Use dogs as natural deer deterrents. Dogs actively chase away deer. Regular patrols by your dogs can instill fear in deer and alert you to their presence through barking.
The scent of human hair can act as a deer deterrent when placed around the perimeter of your garden. Ask your barber or hairdresser for hair clippings; you might have to sweep them up, but they’re usually free.
