Did you ever think of your herbs as being garden sentries? Well, they can be.
What exactly is the definition of sentry? The dictionary says it's this: A guard, especially a soldier, posted at a given spot to prevent the passage of unauthorized persons.
Even though my herbs are not soldiers, I have been using them as guards and sentries, and the "person" they are guarding against are deer! When I created my Square Foot Garden, I planned my herb 4x4 square so that it would be on the side of my yard that the deer were most likely to pass by. My herb square contains rosemary, oregano, thyme, along with others, but these three are good deer deterrents. Deer have very sensitive noses, and they don't like to be near anything with a powerful scent.
At the entrance to my garden area, I placed a pot of herbs at each end. One contains lemon balm, because I like it, and the other container is mint. Deer hate mint.
The season is far from over, but so far I have not seen a deer print anywhere near my garden, and no rabbits have stopped by for a nibble The raccoons are not digging into my root vegetables, either! I have begun to harvest a few things, and, so far, have not had to sacrifice anything to my hungry woodland friends, thanks to my herbs, my garden sentry!
