Companion planting is a form of natural pest control. Basically it means to grow plants that repel certain pests along with the regular plants in your garden. If you add plants to your garden that have odors or tastes that are offensive to pests, the insects will move on to other feeding grounds. Finding the right plants is something of a matter of trial and error depending on your geographical location, but below are some suggestions.
