The relationship between plants and insects is known as “companion planting”. Long before the use of chemical fertilizers and pesticides, it was known that certain plants grow and/or taste better when planted next to each other. One type of plant may help another by providing shelter From wind, sun, or frost. Plants may help each other by improving the soil with minerals and nutrients. They can attract birds and other natural predators that will deal with harmful insects on plants. Plants can also repel specific insects. Today companion planting is by far the safest, natural way to garden organically.
