How to use companion plants

Companion planting has been round for centuries. In the days when chemical pesticides did not exist, farmers had to find more natural ways to keep harmful bugs from infesting their crops. Over time they began to realize that certain plants did better when planted with each other, sharing in their fight against harmful bugs, while others fared badly if placed too close together. Modern gardeners have continued to use and perfect this technique, called companion planting.

We come from the earth, we return to the earth, and in between we garden. "When the world wearies and society wearies and society ceases to satisfy there is always the garden." -M. Aumonier
