Companion Planting

Part of "Growing Food"

 

Plants exert influence over each other in many ways. For example, bush beans do well when planted with cucumbers. Celery grows wells when planted near tomatoes, leeks. Radishes grown with lettuce in summer are said to be very juicy. Onions help cabbages by warding off pests such as the the common cabbageworms.  

Other planting pairs are negative, as in the case of a root exudant that inhibits the growth or flavor of another plants. Onions and peas, for example should not be planted near each other.

 

Companion plants interact with each other by releasing chemical compounds from their roots, or scents from their leaves and flowers, that can either encourage or discourage growth of another nearby plant. Some companion plants attract beneficial insects and microorganisms that can help nearby plants.

While companion planting is being researched, much of the knowledge is based on farmer's observations through the decades.
