Companion Planting

Oct 4, 2011

Companion planting, or intercropping, can create improved biodiversity in agroecosystems. The concepts of companion planting can be used in home gardens or in commercial agriculture.

Beneficial plant associations can provide many positive interactions in the field or garden. They include:

  • Trap cropping
  • Symbiotic nitrogen fixation
  • Biochemical pest suppression
  • Physical spatial interactions
  • Nurse cropping
  • Beneficial habitats
  • Security through diversity
