Companion Planting: Nature's Perfect Partners

“A good companion shortens the longest road.” –Turkish Proverb Quote

“It's easier to find a traveling companion than to get rid of one” –Art Buchwald

Companion planting represents organic gardening’s basic concept of learning from nature. The idea behind companion planting is that there are certain plants, when grown together, which have a mutually beneficial relationship unique to that combination. Companion planting has been practiced for centuries: you may be familiar with the traditional Native American combination of the “Three Sisters,” which combines corn, beans and squash. While many combinations of plants have been shared between gardeners for generations, science has also proven the many benefits.

The Three Sisters

  • The Myth - The story behind the “Three Sisters” begins as a creation myth from the Iroquois Indians. According to the myth, the Sky Woman fell from the sky after peering through a hole in it. She was pregnant when she fell, and when she landed on earth, she gave birth to a daughter. The daughter grew up and also became pregnant with twin boys, but she died in childbirth. Sky Woman buried her, and from her grave came three plants: corn, beans, and squash. From these plants, there was enough food for the twin boys, and later, all of humanity.
  • The Science - Studies have proven the symbiotic relationship of corn, beans, and squash. Corn provides a structure for the beans to climb. In return, the beans replenish the soil with nutrients, particularly nitrogen, which corn uses heavily. All plants need nitrogen as food and beans work with the rhizobium bacteria to convert nitrogen in the air into a useable source in the soil. Finally, the squash leaves serve as living mulch for the other two plants. Because they grow close to the ground, they block out sunlight which reduces seed germination from weeds.
