Companion Planting

I am still interested in agricultural trends/innovations by way of what I read in the book on the Grameen Bank.

One I intend to try this year is known as the “three sisters” method- planting three specific vegetables together to improve efficiency:

  1. build flat-topped mounds of soil for each “cluster”
  2. plant several corn seeds close together, in the very center
  3. when the corn is 6 inches tall, plant beans and squash around the corn, alternating between beans and squash
  4. The plants grow together in a single group:
    • The corn provides a structure for the beans to climb, eliminating the need for poles
    • The beans provide the nitrogen to the soil that the other plants remove
    • The squash spreads along the ground, monopolizing the sunlight to prevent weeds
    • The squash also acts as a “living mulch,” creating a microclimate to retain moisture in the soil

The Iroquois used this technique… I am looking for other techniques to cut down on labor and improve the amount of nutrition for a given size of land.

But wait there’s more- closely connected to this idea is “biointensive farming”- using closely-planted crops to create microclimates, as well as reduce erosion.

  • The Growing “The Three Sisters”:
    Corn, Beans, and Squash
    article has some good drawings to quickly demonstrate what this looks like. From Garden Gate magazine.
  • More on “Companion Planting“- extending beyond the Three Sisters. For example growing chives near carrots to improve the carrots’ flavor!
  • Pinning down the politics of Minifarms is tricky but in the end moot. They have articles on Raised Bed Agriculture (“RBA”) and biointensive farming. They talk about “growing soil”- choosing crops to improve the quality of the soil with every crop.
  • The Center for Agroecology & Sustainable Food Systems is a research, education, and public service program at the University of California, Santa Cruz, dedicated to increasing ecological sustainability and social justice in the food and agriculture system.” Here is their downloadable resources for teachers. I seriously wish I had a class like this at Berkeley, instead of “American Environmental Cultural History” which was largely mewling bunk.

  1. What if…you don’t wanna plant corns, beans, or squash?

    Corn is cool — but bean vines get kind of messy…and squash? Squash vines grow EVERYWHERE! And of course, they aren’t very “pretty”

    😉

    But — thanks for the link to companion planting — I see there are other combos. I may have to clear out a part of my yard for this idea. Excellent.

  2. Just finished “Banker to the Poor.” Great!
    Check out Wes Jackson, founder of the Land Institute. He does some great stuff on sustainable agriculture.
