Good companions for green beans

  • Sweet corn

    Traditional practice

    In a Three Sisters planting, pole beans can climb corn stalks.

    An Indigenous American growing system pairs corn, climbing beans and squash. Corn provides a living trellis; this describes a traditional system, not a guaranteed yield increase in every garden.

    Spacing: Plant corn first and add beans once corn is established so beans don't overwhelm young stalks.

    Pests: No pest-control benefit is claimed for this pairing.

  • Summer squash

    Traditional practice

    Beans and squash are the companion pair in the Three Sisters system.

    Both are grown around corn in the traditional system. Outside that layout, there is no sourced benefit specific to these two crops.

    Spacing: Preserve each crop's mature spacing.

    Pests: No pest-control benefit is claimed for this pairing.
