Good companions for corn

  • 🫘 Bean

    Beans climb the stalks and feed the corn with nitrogen.

  • 🥒 Zucchini

    Squash leaves shade the soil, keeping moisture in and weeds out.

    Can use corn stalks for support.

  • 🫛 Pea

What not to plant with corn

    Corn earworm and tomato fruitworm are the same pest.
