what are companion plants for beans
These companion plants can add elements to the soil, keep pests away, help with pollination or act as bait to draw pests to it instead of your vegetable plants. To companion plant bush and pole beans, you'll want to plan your garden in advance to allow room for all of your plants, not just the beans. Decide if you want to interplant your beans with other vegetables, flowers, herbs or a mixture of all three.
The Three Sisters. The traditional Native American planting of corn, beans and squash makes an ideal companion combination. Corn is planted first, and when it is tall enough to provide support, pole beans are planted next to each corn stalk. The beans provide nitrogen to the corn, and the corn provides a stalk for the beans to climb.
