Companion Planting for Corn: Enhancing Your Harvest with the Right Plants
Good Companion Plants for Corn
Corn is a staple crop that has been cultivated by humans for centuries. It is a versatile plant that can be used for food, fuel, and animal feed. However, growing corn can be challenging, especially if you want to maximize your yield. One way to enhance your harvest is through companion planting. Companion planting involves growing two or more plants together to benefit each other. In this article, we will discuss some of the best companion plants for corn.
1. Beans
Beans are one of the most popular companion plants for corn. They are nitrogen-fixing plants, which means they convert atmospheric nitrogen into a form that is usable by plants. Corn, on the other hand, requires large amounts of nitrogen to grow. By planting beans alongside corn, you can improve soil fertility and increase your yield. Additionally, beans provide shade for the corn, which helps to conserve moisture and reduce weed growth.
How to Plant Beans with Corn
To plant beans with corn, you can either intercrop them or plant them in alternating rows. If you choose to intercrop, plant the beans after the corn has reached a height of 6 inches. Plant the beans between the rows of corn, spacing them about 6 inches apart. Alternatively, you can plant the beans in alternating rows with the corn, spacing them about 8 inches apart.
2. Squash
Squash is another good companion plant for corn. Like beans, squash provides shade for the corn, which helps to conserve moisture and reduce weed growth. Additionally, squash has shallow roots that do not compete with the corn for nutrients. Squash also helps to repel pests like cucumber beetles and squash bugs, which can damage corn plants.
