Corn Companion Plants Planting in your Garden


Sweet corn is pollinated by bees and butterflies. Other crops are planted alongside of sweet corn in order to attract these pollinators. The other plants help to create a habitat that attracts these creatures and in turn, helps to pollinate the sweet corn.


The cucumber is a vine that grows on the ground. It helps to shade the ground and keep the moisture in, which is beneficial for plants like corn. Corn also helps to attract beneficial insects like bees, which help to pollinate the cucumbers. Cucumbers are harvested at 50-70 days, depending on the variety. They can be eaten fresh or used in recipes. Corn and cucumber are good for each other and can be grown together in a garden.

Pole beans

Nitrogen is an important nutrient for plants and corn needs nitrogen to grow. One way to provide nitrogen for corn is to plant pole beans next to the corn. Pole beans are able to fix nitrogen in the soil while they climb up the stalks of the corn. This process helps improve the fertility of the soil and provides nitrogen for the corn. Additionally, planting beans and corn together can be beneficial because the beans act as a natural trellis for the corn, helping it grow taller and straighter.

Winter squashes

Winter squash is a must in any garden. Not only does it provide many benefits to the garden, but it is also one of the most versatile vegetables around. It can be used in so many dishes and is a great addition to any meal. Gardeners should make sure they give their winter squash plants a head start, as they need plenty of time to mature. They can be found in the orchard, along with apples. Corn and beans are companion plants and work well together in the garden.

Tomatoes are a popular garden vegetable because they are relatively easy to grow and come in a variety of colors and sizes. However, tomatoes can be susceptible to pests, including the hornworm. Hornworms are green caterpillars with a decorative pattern on their sides. They like to eat tomatoes as well as corn, so it is important to be aware of them if you are growing either of those crops. There are several ways to control hornworms, including trapping them, handpicking them, or suffocating them with oil. Another common name for the caterpillar that eats crops is the corn earworm


Tomato hornworms are attracted to eggplants because they both belong to the nightshade family. While they are not harmful to each other, it is recommended that you keep them separate in your garden.
