The Benefits of Companion Planting with Corn

Corn is a heavy feeder that requires a lot of nutrients from the soil. Companion planting can help reduce soil erosion, attract beneficial insects, and fix nitrogen in the soil. By planting certain crops alongside your corn, you can also improve its taste, texture, and overall health.

The Best Companion Crops for Corn

Here are some of the best companion crops for corn:

Beans

Beans are one of the most popular companion crops for corn. They are legumes that fix nitrogen in the soil, which corn needs to grow strong and healthy. Additionally, beans have shallow roots that spread out near the surface, helping to suppress weed growth and prevent soil erosion. It's recommended to plant bush beans instead of pole beans as they won't compete for sunlight and nutrients.

Squash

Squash is another great companion crop for corn. It grows low to the ground, providing shade and moisture retention for the corn roots. Squash also has large leaves that can help smother weeds and retain moisture in the soil. However, it's important to note that squash should only be planted when the corn has reached a height of 12 inches or more to avoid overcrowding.

Peas

Peas are another legume that can fix nitrogen in the soil. They also have a shallow root system, which makes them an ideal companion crop for corn. Peas can be planted alongside corn as soon as the soil can be worked in the spring. However, it's recommended to plant them in a different section of your garden each year to prevent disease buildup.

Cucumbers

Cucumbers are a fast-growing crop that can help shade the soil and conserve moisture. They also have shallow roots that won't compete with corn for nutrients. Cucumbers can be grown on trellises, which can save space in your garden and allow for easy harvesting.

Pumpkins

Pumpkins are a great companion crop for corn as they can help suppress weeds and provide shade for the soil. They grow low to the ground and have large leaves that can help retain moisture in the soil. Additionally, pumpkins can be harvested in the fall, which allows you to extend your growing season.

Other Companion Plants for Corn

Borage

Borage is a flowering herb that attracts beneficial insects like bees and butterflies. It also has deep roots that can help break up compacted soil and improve drainage.

Nasturtiums

Nasturtiums are a colorful flower that can help repel pests like aphids and squash bugs. They also attract beneficial insects like bees and ladybugs.

Marigolds

Marigolds are a well-known companion plant that can help repel pests like nematodes and whiteflies. They also add color to your garden and attract beneficial insects.

Tips for Companion Planting with Corn

Plant in a Block

When planting corn and its companion crops, it's best to plant them in a block rather than in rows. This will allow for better pollination and make it easier for the plants to share nutrients.

Rotate Crops

It's important to rotate your crops each year to prevent disease buildup and nutrient depletion. Plant corn in a different section of your garden each year and avoid planting it in the same spot for at least three years.

Provide Adequate Watering

Corn and its companion crops require adequate watering to grow strong and healthy. Be sure to water them deeply and regularly, especially during hot and dry weather.
