Companion planting is a farming technique that involves planting different crops together to benefit each other. Corn, being one of the most widely grown crops in the world, can benefit a lot from companion planting. In this guide, we’ll take a closer look at companion planting with corn, including the benefits, tips, and best plant companions.
The Benefits of Companion Planting with Corn
Companion planting with corn offers a lot of benefits, including:
- Improved soil health: Corn is a heavy feeder and can deplete the soil of nutrients. Planting legumes like beans or peas alongside corn can help fix nitrogen back into the soil.
- Natural pest control: Some plants, like marigolds or garlic, can repel pests that may damage corn crops.
- Better yields: Companion planting can help improve the overall health and yield of corn crops.
- Biodiversity: Planting a mix of crops can help promote biodiversity and create a more sustainable farming system.
Tips for Companion Planting with Corn
When it comes to companion planting with corn, there are a few things to keep in mind:
- Plant taller crops like sunflowers or pole beans on the north side of the corn to avoid shading.
- Avoid planting plants that are susceptible to the same pests as corn, like tomatoes or peppers.
- Plant companion plants after the corn has reached a height of at least 6 inches.
- Rotate your crops each year to avoid depleting the soil of specific nutrients.
Best Plant Companions for Corn
While there are many plants that can be planted alongside corn, some of the best plant companions include:
Beans are a great companion plant for corn as they help fix nitrogen back into the soil. You can plant bush beans or pole beans alongside corn.
Squash plants can help repel pests that may damage corn crops. They also have shallow roots that won’t compete with corn for nutrients.
Marigolds are known for their pest-repelling properties and can help keep pests like nematodes and beetles away from corn crops. Plant them around the perimeter of your corn patch.
Pole beans can climb up the corn stalks, making them a great choice for companion planting. They also help fix nitrogen back into the soil.
