It is recommended to choose a container with a minimum depth of 12 inches and a capacity of at least 5 gallons to accommodate the corn’s root structure.

However, if you have limited space, you can still grow corn in smaller containers by selecting dwarf or compact corn varieties that require less space. These varieties are specifically bred to grow well in containers and can reach heights of about 4-5 feet.

Container Options

There is a wide range of container options available for growing corn, including plastic pots, wooden boxes, fabric grow bags, and even repurposed items such as buckets or barrels. Each container type has its own advantages and considerations.

Expert Tip: When using containers made of materials that absorb heat, such as metal or dark-colored plastic, consider placing them in partial shade to prevent the soil from overheating, which can stress the corn plants.

Plastic pots are lightweight, durable, and come in various sizes. They provide good insulation, retaining moisture and regulating soil temperature. Wooden boxes are a popular choice for their aesthetic appeal and excellent drainage. Fabric grow bags are breathable and promote better air circulation around the roots. Repurposed containers can be cost-effective and environmentally friendly options.


Ensuring proper drainage is vital for the success of container-grown corn. Corn plants require well-draining soil to prevent waterlogging, which can lead to root rot and other issues. To improve drainage, consider adding a layer of gravel or broken pottery pieces at the bottom of the container.
