A container for growing plants includes a side wall defining an open top, an open bottom, and a cavity for receiving a plant and a plant growth medium. The side wall may be composed of a biodegradable material and may be flexible, yet rigid enough to be self-supporting. The side wall may also be smooth on its outer surface for receiving selected printed indicia, such as product information and growth instructions. In certain embodiments, the side wall may be laminated, contain openings, or have a handle disposed thereon. The container is used by placing a plant and a plant growth medium in the container, then exposing the resulting potted plant to selected conditions of temperature, moisture, and light. The potted plant may also be placed in soil or in a larger container without the need to remove the biodegradable container.
