It is possible to grow rhubarb in a container. Because rhubarb has a large root system, you’ll need a deep pot. Find a sturdy container that is at least 20” deep and wide. Make sure it has drainage holes. While rhubarb needs a period of cold temperatures, extreme cold can harm it. You might wrap the container in an insulated material or move it to a garage during the coldest part of winter.
