Can rhubarb be grown in a bucket ?
at a push yes it spreads very quickly though so i dont know how successful or for how long if i was to grow in a bucket, i would make sure it was pretty big and i would put another bucket over the top, to keep it in the dark, to force it, this will make it grow quicker, and you will have a crop before it spreads, and cut it, and cover again, this would probably be the best method, just ensure you water it, and replace cover
