We ordered a "potato bin" from a gardening catalog a couple of years ago that promised "60 POUNDS of potatoes from one plant!" Yep. Uh-huh. We watered and babied, and babied and watered, and tended that bin lovingly all summer. Come harvest time, we opened the sides to collect our 60-pound bounty. We got ONE potato. About 6" long. (Don't ask ME!!!)
