Grow 100 lbs of potatoes in 4 square feet Answered
Learn how to grow 100 lbs. of potatoes* in a tiny plot with some lumber, potato seeds, and some careful watering. When I move into a new place where I can finally put my garden this is one idea I'd love to try out and see if it works.
And then I will be the Spud King of my neighborhood, giving potatoes to all the kids for Halloween because that's a lot more than I normally eat.
