If you really want a bunch of potatoes in a limited space:
Get some used tires that are all the same size (any tire store will be happy to give them to you)
Drill holes in the sidewalls so the tire will drain of water when lying on their sides.
Fill a tire with dirt, and plant three potatoes in the middle in a triangle about 4" to a side (this assures that you get a viable plant).
Put another tire on top. Water
When the plants get tall enough so that 6 to 8 inches of the plant will be above the top tire fill it with dirt.
I've read studies on this and used tires don't put out anything that's measurable. So no worries. -I was considering using tires to build a structure near the spring I use for my potable water on my land. Some of the studies I read were about used tires being actually used in water and the CDC and EPA both said it was a safe usage.Originally Posted by Almeria

We did barrels this year. They are growing well so far and we're about to put another layer of dirt over them soon. We got the barrels for free from a guy who makes eco-friendly soaps and he donates them to the boys and girls scouts every year for their rain barrel project that they do around here.
