My plan is to grow 4 different kinds (early, mid, late and fingerling) in 4 dark plastic garbage cans (with drainage holes of course). The tire method didn't work for me because my ducks kept noshing on the leaves and so the plants didn't really get a chance to grow. I'm going for: Buffalo Red Ruby, Yellow Finn, Baker King, and Ozette. Then when it's time to harvest, I'll just put the lids on the garbage cans and wheel them around to the north side of the house: instant root cellar.
(Maybe I should empty out the soil and straw and put them in nice clean pine shavings or new straw in the cans...any comments?
