Harry thanks for the reply. I tried this spring with seed potatos using a 40 gal. barrel instead of tires. I harvested approximatly five pounds of new potatoes for my effort. I think maybe it just gets too hot down here too soon. Yea, finding good seed potatoes is a bit tough. I got mine from a neighbor who had ordered them from a seed catalog. I'll try again but in a raised bed this time and in the fall. Thanks again, Allen
