How To Grow Potatoes

It's EASY to grow stuff in straw bales. I planted a piece of a potato into a straw bale, right on top of concrete (where I had no soil, no soil container, etc), and sure enough the spuds grew fine. They should be ready to harvest in a few weeks. It will be super EASY to harvest, since I won't even need to "dig" for the spuds, just use my hand to pull them out of the straw... what could be easier? :-)
