I have a question - how do those big ag companies grow zillions of huge potatoes? I'm sure they're not coddling them with extra compost, manures, fluffy organic matter, etc. And why do we hear reports of people being able to grow them successfully on the worst compacted messes by just placing them on top cardboard with covering them with straw? Potatoes have me baffled too. I've had great ones some years, and miserable returns other years. This year was a poor year as they got too hot too soon after being planted (which was late - my bad) and the tops fried off leaving me with only very small, round tatties. I'm thinking of just holding them all over the winter and trying again.
