I didn't do this on purpose the first time. This year, well, yes, I did purposefully put a few chunks of potatoes that were growing eyes like crazy in the pile of mowed leaves reserved for the compost pile. I did it because it's rather fun to "dig" potatoes in a pile of leaves, and never mind they don't get very big. (Most are not any bigger than the end of your thumb.)
OK. I could have waited a couple, maybe even a few more weeks, but I couldn't resist pulling them out today. They'll steam up nicely and it looks like there's enough for more than one meal.
I'm not advocating growing potatoes this way, but I think it's fun to do with a couple each year just to see if they will grow.
