They say that one mans compost pile is sometimes the same mans accidental repository of tuber goodness. I can't remember how the original saying goes, but I think this gets close.
The above photo is our compost pile as of today. A few weeks ago we got rid of some pretty old baby red potatoes that had lots of eyes. Honestly forgetting about them we went to Nicaragua and left the garden alone for over a week. Imagine the surprise of returning to find that our kitchen scrap pile and straw mixture was now the growing grounds for 8 potato plants.
Besides being awesome, if this does not convince you that sometimes gardening could be done even by blind and crippled mice I don't know what will.
Wash it. (very important)
