It has been said here before: I do not have a green thumb. Nor the patience required to tend a lovely garden. But oh how I *wish* I did!
But potatoes? Those are easy. Plant them (we did it in a bag.) Put it in a place where rain and sun reach them, watch the vines grow and eventually die, then dig for potatoes. Perfect for me and me lazy brown thumb. And Job loved the dirt digging too.
