Peanuts are the strangest thing in most vegetable gardens. They flower above ground, self-pollinate, and then the fertilised flower sends a stalk called a peg downward, which pushes into the soil and forms the pod underground. Nothing else in the bed does this, and it explains most of what peanuts need from you.
