The guy who grows this does a lot of different things (his wife is there, too, but only occasionally). He once explained that there were different kinds of キビ, drawing the characters on the ground with a stick. He's one of the friendlier gardeners/farmers around, and once gave me a huge hakusai. He's meticulous to a degree that other gardeners aren't--they way he lays out rows, pulls the dirt up onto negi, covers starts with netting, etc. The millet is certainly done & gone, but he has daikon and broccoli in as of a week or two ago.
