We have a bunch of potatoes with long sprouts from their eyes. (Actually, we just planted them, but I'll ask the questions I had right before planting.)
Should I leave a 12-inch sprout from the eye, or break some of it off? On average, the remaining potato chunk is small (<1"), so I imagine it doesn't have too much energy left.
Should I plant the sprouts up or down? (We actually planted them sideways because we weren't sure.)
