Dig your fingernails into the skin at the top of the onion bulb and rip it off piece by piece. Discard the skin when you are done. The sprouts grow at the center of the onion bulb. Slice through onion’s layers vertically while avoiding the sprouts. Repeat on the other side then carefully slice off the onion's layers.  If you don’t have a knife, peel off the onion’s layers individually with your hands. You can eat the onion layers if they are firm and crisp, though make sure you wash them first! If they are soft and mushy discard them. You will likely find a few sprouts growing at the center of the onion bulb. Some will protrude from the bulb, others will not. Use your hands to gently separate the sprouts from one another so they don't need to compete for space. Given proper care, each sprout can grow into a brand new onion bulb! You can keep the sprouts in individual cups, glasses of bowls of water. Within a few days white roots will form at the bottom of each sprout.  If white roots are already present you can plant the sprouts straight into the soil. If you see dry, brown roots on a sprout, it means they are already dead. You want to wait for new white roots to form.
