Step 1

Slice carefully into the onion lengthwise to expose the center sprout. Be careful not to cut through the root of the onion.

Step 2

Begin peeling away the onion's layers, until you just have the center sprout remaining. If there are multiple sprouts like this one, separate them into individual onion sprouts.

Step 3

Place the onion stem into a small container of water and give it a few days for new white roots to start sprouting.

Step 4

Once you have roots developed, transplant the onion into the ground or a container filled with quality potting soil with the root end down. It's best to plant the sprouts further apart from each other than pictured.

Step 5

Let them grow through the gardening season. Onion plants are done growing when the bulb emerges from the ground and the green sprout starts to wilt and brown. Pull and enjoy your new onions.
