I bought some green onions the other day to be used in some salsa that I was making. I didn’t need to use the whole bunch so looked online to see how to best store my remaining green onion tops. This is when my newest experiment developed. I found out that you can use the roots of your green onions to regrow more, simply by putting them in a glass of water! I love how easy this is. I started my experiment on Tuesday, and look how much they have grown in just a few days! I keep them on my windowsill so that they get some good natural light and have changed the water once so far.
