Cut the white part of the green onions, leaving the roots attached.
Place green onion cuttings in a jar with just enough water to keep the roots submerged.
Set the cuttings by a windowsill for some light. Change the water every 2 days and watch them grow!
In just about 5 days, you’ll have new scallions! At this point, you can plant your new scallions in your garden or in a container with good potting soil. Cut them as needed for your dishes.
