Cut off the roots to a green onion and plant it in dirt and water it well. You can directly plant this in the garden or in a pot for onion access year round. You can even plant them in a flower pot in a sunny window. In a few weeks you will have tons of green onions for the picking.

This could save some money, especially if you can't use up green onions before they spoil....like me.
