I'm always buying green onions, now I won't have to! Grow your own green onions.much faster than celery. Next time you buy green onions, save the bulb and toss it in a jar of water.you'll have a whole new bunch in 12 days!
Regrow Green Onions Indefinitely Take two or three green onions and place in mason jar with fresh water. Cut off what you need from the top and watch in amazement as they regrow themselves over and over again.
