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.
Just used some spring onions in dinner tonight, have saved the stalks and will try this! Pop a post it note on it asking everyone not to throw out and hopefully I get similar results! Will post a pic in one week :)
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!
Green onions can be grown in a jar of water on a window sill. All you need to do is stick the roots & white part in some water & change it out every few days. (Or you can plant the bulbs once you cut the green parts off & they'll re-sprout green parts
