Grow Green Onions in Water

March 5, 2012 by Lauren

Supposedly you just need at least 1/2 inch of root to grow and they should keep growing about 3-4 more times after you keep cutting them. I’m guessing sooner or later they’ll stop growing because they need more nutrients than the water can provide. But this is an AWESOME way to have plenty of green onions for a month and save money!

Mine just sat on the kitchen counter that doesn’t get any direct sunshine. Make sure you change the water every other day or so.
So there’s your way-too-easy-to-be-considered-a-project Burlap Bag project. Never throw away the ends of your green onions again!

(p.s. Sunee you are my bffffffff and I didn’t really think you were crazy. Ok maybe a little but I still think that.)

Time for an update!! Go here for an update on how well my green onions are growing!


  1. Vicki says:

    I tried this for over a week and I got nothing

  2. Mariah says:

    I’ve done this, and it works well for me, but after about 2 weeks the onions go bad. Any hints? Great idea, by the way!

  3. Lauren says:

    I’m only a couple of days into it – I’ve heard to change the water frequently. Also, the quality of water could effect it? Too soft, etc.

  4. Margaret H says:

    I’ve done this before (in a shot glass) and it worked so well! I was amazed!

  5. MYT CR8TiV says:

    I’ve done this before but I was putting the whole green onion stalk in a glass of water. I never thought about putting just the 2″ stems. I tried it on a bundle that was beginning to wilt. Cut off the wilted tops and left 2″ of white stalk. Left it over night and noticed about 1/4″ of green had sprouted out of the white stalk. I checked again and it got taller. I change the water every 2 days or so. But this really works. I’ve been noticing the stalks be grow taller like 1/4″ overnight. May take awhile for it to grow to full length but it’s sure fun to watch and observe.

    you can also place onion with the roots in a flower pot and dirt and they will continue to produce.

    just found your site and i am in love, lol, i found you thru pinterst. I love all the stuff you showed I think my favorite is the green oinon in water. Thanks so much for such a great site

  8. Debbie says:

    I love to do this too! After they started growing i replanted them in the top of my upside down garden, where I grow tomatoes. :)

  9. Arthur says:

    This is the post that brought me to this blog. This post makes me happy because I always hate throwing away the root of the green onion, but because I’m pretty sure I’m slightly OCD, I hate having white parts in my diced ‘green’ onion. So, now I know what to do with the bottoms! YAY!

  11. Tonia Berry says:

    Where I come from, we eat the white “bottoms”, and throw away most of the green part. It never occurred to me that people threw this part out.

  12. Linda Harlan says:

    Just make sure to change the water. I didn’t and it took a while to pinpoint that horrible smell that resulted! It was rank!

  13. Lauren says:

    Oh yuck, yeah change the water! We did every other day, sometimes every day.

  14. Nancy says:

    I agree with Tonya. I always use the white part and some of the green for color. I will try this for sure. Thanks!

  15. Karlee says:

    I wonder if they would keep growin if you used compost tea!

  17. Jenelle says:

    I was really excited to do this and after for or five days could really see growth. However I had to let my project go because the onion smell in my house was too much. Cool project though!

  18. Crystelle says:

    This is a really great idea and I will definitely try this! Thanks so much for thinking it up!!!!

  20. Brittany says:

    This is the post that brought me to your blog. I am sort of trying this out. We just planted our garden and had a few extra starter onions left. I put them in a cup of water today. In a week or so, I hope to plant them in the garden once there is a little more room for them. I also hope that they will grow better after a little drink. Thanks!

  21. This works exceptionally well with celery, also. It grows really fast.

  25. WINDY says:

    We eat the whole onion ,I think the white part is the best part!

    Just cut of the tips that are dead ,its good to go.

  26. Cleusa says:

    hi nice post, i have to comment to say your website is awesome, i’m glad i found your blog.

  27. Evelyn says:

    i wish i could write so good like you do in your posts.

  28. Barb says:

    I put mine in a cup in the fridge and they grow (probably more slowly than if they were on the counter) and don’t go bad.

  29. Louise says:

    This happened to me by accident in the refrigerator. I hadn’t expected it, and I didn’t change the water. My sister was a thrilled beneficiary.

  30. Tim says:

    Why do people think it’s so amazing that plants actually grow? Of course if they have roots they will grow in water, just like anything else. Not rocket science.

  31. Ann MacNeil says:

    we don’t throw the white part of the green onion, we fry them or eat them sliced up in salad the same things you would do with a white onion…but this is neat.

  32. I had never even thought of doing this! Though it does make sense. Sort of like putting a tomato in the window sill to help it ripen more… or something of that nature.

  36. Jodi says:

    I also eat the white of the onion. Would it work if I just cut off the root like normal and then put them in water? I tried that and got a funky smell in the kitchen. I changed the water everyday so next time might put it outside.

  37. Anabella says:

    I am so glad I found this post! I use green onions all the time and had some in the fridge when I read your post. I dropped them in a cute glass container and have been growing them ever since. I have cut them about four or five times and they are still growing back (haven’t lost any flavor) so I love this idea!

  42. Connie L. says:

    This works predicated on the fact that you only use the GREEN part of the onion. Most people, including myself, use the white part as well in cooking, sauteing, etc. Which leads me to wonder if people assume that, because they are called “green” onions, they should only use the green part…The white part is the tender “onion” part with the most flavor. I often don’t even use the green, as it’s sometimes tough and doesn’t cook down in recipes.
