How to Regrow Green Onions! ~ Diane's Vintage Zest!

How to Regrow Green Onions!

If you didn't know by now, I'm a city slicker through and through.  It was only after college that I started to sew, craft, cook from scratch, and DIY things myself.  Thus, it is no wonder that I never learned how to grow fruits, veggies, or herbs, although now it is totally at the top of my list of things that I would love to learn.

Even though my mom has a great garden, I did not inherit her green thumb.  Also, it's only now that I'm older that she started growing all of her tomatoes and everything!  However, I have one advantage over her.  I love to recycle and will try to find a use for everything that I can!  Vegetable scraps become vegetable broth, destroyed camisoles become maxi dresses, etc.  Basically, I hate throwing things away that may one day have a use.  That's how this post came about!


This is possibly my easiest tip ever and a great one to do with kids!  Learn how to regrow green onions lickety split!

On Instagram a couple of weeks back, I shared this picture with you.  It was a set of green onions that I placed in an old takeout container, growing some fresh green shoots!  Exciting!  How did I do this?

There really isn't too much of a process here, just a few tips to help you start growing!

  • When you cut your green onions, make sure to leave a couple of inches up from the stem.  If you're in doubt, leave more.
    • On my first batch, 3 of the 6 didn't grow, on the 2nd batch, only 1 of 8!)
  • Fill a container with water.
    • Although I used a flat takeout container first, I got better results using a bud vase and an old peanut butter jar.  Next time, I'm using a Mason jar!  Maybe it's better for the roots?
  • Leave on a sunny windowsill and let grow!

They will grow FAST!  Make sure to change the water often, especially at the beginning because it will become slimy from the outer layers of the green onion.  Later on, just make sure that your plant has enough to drink and it will grow, grow, grow!

The green onions on the right were cut down to the nubs less than 2 weeks before!  Amazing!

Later on, I'm going to experiment with replanting them with soil outside.  For now, I love having a lovely bit of green on the windowsill, and it's so convenient to reach over and snip the top off for a little bit of garnish.



  1. That's a great idea Diane! I'm always going through green onions like crazy. - Tiffany PS. I haven't commented here in awhile because I forgot my disqus password - but I remembered today! :)

  2. I know! I almost have too many know, and I don't know what to do with them!

    P.S. - Don't worry about it, because my guy constantly forgets his password and I have to talk him through all of the possible ones he uses. :)

  3. This is awesome! Do you think I could do this in colder weather?

  4. I have no idea, but it's worth a shot! Definitely a lot of sun is helpful.

  5. I know, right! Isn't this fun! I feel like such a frugal homemaker when I reuse my green onions!!!

  6. I need to find more easy tips like this!

  7. I love growing things. I will have to try this. Great tip. Visit from Whimsy Wednesday.

  8. Love this! Last year I accidentally grew a bunch of green onions from a batch I got at Trader Joe's. They just kept growing and growing, so I let it happen. But I regret to say I never actually kept it up. Totally happening now!

  9. Thanks! I'm looking for more things to grow now too. :)

  10. Ha! It was gardening through laziness, something I've been guilty of too! It's even more fun when you grow it on purpose. :)

  11. I love this idea! I have tried it in water and soil -the ones in soil didn't live very long, but the water ones regrew many many times! They got extremely stinky after a month or so though, so I dumped them and started new ones. Have you had any trouble with them being smelly???

  12. Diane,

    What a creative way to regrow green onions. I never thought about using this method before. Thanks for sharing. :)

  13. I have always wanted to try this!! Just wish I did with the ones my garden grew this summer! :)

    Again, thanks for joining the Link Up this week!

  14. I need to remember to do this! Even thought green onions don't cost much, a penny saved is a penny earned right! Thanks for linking up to Gingerly Made's Show & Tell party!

  15. I would change the water very often because I noticed that it happened the first time I ever tried regrowing. Now, instead of adding new water to the old water, I pour out the old water and use new fresh water. It is completely stink free now!

  16. Now I know why they're so cheap! They grow like weeds, so maybe we should switch up the saying to "grow like onions!" For me, the best part is not having to run the store when I need just a few snips. :)

  17. Great idea! Thanks for sharing at the HomeAcre Hop!

  18. I always do this every time I have an extra green onion when I cook but it always end up slimy and rotten after a few days, maybe after reading this I'll try it again.

  19. Great! Good luck this time around. :)

  20. You know what ? Your website is amazing. I couldn't help myself looking to all categories in the header bar . I took too much in my tour more than any blog I visited. It is well categorized and designed.

  21. Yes! Love saving every little bit I can. I'm curious to know if you are able to replant in soil. Thanks for linking up to Gingerly Made.
