Awhile back, a friend had told me that once you’ve used your green onions, you can pop the ends back in the water.
Strange, I thought… but what would it hurt to try?!?
How Do You Regrow Green Onions?
It’s simple! You’ll just need…
- 1 Bunch of Green Onions
- 1 Small Jar or Glass
- Water
- Bright or Sunny Windowsill
Here’s how it works…
Off to the grocery store I went, to buy a little bunch of green onions…
It just so happened to be taco night, so choppity-chop-chop-chop I went…
Now down to the little stubbies, I just popped them in a jar of water.
Yes, you could use a little glass too, but you know how wildly in love with mason jars I am! 😉
Then I placed my jar in my kitchen’s bright, sunny windowsill.
The key is to change out the water every day to keep them happy and fresh.
After about a week or so, look what had happened. Whoa!
Several days went by, and they just kept on growing!
So every time I was in need of some green onions ~ to add to my Easy Salsa Recipe or garnish my Crockpot Apricot Chicken with, I simply grabbed from my jar and started chopping!
Then the weirdest thing happened… they started growing AGAIN!
I think I grew about 3 rounds of green onions off one 50 cent bundle.
Not bad! 😉
Can You Regrow Green Onions in Soil?
Why yes… yes, you can!
If you want to have fresh green onions even longer, you’ll eventually want to transition them to soil!
After the 3rd time of regrowing my green onions in water, they seemed to be losing a bit of flavor, so I took the old stubs and planted some in a pot inside and planted the others out in the backyard.
They had developed a great root system sitting in water for those weeks, and started growing like crazy again in the soil!
Now I have some handy inside and outside at all times! And when I’ve need more, I’ve just grabbed another 50c bundle from the store, and started the whole process over again!
These are the potted ones I keep indoors near my sunny kitchen window…
And here are some more I have growing out in my backyard next to my Romaine Lettuce…

Rebecca writes: “I love doing this. You can do this with larger onions too and cut off the tops to use like chives to add to dishes. I’m actually doing this with red onions right now. I had one I used half of, then it went bad. Stuck it in water. Had three sprouts that are now planted in a large pot and growing happily.”

Judee says
More than ever, right now it’s important to really know how to keep produce fresh since we can’t get to the store that frequently and have to buy double. I tried the green onion growing. It grew for 10 days and then the outside turned to almost paper and it stopped growing. I wonder how long it can grow for? what’s your experience with the re-growth time.
Heidi says
Hi Judee ~ it really is so nice to have them in the kitchen or garden ready for any recipe! When I regrow mine, I usually regrow them 3 full cycles inside in water, and then move the stubs outside to the garden. I’ve had mine last easily in the garden here in Phoenix for 6 months – 9 months. Just make sure they get plenty of water. Right now I have some growing inside in water, inside in a pot, and also some outside in the garden. It just hit 100 degrees here, so the ones outside have bolted and are going to seed. I’ll collect the seeds from the flowers and then plant those again later. Hope these tips help! 🙂
Christie says
Love that you’re sharing this! I do this all the time and once they get long enough I replant them in soil for more haha!
Heidi says
Thanks, Christie! I do that too… isn’t it SO nice to always have green onions on hand for cooking and garnish? 🙂
Janie says
I really enjoy all of these ideas. When your really penny pinching this is always a good idea. Thanks and keep it going. I’ll be looking for more ideas.
Heidi says
Thanks, Janie… I’m so glad to hear you’re enjoying the fun, frugal tips! 🙂
Tammy Littau says
How did you regrow the leafy greens. I missed something. What about carrots.
Fiona says
You can regrow carrot tops but they’re only decorative. They don’t reproduce more carrots. Seems a bit pointless to me.
Fiona says
But I’ve done the green onion thing, they go mental if you plant them directly into the soil and keep on giving! Also garlic, yum!
Denise Jones says
My green onions are 6 inches tall after sitting in water for one week. I change the water every three days or so and my husband and I are amazed with the results. No more throwing away of such “recyclable” goodies. I even have romaine lettuces and celery sprouting up and look forward to harvesting these as well.
Erin says
I’ve done this with lettuce, but now I have more ideas.thank you!
karla says
I’m also confused on the regrowing green onions. I always use the white part too. Do I use just some of it and put the remaining part in water?
Heidi says
Hi Karla ~ yes… leave some of the white and the roots remaining, place in water, and watch them grow! Enjoy! 😉
Tedda Cooper says
I have grown pineapple several times by cutting off the bottom about an inch up and planting it root side down. It takes about 3 years before you get a pineapple, but it was delicious!
Ruby Henley says
Thanks for the tip. This will save me money.
Patricia says
I’m going to do the green onion thing also! And celery. I know you can make a nice potted plant out of a pineapple top,by slicing off the top and keeping it in a saucer or shallow bowl of water, but it has never worked for me. I’d be glad to hear from anyone who has suggestions…I love the idea of keeping veggies alive. This is my first visit to this site, and I’m really glad I stumbled into it. 🙂
Brenda says
I’ve grown pineapple plants from pineapple tops many times. I use a pot of miracle grow potting soil, not water. I cut the pineapple about an inch down and then make a hole in the center of the soil, put the top in soil, cover completely, leave the green leaves out of course 😊. It loves lots of water, especially while it is establishing it’s root system. So plenty of water and sunshine. I’ve heard after four years you actually get a pineapple. we got a freeze here in Florida this year and I was away and didn’t get to bring mine indoors and lost them. I’ll try again, they grow fast in the right conditions. Some say to take the pineapple meat and rind off before planting, I don’t, it seems like it fertilizes the soil. Hope you try and succeed.
Gloria says
I’ve had pineapples growing in my yard for years. I just cut the top off about an inch down, set it where I want it to grow, and it always does. I have sandy soil here in FL and rarely water them. They love sun. Pineapples are very easy to grow. My only problem is beating the possums to them. PS. I’ve also grown regular onions from planting the roots from the scraps. I cut those about a 1/2″ up or so. They like sun too, and watering.
Linda Woodhead says
Keeping cilantro in water helps keep it fresh
Marie says
This is so cool! I do the same thing with celery!
Heidi says
Wow ~ I didn’t realize it worked with celery, too! I’ll definitely give that a try as well. Thanks for sharing, Marie! 😉
Laura says
With celery cut the bottom off leaving about an inch. Put the piece in a shallow dish of water so that the piece is submerged about half way up in the water. The outer stalks will harden over but you will begin to notice the inner leaves beginning to grow after a week or two. Change the water every other day or so. Plant in the garden or in a container on the window sill and it will regrow.
Sarah says
I used to do this, but then I decided to plan them outside in a dirt patch outside my kitchen and they have been growing like crazy and never lose flavor! Love that I can cut off what I need whenever I need it!
Leslie Hoyer says
I have green onions in a jar on my kitchen window seal right now. Just like yours. Pretty nifty
Amanda says
I did this too but first only because they were wilted from being in the fridge. Wen they rooted, I stuck them in a container with soil. I now have three containers of green onions outside in my garden.. They multiply like crazy… And some of them are really tall too!! I had to change the water a couple times I think, kept them in the kitchen window until ready to transplant…
