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.”

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.
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! 🙂
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!
Thanks, Christie! I do that too… isn’t it SO nice to always have green onions on hand for cooking and garnish? 🙂
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.
Thanks, Janie… I’m so glad to hear you’re enjoying the fun, frugal tips! 🙂
How did you regrow the leafy greens. I missed something. What about carrots.
You can regrow carrot tops but they’re only decorative. They don’t reproduce more carrots. Seems a bit pointless to me.
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!
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.
