How to grow green onions in your kitchen all year round

Updated on May 8, 2013

Extend the life of green onions by regrowing them

How often have you chopped off the green stalks from a bunch of green onions or scallions and tossed the white bottoms in the trash? Did you know that the white bulbs when set upright in a glass of water will regrow when placed in a sunny location in your kitchen or windowsill. This will keep regrowing all year round in your kitchen and is very handy when a recipe calls for it. Just chop off what you need and keep the white ends in the water to regenerate again.

All photos were taken by Bakerwoman (that's me)

Does this look all too familiar? - White bulbs of green onions are often discarded after being chopped away from the green stalks

Do not throw away the white ends of the green onions as these will regenerate new sprouts and reward you with new growths for your next recipe. Save money and let your green onions keep growing green onions for you. It will guarantee not to make you cry.

Regrow the green onions in a glass of water - Here is how to do it

Set the white bulbs upright in a small glass, vase or mason jar with enough water to cover the bottoms. Place in a sunny location in the kitchen or windowsill, replenish with fresh water every 2 days and watch the green onions grow.

In this picture, the white bulbs have rewarded me with green onions in just 2 weeks. Thread-like white roots shoot out of the bottom of the white bulbs which drink most of the water. This is a good reason to keep the glass filled with 2 inches of water at all times.

The shorter growths are only 2 days old and were added to the growing medium after these were used as accompaniments for my Schezuan Mapo Tofu dish.

Of course, you can plant these in the soil but it will still need to be watered. My preferred way is the simplest way--placing the bulbs in a glass water.

Do you have trouble keeping unused green onions fresh in the produce drawer of your refrigerator? - The answer most likely is yes

More often than not, the unused bunch of green onions are forgotten in the vegetable drawer of the refrigerator. It takes a backseat to the carrots, potatoes, celery stalks that can last longer. By the time a recipe calls for green onions, you reach into the plastic bag and find the stalks wilted, slimy and ready to be tossed out.

How to keep unused green onions fresh in the refrigerator.

1. Wash green onions and pat dry of excess water - Fold paper moist paper towel over green onions

I use the same paper towel that was used to dry the bunch of scallions to keep them moist. This method is good if the green onions are going to be used within a couple of weeks.

Another method is to stick the green onions in a glass of water covered with a plastic bag in the refrigerator. I do not recommend this as it takes up to much space in the shelf and will inadvertently be knocked over.

2. Store the washed green onions with damp paper towel in a resealable plastic bag - Store in the refrigerator until needed

Re-moisten the paper towel when dry and reseal in the plastic bag. Store in the refrigerator drawer until needed. I have tried this and the green onions stayed fresh and firm for 2 weeks.

Freeze chopped green onions stored in a resealable plastic bag.

Another useful tip: Freeze chopped green onions in a used plastic water bottle. This makes dispensing so easy when you need it. Read about it here.

      I've been using this technique for a while. I love to make fresh homemade ramen and green onion is a big ingredient in my food so. Hope everyone else grows a much of your own food as you can! ;) Eventually we'll have some healthy unadulterated vegetables again.

      I always chopped up the white and used it. I can remember my mom taking an onion, cutting it in half and putting it in water. I like this way better because the bulb is smaller. Thank you.

      I've never heard of throwing the white part away either. It's too good! But I love the idea and will definitely try this.

      Hmmmm. I always use the green and the white. I didn't know you could regrow and I hate throwing anything out. So the white part of the green onions usually goes in my scrambled eggs. Thanks for the tip. I'll definitely try this.

      We regrow green onions in a pot on our balcony. Never thought just to stick them in a jar of water. I'll try that next time.

      The white part is my favourite bit so unfortunately I won't have any to regrow but i''m glad to know that this can be done.

      Great tips - much better than just throwing them away.

      When I get a kitchen with a window I'll sure give this a try.

      I thought I was the only one who did this! Great pictures, and thanks for the links to the benefits of green onions. Fascinating.

      What a brilliant idea, I'm thinking green onion sales are about to go down when we are all growing them in our own kitchen....and they are pretty with a sculptural feel as well. Adding moister with the paper towels took me by surprise too. Congratulations on your Short and Sweet feature! :)

      As I have basil growing in a bunny mug on my windowsill right at the moment, I will definitely be adding green onions to keep them company. Thanks for the obvious and great advice!

      This is so great because I grew up eating green onions with dinner, my mom used to buy them all the time and keep them in a glass full of water too. LOL

      I never knew you could regrow green onions like you show. I am going to try this for sure, I use scallions all the time. You got to love Squidoo for all the wealth of knowledge that people have! Thanks for sharing.

      I am on my way to get my scallions and place them into the water. There will be no more thrown away. Thanks for sharing.

      Great idea! I cut up the bulbs and toss out the green parts. Now I can save the bulbs to grow more onions.

      @LiteraryMind: @LiteraryMind, I'm so glad you stopped by and perhaps you will let your green onions grow green onions for you in your kitchen.

      What a great idea. Green onions always are sold in larger bunches than needed for any recipe I have. I always wind up throwing some away.
