How to Regrow Green Onions from Scraps

If you have a jar, water and a window sill, you can easily regrow green onions (a.k.a. scallions) to save money and energy.

Since regrowing food from scraps is like buying one and getting one free, it’s a money-saver or a reason to buy organic, which at my grocery store costs about twice as much as the conventionally grown product. It’s also an effortless way to give a second life to a product that initially took a lot of energy to grow, harvest and ship. That is particularly appealing to me because I’ve never seen locally grown green onions at a farmer’s market or gotten them in my CSA. Regrowing my green onions gives me a chance to make a local product from the leftovers that would normally end up in the trash or compost.

To regrow green onions:

  1. Chop the green parts like you normally would, leaving the white part at the bottom.
  2. Put the white ends in a jar and cover the roots with water.
  3. Place the jar on a window sill and be sure to keep the plants watered. Also remember to change the water a few times a week to keep it fresh.

It took about 10 days for my green onions to regrow. I have also regrown the plants a second time but the roots got quite long and unwieldy. At that point, it may have been better to put them in dirt.

Sticking wilted green onions in a jar of water s also a great way to revive them when they are a little past their prime.

    I had no idea you could regrow onions. My favorite part is that it only takes about ten days so I’ll know fairly quickly if I’ve done it right. Thanks ladies! I’m going to try this!
