Magic Onions

I’m sure many of you have seen the pin on Pinterest about the magic regrowing onions. You know, this one:


I’ve seen a lot of pins that end up being too good to be true so I wanted to test this one and see how good it was. So after I used up the entire tops of some green onions making a meal for the Chinese New Year, I popped the bulbs into a glass and added a cup of water. I wasn’t a believer but they were just going to end up in the trash so why not try?

I woke up the next morning and gave it a look. WOW! That was just 12 hours and my onions were already shooting up. It took about 7 days but they were right back to the old height.

Some Tips

  • Change the water daily. It will start to stink fast.
  • After 14 days if you still haven’t used the onions then place them in a plastic bag in your fridge so they don’t get out of control.
  • You can reuse the bulbs multiple times. The bulbs do get fatter so just cut a bulb in half if it gets too big.

Onions don’t cost a ton but I save the most on time, I don’t find myself needing to run to the store for a single ingredient when I can grow it in my Missouri kitchen in the middle of winter.

    Hi! How much sun are these getting? Are they in a window box? Or do you set these outside? This is a great idea and I have lots of leftover onion bulbs I needed to use up!

    When I cannot be bothered to remember to change the water, etc I just replant them in the garden and they regrow there as long as it is the right time of year.

    I cut a green onion down to the whites, and wondered if I could regrow them. Now I know! Thanks! 🙂
