How to Regrow Green Onions from Kitchen Scraps

Green onions are about one of the easiest kitchen scraps to regrow.

And they grow fast, which is fun to watch!

I love garnishing food with green onions, so why not grow them myself rather than continually buying them from the store?


Leave about 1/2 an inch to an inch at the bottom of the store-bought green onion.

Starting size

Place it in water, just covering the roots. You don’t want too much water or the stem will get slimy and smelly.

1 week after starting

You will see the center start to grow within about a day. Within a week, you should have a good bit of green stalk starting to form.

You can pot your green onion in soil once the roots are well established.

3-4 weeks after starting

Within a few weeks, your green onion should be almost full size.

Stages of growth

Harvest, leaving at least one leaf on the plant to keep it producing.


One question I had when I first started using this method was, “Will the bulbs get large like regular onions?”

Well, the answer to that question is “no.”

They definitely get larger than they come from the store, however do not get any bigger than a golf ball.

Mystery solved!
