Regrowing green onions from fridge scraps will save you $1.99 a month! That’s $23.88 a year. Whoo Hoo!!!
Okay, this might not make you rich and it won’t change your life, but it’s something you should try just for fun. It is truly amazing how quickly your green onions will regrow their green tops with just water and a bit of sunlight.
There are many other kitchen scraps you can regrow or seeds you can start, but none are as quick and practical as green onions. Within days, you’ll see results and within weeks you can use your regrown onions – that apple seed or avocado seed is going to take a lot longer! Two other scraps I like growing are celery and romaine.
Step by Step – How to Regrow Green Onions
- Start with a regular bunch of store bought green onions – organic or not – your choice.
2. Cut the onions so there is about one inch of white root end remaining. Place the root ends, root side down in a small glass (shot glasses work well). Fill with water.
3. Place on a sunny window ledge and replace water ever 2 to 3 days.
4. Enjoy watching how quickly those greens will start to regrow (here’s Day 6).
5. Once they’re 2-3 inches long, you can cut the greens as you need them and keep the roots in the water. They will continue to regrow.
6. Over time, you’ll want to clean up your green onions. Trim the roots and remove any dead layers on the outside of the onions.
How to Plant Your Green Onions
If you’d like to give your green onions a more permanent home and have them last even longer, transfer them to a small pot filled with potting soil. This gives the green onions some nutrients and will make them stronger. If the weather is consistently above freezing, you can even transplant them into your garden.
I often start them in water, but because green onions come with roots in tact, you can actually plant them directly in the soil when you get them from the store. That’s what I did with this pot.
How cool is that?!
