I was inspired recently by an article from Wonder How To about how to re-grow vegetables. It looked like a fun and easy experiment to do at home with my girls.
We often have left over onion pieces at our home that I don't end up using so I thought this was a great opportunity to reuse it . Other vegetables we have successfully re-grown in our home are celery, garlic, and romaine lettuce.
There are several others examples for regrowing vegetables in the article such as carrots greens, mushrooms, and ginger that you might want to give a try. The article has great photos of each vegetable so take a look if it's hard to imagine what the re-grown vegetable might look like.
