Never again will I buy green onions from the grocery store! Ok I still will sometimes, but certainly only once every four to six months. Here is why:
I was looking through Pintrest the other day and I saw that you could grow the green onions you got from the grocery store just by placing them in water! Well after dinner one day as I was about to throw away my onion ends, I stopped myself. I grabbed a cup out of the cupboard and put them in it with a little water and forgot about it.
Well, three days later the green onions had doubled in size! Less than a week later I decided to plant them. They started out less than three inches long and now one is almost a foot long! I can't believe it. Yay free produce and Pinterest!
