I took another stab at re-growing green onions in a cup with water after reading the information again and figuring out what I had done wrong the first time. My mistake was treating them too delicately,like herbs (cutting off a green stalk here & there).

Instead, what I needed to do was just whack the entire thing off near the top of the white portion, and then place the root end in a cup with a bit of water. Voila - regrowth starts right away.

Where we live green onions are 68-cents a bunch which I think is really expensive for something that yields just a handful of garnish. Yes, they are tasty and have nutritional value, and there are some dishes (like noodle soup) that they really elevate, but you can get much more nutritional bang for your buck buying other veggies so we very rarely bought them. Now they are back on the menu! As you can see, all the space you need is enough for a glass or two. We decided to go with 2 bunches so we'd always have plenty grown out on hand.



P.S. - I've heard that they lose flavor after a couple re-growths, but still this is a way to stretch a bunch 2-3 times over.
