Double or triple your return on scallions or green onions. Save about two inches of the stalks near the root and stick them into a cup filled up to about an inch with water. They'll regrow for easy, free, and deliciously fresh new scallions ready for cutting right at your kitchen window. You don't even need soil for regrowth, but replanting them into a pot or the ground is also an option.

I would like to know if what I read works. I read that on the little onions, the ones with long green stalks, if you save the cut bottoms with the roots and place them in water that they will grow and you will have an ever ready supply of onions. Do any of you have any experience with this?

I know that you can grow onion in water indoors in the same way you grow Hyacinths in water. It is very nice in the winter.You cut the green stalks to use in salad and they grow again. I don't know if you can start onion from cuttings of the rooted bottom part.
Hope this help!
I tried it!
The new growth is the part above the lid of the jar!
