In one of my many information seeking trips on the internet, I came across a very interesting reference about regrowing onions using the bottom rooty part of the discarded onion. Talk about recycling. Well I just had to try that neat idea. The biggest problem is to remember to save that bottom piece instead of throwing it into the compost bin.

Onions regrowing, 3/7/2012
So cut off the bottom piece of the onion that contains the ring of little nubby roots. I sliced about 1/2 inch off the bottom. Indent that piece into damp soil, not wet. Leave the cut side above ground level to avoid rot. Water as needed to keep moist.......Wow. That was pretty easy. And exciting. One of the cuts is even going to make two new onion plants. I will separate that to two plants. Talk about a perpetual growing machine! I am going to put them outside soon, as onions can certainly take this weather.
