Onions are one of those plants I want to master because I like to eat them and they store very well. I've experimented this year with growing them both in the ground and in containers with some success with both methods. Now that its turning cold I've been thinking about my Winter gardening inside under lights.
I have two containers with onions sprouting and will see how they do. They may have too many onions in them to grow some bulbs of eating size but I have been wondering how to grow the small bulbs (aka onion sets) that I bought at the nursery this Spring. More research is called for.
I came across this article which mentions two methods for starting onions.
I don't know why I didn't realize that the cut off ends with the roots could be replanted. It makes perfect sense.
