Can you tell me more about growing onions from the bulbs? I usually cut mine fairly close to the root growth at the bottom, maybe leaving 1 cm of onion white, and throw it in the freezer with other veggie scraps to later boil and clarify for broth, but I am CONSTANTLY buying green onions for soups, dumplings, stirfries, grilling, what-have-you, so I’m very interested in this idea. I live in apartment with a bay window which is ripe for a planter, so this sounds potentially very useful.
