|I bought a yellow onion at the market that sprouted a few days later. I have planted it in a deep pot with organic soil and keep it in a location with direct sunlight through much of the day. My question is, what now? The green stalks look like green onions, is that correct? If so, should it be harvested as green onions, or will the bulb produce other yellow onion bulbs to be used next year? If so, what should I do? I've never planted onion before and am having a hard time finding any information about stages of growth, harvesting, etc. Thank you!
