An onion that overwintered is beginning to form a flower bud at the end of a stalk. Should I cut it off to keep the energy in the onion to eat or should I let it form the flower? If I remember correctly, the onion will form seeds after the flower fades. Should I let the onion dry out before pulling it for later eating?

Most people do cut the flower off because it will sap energy away from making the onion bulb. But, if you would like to have seeds to collect and grow, you can leave it on. If you want to collect the seeds, you do need to let the seed pod dry before collecting the seeds.
