You should order and grow enough onions so you have some for eating and some dedicated for seed saving. Onions can cross, so it's best to start with one variety at a time. Plant your onion seed and do not pick or eat the ones you intend to harvest for seed. At the end of the growing season when the onion tops are brown, drying and bent over, harvest the onion bulbs. This should be done before the first frost. Do NOT wash the onions, however you can shake the dirt off.
