If you do want to plant them, be sure to use small ones. Sets larger than a half inch in diameter often split or send up flowers instead of making sound bulbs. For sweeter, larger, more interesting onions, prestarted plants are the way to go. The choice among commercial ones is paltry compared with that for seeds, but it s a lot wider than for sets. Whatever you choose, plant it now.
Onions grow best in cool weather.
