Just wanted to share this in case it could help any of you: I found and ordered from
Sunbelt Transplants last year -- finally a reliable source of organic onion plants. Buying from them has hugely simplified early greenhouse shuffling and made our onion program much better than ever before. I highly recommend them. I'm certain the price more than compensates for lengthy time holding onions in cells, worrying about heating greenhouses early season, etc. Hope everyone is doing well!
