Have you ever grown a huge amount of onions? Successfully? I need your words of wisdom. Dixondale Farms sells onion sets at a great price (ex.-1800 for under $60). I am very tempted but I've never grown onions. How difficult are they to grow? I'm in NY, chilly, wet spring, beautiful summer growing weather. Decent but rocky soil. Forgot to say that a lot of these would be harvested as scallions.
