Last year I planted 3 types of onions from seeds and none grew?
I am getting my garden ready for winter I plan to have a 30 ft row of onions.
What is the best way to grow onions from seeds?

Besides Walla Walla which is the only one I had heard about, Candy and Bridger are also killing freeze hardy varieties, according to this article:
