Mary Stella -- for your bunching onions, are you thinking of planting seeds, or sets (tiny bulbs) ? I've never planted any of my onions in the fall, always in the spring -- but on the other hand, plenty of missed onions always survive the winter and sprout back up in the spring. The problem I have in fall planting onion sets is, they just aren't available to buy then, at least not where I live. And I don't know for sure, but kind of doubt that planting onion seeds in the fall in the north would work well -- if they started growing in the fall I think they would be way too tiny to survive, and if they didn't sprout until the spring I think you would get better results from planting sets as early as possible (and then making succession plantings to get a longer harvest of the green onions). And for growing regular large onions for storage, be sure to plant "long-day" varieties -- the "short-day" types are for our southern friends!!
