Autumn Planted Onions

The principal advantage of planting onion sets in the autumn is that your onions are ready to harvest around a month before spring-sown onion sets are. Also, because they are harvested around a month earlier, you can potentially immediately follow them with another crop that would be too late to plant a month later. Sweet corn and winter squash for example. For a good yield, onions need moist soil when they are bulking up in Spring.
