they sell spanish onions sets..........start this fall by preparing your ground for next year....spread dried cow or horse manure and some lime..........turn with a machine or by hand.....break down the soil. It is much easier doing this with a machine. We also put 20 bales of hay in the mix. We covered the whole plot with black mess for the garden and then covered this with grass or you could use hay........we planted the onions on the edge near the fence. Animals don't like them.
