I planted 12 onion sets from Sunrise today. There are four white, four yellow, and four red, all in a nice pretty little 2'X2' plot. The helpful man at Sunrise said to plant them with their little tops sticking out, so I did. Supposedly they will get nice and fat and kind of push themselves up out of the ground that way.
We tilled last weekend so the ground was so nice an easy to play in.
