I have harvested the Walla Walla and the red Mars onions. I planted 24 Mars 128 Walla Walla. The picture only shows some of the best ones. The Mars crop was fair but the Walla Walla crop was poor. In the ten years I've been growing Walla Walla my success rate has been outstanding. I'm blaming it on way too much hot, humid, and wet weather.
My 280 Copra onions are still in the ground and seem to be doing quite well so far.
