My son planted 4 acres of Milo and Sunflower last year around mid April. Almost to late to plant in this part of the country. The rains were far and few between making for slow growth. The Milo finally made a good crop, but the Sunflower was inmature for the most part. With no cultivation there was lots of grass in the middles, and as dukkilr said it didn't attract near as many dove as it could have.
