I am a part time lawn professional. I only work on a few jobs per year in central Oklahoma. I have a customer who wants to have a mix of the scotts hybrid bluegrasses seeded on his lawn. I have had tremendous luck with the 85% fescue/15% bluegrass blends that are commercially available, but I have not found a place that carries full hybrid seed. I would like a mix of thermal blue, dura blue, and maybe the other two hybrids. Where can I get the seed?
