I live in Central Oklahoma (on the line between zone 6 and 7). My lawn is a mix of Fescue and Thermal Blue. I love the lawn and the bluegrass does great in the summer heat. I am building a new house and my question is, what issues would i have if any with using a strait hybrid bluegrass mix (no fescue). I can get a mix from Newsome seed that is 50% Thermal Blue, 25% Thermal Blue Blaze, and 25% Dura Blue. There are not may strait bluegrass lawns in central OK, so I dont know what to expect. I know the establishment will be longer than my fescue mix, but will i have disease problems not seen in the fescue/bluegrass mix?
