That's wierd! (Sorry...) Kentucky Bluegrass - which we have here being Tennessee - is a "cool to warm" weather grass that won't stand the heat of summer. It doesn't do well in high heat at all - which is why in my region - it's generally used to overseed with and to keep the lawn looking good inbetween seasons (when it's not too hot and not too cold). General 31 Fescue is an grass used to stand up to high heat and drought - which is what's sold and used in this area for dead on summer because it's SO DARN HOT! In the winter - we'll overseed with a strictly cool weather grass only and that takes care of that.
What's the temperature like where you live? That should be the determination for what grass is planted - because it will really cut down on the maintenance and help the appearance overall. We don't have to water, and only weed-n-feed twice a year... once in the spring and once in the fall - that's it. But again - this is Tennessee and the climate is more indicative for grasses than some other regions.
I don't know if that helps you at all - but I really would look into grasses designed for your specific area and climate and see if you could try doing a blend of Ky Blue with another grass that might be a little less hard to grow for your place!
