I had a customer that I gave an estimate to who stated that their lawn was a grass they called Emerald Blue that they had sodded. Wasn't something I have seen before. Keep in mind I am in North Ga. I had never heard of such a grass. I am 99.99% sure it is not zoysia, it was still green in the middle of winter so that points me to Fescue and KGB. I have yet to come across a KGB lawn so I am left with Fescue although this wasn't a normal looking fescue to me. It seemed to be pretty well wound unlike the tall fescue is here and other than the many weeds spread out it was in relatively good shape considering the lack of water and apps of CGM from time to time. Any thoughts as to what this "Emerald Blue" might be? I was puzzled.
