Hi SB, No disrespect intended, I have only been to Texas once, and I don’t know what your area is like. Oregon is known as being a SOGGY State, much of the Western part IS, but the High Desert of Central Oregon, if a Lawn isn’t watered, it won’t be Lush and Green much of the year. Texas is much larger than Oregon, and I have no doubt that Texas, has many Climatic regions as well.
I do know the are in which John lives well, and to have a lawn look like that there, it does take water.
Stay, Cool,Safe and Healthy
