That is fine, tall grass in the heat is necessary, but that alone doesn't replace the OM getting into the soil,,, building structure, which increase water infiltration, retention and air movement,,, provide CE sites for holding nutrients even providing habitat for earthworms to multiply in the turf...
If you can look straight down and see dirt... the sun is killing what should be living soil...
