I have been touching base with some of my customers recently and have noticed something disturbing with my grass. Some of the grass is dying. I am not talking like as in hot spots or disease either. The blades of grass look like the ends were hit by lightening and exploded like a tree trunk would. Blades are sharpened if i cant shave with them in the morning so i am not thinking that is it. Double blade damage perhaps? The dead grass is yellow in color. It is a cool season grass so it should stay green like the rest. Annual ryegrass dying off perhaps? (I am just recently learning about diff grasses so i am totally guessing here.) I know many people around here add some of it to the Kentucky bluegrass for inital growth, but some of these lawns are established. Mine included. No fertalizers or any chemicals have been added. That is all i can think of to let ya guess with. Thanks for the help guys. Acute Cut p.s. I'm guessing kirby would know something atleast. He always has in the past.
