I have been sparying it with Roundup, then planting new seed. However, my wife is yelling at me for doing that because the brown dying grass is uglier than the green, ugly grass. Besides, it seems to be a never-ending project because as I kill off the worst of the bad grass, I get more and more particular about what "good" grass should look like.
I have 2 questions:: 1) What if I stop using Roundup and just overseed the "bad" areas like crazy with new dwarf fescue, and mow at about 2 and 1/2 inches. I am thinking the thick Fescue would eventually choke out the ugly grass -- especially if I mow a little shorter, which the Fescue would tollerate better than the ugly grass, which is taller. That way, I wouldn't have to work so hard, and my wife would yell at me less. Would it work?
2) Although my description of the ugly grass is kind of sketchy, can anyone take a stab at identifying it? Perhaps there is a selective poison for it.
