What grass is that in the 2nd pic?
I had to give up my Koi pond. The grey cranes were getting fat on them.
It's my "Concoction" Fescue.
Every time I over seed in the Spring/Fall I intentionally try to get a blend that's different from what I've used before...I figured that way I always have a mix that's hearty enough to get around disease. I bet there are literally 20 different types of Fescue/rye/Bluegrass and blends in my yard.
