This is what’s left from last year’s lawn care debacle:
Very little of what is green in this image is the type of grass you want on your lawn. I finally caved this year and hired a service to help me take care of the weed killing and fertilizing. I’m not sure I’ll have much of a yard left.

I had lawn service. Looked great and summer arrived and looks just like your grass. Pissed. Not sure what happened. Huge expense to replace. Good luck!!
Oh yes – checking into hydroseeding – cheaper than sod.
