We had our "summer" lawn treatment from Spring-Green yesterday. They applied fertilizer at the rate of .7 pound of nitrogen per 1000 square feet and spot treated broad leaf weeds as necessary.
They also said "Your lawn is drought stressed, more rain will help it" - Though they suggested watering. I'm not too interested in doing that, but we'll see.
I do have to say that I am still happy we did this. Even with brown grass, it looks better overall than it has since we've lived here.
