Chem Lawn is a commercial service that will bring a truck loaded with liquid chemicals to your home and apply it to your lawn (and garden if contracted for it) so that you don't even have to do it yourself.
My next-door neighbor has had a stalled lawsuit in process for about two years now on his claim that the truck they said was full of fertilizer actually contained "RoundUp."
I could testify that all his pretty grass (and everything else) died quite suddenly; but he hasn't asked for witnesses. They'd probably discount my testimony since, being the only one in the neigborhood who doesn't fertilize weekly and run automatic lawn sprinklers to wash it into the river every other day, my lawn "looks like crap" (a quote from one of my neighbors).
