Late June in Auburn Hills has a particular hour: the sun drops behind the oaks off Squirrel Road, the heat lets go, and every lawn on the street turns a deeper green than it held at noon. That hour is what this work aims at — turf mowed at the right height, fed on schedule, and left even from curb to foundation. Oakland County ground runs sandy over glacial gravel in some blocks and heavy clay in others, so no two yards ask for quite the same thing. Fertilization, weed control, aeration and overseeding are simply the ways of answering what a given lawn is asking. The reward is grass a family crosses barefoot without ever thinking about it.
