In June the bluffs above the St. Joseph go so green it seems the color is rising out of the ground rather than falling from the light. EMERALD LAWN CARE keeps that green going lawn by lawn across Niles Township — mowing on a schedule, trimming the corners a mower cannot reach, edging the drives, tidying up when the season leaves a mess. Turf that gets cut regularly at the right height thickens and shades out its own troubles; turf scalped in August spends the rest of the year recovering. Knowing the difference is most of the craft. The rest is showing up, and leaving behind a yard that looks like somebody paid attention to it.
