On an April morning near Harding School, the sound of a mower starting up is as much a part of Kenilworth as the crossing guard's whistle. Q&S Landscape Contracting is out in that first flush of growth, cutting lawns that have finally dried enough to take a blade and clearing the last of what winter left in the corners. Trimming and edging give a yard its outline, and the weekly cut keeps it honest from there through October. Spring cleanups make the difference between a lawn that starts the season and one that spends it catching up. It's lawn care for a borough where the yards are small, close together, and all in plain view.
