Easton's ground is limestone under a thin skin of soil, and the Bushkill comes down past College Hill on its way to the rivers below. Turf that does well on that ground is turf somebody paid attention to — mowing height, timing, the way a lawn answers back after a dry August. Integrated Turf Science works the lawns of the Forks with mowing, trimming and edging, plus the cleanups that bookend a growing year. A dense stand of grass with a crisp line along the walk is the visible part; the rest is knowing when to cut and when to leave it alone. Up on the hill in June, that knowledge shows from the curb.
