Fog settles into the Des Plaines bottoms most spring mornings and lifts off Libertyville about the time the first mower starts. Martin John Company takes the day from there: cutting, trimming, edging, then blowing the drive and walk down so the only thing left behind is the smell of cut grass. River-valley ground holds water, so timing matters, and you learn which yards to take early and which to save for afternoon. Spring cleanups clear the beds of everything winter left behind; autumn cleanups keep the leaf drop from turning into a mat over the turf. The craft is in the details nobody names and everybody notices.
