Stand on the green in June, steeple white against the trees, and Durham looks like a town that has always cut its grass on a Saturday. Morin Landscaping keeps that going all summer — mowing, trimming, edging, mulch, and cleanups when the season opens and again when it winds down — then turns to the plow once Allyn Brook goes to ice. Two trades, one habit of mind: leave the ground better arranged than you found it. A lawn cut in even stripes and a driveway opened corner to corner scratch precisely the same itch. Out this way the yards run big and the borders run wild, which makes a finished edge worth the extra pass.
