Along Rockland's older streets, where clapboard houses sit close to the road and low stone walls trace out the yards of a former shoe-and-mill town, the grass comes in thick behind picket gates and weathered fence. Josch Landscape tends these South Shore dooryards the way you'd care for something you meant to keep — the mower's clean parallel lines drawn across a lawn, the border cut sharp against the walkway, the clippings carried off before the big maples throw down their shade. In the first warm weeks the winter's scatter is raked from the beds and the ground is opened up again; by autumn the leaves are gathered before they mat and smother the turf. It is patient, unshowy work, and the reward is plain to anyone passing: a lawn that reads as looked-after from the sidewalk, holding its green through the long, humid pull of a coastal Massachusetts summer.
