In late May the marsh grass along Black's Creek turns all at once, and the front yards of Merrymount follow about a week behind. That is the stretch this lawn-care outfit leans into around Quincy — mowing, edging, string trimming, and carrying off the cleanup while the ground is still soft and the light runs past supper. Salt in the air keeps coastal turf honest, so the work stays patient: cut high, keep the blade sharp, come back on schedule. The best part is the last pass of the evening, when the lines run true to the walk and the clippings are blown clean off the granite steps. A block that looks tended is a small, ordinary kind of good, and it is worth doing right.
