Move a mile or two inland from Belmar and the shore grid loosens into the open ground of Wall Township, where the wind has room and the grass starts early. Wall Lawn Mower Service, LLC works both sides of that line — mowing on a weekly turn, trimming close, edging the walks from the first cut of spring to the last one of autumn. Cleanups get a property out from under winter in March and put it back to bed in November. A lawn near this coast takes salt, sun and sudden rain, and answering all three is mostly a matter of showing up on the right day with a sharp blade. The result is plain and satisfying: even color, a straight edge, a yard that looks looked-after.
