A finished mow in Rye leaves a lawn combed into long even bands, with the edge cut clean where grass gives way to gravel and stone. Leo's Lawn Care LLC keeps these seacoast yards — the ones that take the salt wind straight off the Atlantic, the ones set behind old stone walls and back from the marsh where the tide breathes in and out twice a day. Grass comes in thick here through a long damp summer, so the work is steady and plain: mowing, trimming, edging, and tidying the growth back into shape. There is a particular pleasure in the last pass of the afternoon, when the light runs low over Route 1A and the yard sits quiet and square. That is the whole aim — a lawn that looks tended from the road, week after week.
