By late August, Irondequoit Bay lies flat as glass in the evening, masts ticking softly at the marinas below the bluff. Cammilleri Lawn & Landscape works the neighborhoods above that water, mowing lawns that stay green well into fall thanks to the humidity the bay holds onto. Trimming and edging give a yard its outline; mulched beds keep the shape through the hot weeks when the grass would rather quit. When the season turns, leaf cleanups run right up until the maples along the bluff give up the last of them. There is a particular pleasure in a lawn cut on a still evening, when the stripes stay visible until the light finally goes.
