Greenburgh spreads across the ridges above the Hudson, a town made of hamlets — Hartsdale, Ardsley, Elmsford — where the streets bend with the land and the Saw Mill River threads down through the middle of it. Lawn Justice LLC works those slopes on both sides of the year: mowing, trimming and edging from April into November, then plowing the steep driveways once winter comes up the river valley. Grass grows well on this Westchester ground, so keeping a lawn even means returning on a rhythm rather than chasing it. The winter version of the same job is a drive cleared to the pavement before anyone has to leave for the train. Two seasons, one street at a time, and the yard looks looked-after either way.
