A chinook drops off the foothills some April afternoon and takes the last of the snow with it in a few hours — and then all of Northglenn wants everything done at once. JG Landscape Services LLC meets that rush with spring cleanup, mowing set on a rhythm, trimming and edging, and fertilizer down before the bluegrass really gets going. Dry air and thin mountain sun mean a lawn out here earns its green, so cut height and timing matter more than most people expect. There is real pride in pulling up to a yard that was matted and gray in March and leaving it, by June, thick enough to walk barefoot. Serving Northglenn, Thornton, Brighton and Commerce City.
