Saturday morning near Lake Intervale, the neighborhood is quiet enough to hear a mower running two streets over. zamex landscaping is somewhere in that sound — cutting, trimming, edging the beds back into shape so the mulch has a clean line to sit against. Spring is the big push: bark spread dark and even, shrubs freed from the winter's mess, that first cut of the year that makes a yard look awake. Summer settles into the rhythm of the week, grass held at height, clippings swept off the drive before anyone gets home. In fall the leaves come down across the Knoll hills, and the lawns get raked open to the light one last time.
