Late August in Methuen: the grass has come back from its July sulk, evenings arrive early, and mowers run until the light goes off the ballfields. Hc Landscaping inc. keeps lawns on that rhythm — cut at the height the month asks for, trimmed clean around posts, hydrants and hedges, edges defined so a yard has an outline again. Fall brings the long labor of leaves, dragged off the turf until green shows through; spring brings the reverse, opening a lawn back up after months packed under snow. Yards here sit small and close together, which means every line shows and every missed corner shows too. That is exactly the appeal of doing it properly.
