September in the Erwin hills starts cool and ends warm, and the grass takes one last strong push before it slows down for the year. Guardian Lawncare is out through all of it — mowing the terraced yards above Route 15, running the trimmer along walls and walkways, keeping the line honest where lawn meets driveway. Late-season work is as much about setting up next spring as this week: beds cleared, leaves lifted before they mat down, turf cut clean going into frost. From the upper streets you can watch the whole valley go copper while the mower finishes its last row. Then the equipment gets put away and the yard sits neat all winter.
