August in Allendale is a test of patience: the sand beneath the turf lets water straight through, and a lawn can go straw-colored after a week of west wind and hard sun. Grand Valley Lawn Sprinkling Llc keeps its lawn care tuned to that — mowing high while the heat sits in, trimming close along the walks, reading each yard for the dry corners the sun finds first. Then the September rain arrives off the lake and everything comes back green almost overnight. Mown, trimmed, edged, cleaned up, week after week from the first flush of May to the last cool cut of October. It is ordinary work, done attentively, and it shows from the street.
