By mid-October the nights around Lapeer start dipping under freezing and every sprinkler line in the county is on borrowed time. JLC Irrigation runs the compressor through those last mild afternoons, blowing zones dry one at a time so the frost finds nothing left to break. Come May the order reverses, with valves opened, heads checked and arcs walked and adjusted until the spray lands on lawn instead of on the road. Out around Barnes Lake and back into town no two systems were ever built the same, so each one gets read before it gets touched. Water and lawn care go together here, and timing is most of it.
