By late October the cottonwoods around Sheldon Lake let go all at once, and the lawns in City Park disappear under gold. Clean Air Lawn Care Chapel Hill performs the same rescue on the yards nearby: final mows, leaf collection, edges recut, beds cleared before the ground locks up. Autumn in Fort Collins is short and bright, a handful of sharp mornings between the last warm afternoon and the first hard cold. Getting a lawn cleaned off inside that window is what lets it come back green in April instead of matted. There is something deeply satisfying about handing a yard over to winter in good order.
