Out at Moraine Hills, the bog rimming Lake Defiance turns rust and copper in October, and that color is the signal for the year to change hands. Owen's Lawn Care spends the warm months mowing, trimming and blowing the walks clean, then trades the deck for a plow blade once the ground goes hard. Both halves of the job come down to the same idea — a property that looks looked-after whether it is under grass or under snow. January means driveways, walkways and salt on the slick patch that always forms by the garage door. May means green lines running across a lawn again, and the whole circuit starting over.
