Union Boulevard on a Monday: office parks, long turf medians, and the wide green skirts around the buildings out by the Federal Center. Jays Lawn Care & Property Maintenance LLC keeps grounds like these presentable week after week — mowing on rotation, trimming around sign bases and light poles and bollards, edging the endless run of walk and curb, clearing the litter that a windy town collects. Commercial grass gets judged from a car window at thirty miles an hour, which means the lines have to be right. Residential yards get the same pass, just at a smaller scale. Steady upkeep is its own craft: nothing dramatic, nothing slipping.
