A lawn route is a kind of clock. Punctual Lawn Service keeps its day and keeps it — mowing, trimming, edging and clearing the clippings on the same afternoon each week, so the grass never gets a head start. Along the greenway of the Dequindre Cut the summer runs hot and wet, and seven days is just about how long a Detroit lawn will wait before it starts to look shaggy. Coming back on time is the whole difference between maintenance and rescue. Weekly lawn service, arriving when it said it would.
