There is a week in late May, right after a warm rain, when mid-Michigan grass grows faster than anyone can reasonably keep up with. Just-In Time Lawn Maintenance is built for exactly that week — mowing on schedule, trimming, edging and cleanup, in St. Louis and the towns around it. Arrive a few days late and a lawn stops being a lawn; arrive on the day and it never gets away from you. The pleasure is in the rhythm: same yard, same morning, clippings cleared and the edges reset before evening. Summer in Gratiot County is brief enough that it should be spent outside rather than behind a mower.
