Saturday morning around Charrette sounds like gravel under tires and a mower starting up three properties over. J&J Lawn Care LLC is part of that sound most weeks from spring into fall, running a route of yards on a steady cut so nothing ever gets ahead of anybody. Trimming goes in tight around mailbox posts, propane tanks and tree trunks; edging gives a driveway its outline back; the blower takes the rest off the concrete. The turning seasons bring the bigger jobs — winter debris out of the beds, leaves off the turf, fresh mulch laid down. Come evening the yard is finished and the weekend belongs to the people who live there.
