The soil around Somerville runs red — old Piedmont shale that bakes hard in August and turns to velvet after rain. Black River Maintenance, LLC. reads that ground for a living: where the mower should ride high, where a lawn needs a rake more than a blade. Late spring is the long stretch, grass growing faster than the week allows, and the route keeps up with it. Trimming along fences and foundations, cleanups when the season flips, mowing week after week. The result is a yard that looks looked-after from the street, which is all most people ever wanted.
