Early on a summer morning the mist sits low over the Cooper River course, sculls slide past, and the grass on the banks holds its dew until the sun clears the treeline. Hernandez Landscaping and More LLC works that hour, when a mowed stripe still shows dark and clean behind the machine. The routine is mowing on a set turn, trimming along fences, walls and posts, cutting the sidewalk line true, and sweeping the drive clear when the mower stops. Beds get opened in the spring, leaves get taken away in the fall, and hedges get held to an even face. Camden yards are often small, which means there is nowhere for a sloppy pass to hide — and no reason to make one.
