South of the city the ground turns to pine and sand around Turkey Pond, and a lawn out there earns every inch of green it manages. Norman roux landscaping works that kind of soil — mowing, trimming, feeding the beds, building turf up rather than only cutting it down. Spring starts with raking the winter's grit out of the grass and ends with a yard that looks like somebody intends to keep it. Summer settles into the weekly rhythm, and October brings the leaves off oaks that hang on far too long. Concord ground is stony and particular, which is half the reason the results feel earned.
