Out toward Sand Brook and Reaville the roads narrow and the lawns run right up against old stone walls and goldenrod. Sarah's Landscaping keeps those yards mown and trimmed through the long green stretch of a Hunterdon summer, with edging, mulch and seasonal cleanups besides. Country properties carry more perimeter than anyone expects — fence lines, ditch banks, the strip along the road that everybody forgets. Handling those edges is what separates a mowed lawn from a finished one. Late August, light going amber and the trimming done, is the best moment in the whole trade.
