The San Pasqual Valley is one of San Diego County's working landscapes — citrus groves and farm fields held in a bowl of dry hills — and on a spring morning the smell of orange blossom carries for miles. Canterbury Landscaping keeps lawns in and around that valley: mowing, feeding, trimming, coaxing green from ground that spends most of the year in sunshine. A tended lawn at the edge of grove country has its own quiet dignity. The work ranges from the valley floor up into Escondido and out toward Ramona. Each visit ends the same way, with straight lines in the grass and the hills standing gold beyond them.
