The coves of Lake Arrowhead go still around dusk, and the yards above them fill with that particular Waleska evening — pine shadow, water light, somebody's grill starting up. Fusion Outdoor Living keeps the ground around that hour in shape: mowing, edging along patios and paths, trimming close to decks and posts, clearing clippings and needle litter off the hard surfaces. In these foothills a lawn is mostly the setting for time spent outdoors, so it ought to look the part before company turns into the drive. Spring comes up green and quick here; fall comes down in hardwood color. Both read better with the yard already handled.
