Out on Orienta the streets bend toward the water and the lawns run down under old shade, held in by hedges that have stood longer than most of the houses. FN Landscaping LLC by Frank Novello works those properties straight through the growing season — mowing on schedule, trimming close along beds and walls, edging until every border reads as a decision. Late spring is the hardest stretch, when everything gains an inch overnight and fog rolls up off the Sound before breakfast. Shade, salt and settled soil make Mamaroneck turf its own kind of puzzle, and solving it one property at a time is the craft. The payoff is a lawn that looks composed from the sidewalk and stays that way all week.
