Fog rolls off the Sound near Reeves Beach and sits over the bluff-top yards until the sun burns through around nine. Salazar Landscaping is usually well into the day by then — mowing, edging, trimming hedges, weeding and mulching beds, carrying clippings off the property. Salt air and sandy ground make for lawns that need attention rather than luck. There is something satisfying about the moment the mist lifts and a finished yard is simply sitting there, trim and even, with the borders holding their shape. Riverhead and the north-shore hamlets are on the schedule.
