There is a kind of July noon in Red Hook when the sky goes wide and hard blue over the orchards and the Catskills stand clear across the river. Blue Sky Landscapers spends those hours on lawns — mowing, trimming, edging and shaping the ground around Dutchess County houses until a property reads as one finished piece. Heat like that grows grass fast and keeping ahead of it is half the work; the rest is detail, the clean line where lawn meets bed, the square turn at the corner. Spring finds the same crews pulling winter's litter out of the borders, and October finds them chasing leaves down a lawn. Straightforward work, under a great deal of sky.
