July haze settles on the Hudson below Idlewild and the village goes still and bright, and that is the stretch when a lawn shows exactly how well it has been watered. The Lawn Sprinkler Company keeps Cornwall-on-Hudson green through it — lawn care and mowing alongside sprinkler and irrigation service, spring start-ups, head adjustments, and shutting a system down ahead of the first hard freeze. Even coverage is a quiet art: no dry crescent beside the driveway, no puddle at the low corner. Water early, cut high, and August stops being a problem. A green lawn in a dry month is not luck.
