On September mornings the fog fills the Wallkill bottomland and the lawns above it hold the first cold dew of the year. Howell's Lawn Service, Inc. is mowing by the time it lifts, finishing the season's cuts as the grass slows and the color deepens. Cleanups follow, leaves hauled off before they mat down and smother the turf under winter. Then the plow goes on, and those same driveways get opened at whatever hour the storm decides on. Orange County will hand you all four seasons in a single week, and a property needs somebody who can meet each of them.
