At Cornwall Landing the river ice goes out over one slow grinding week of March, and the village turns its mind from shovels to rakes. Benninger Landscaping works both halves of that year in Cornwall-on-Hudson — plowing, walk shoveling and salting through the cold months, then spring cleanups, mowing, trimming and edging once the ground drains. A riverside village has rules of its own: wind off the water, salt in the air, lawns that wake up in patches. Getting them even again by May is the satisfying part. Same properties, same neighbors, all the way around the calendar.
