Late October in Mount Vernon turns the sweetgums to rust and drops them all at once, so the last mow of the year is half cutting and half gathering. Evergreen Lawn and Hardscape LLC takes those cool mornings slow — mowing low, mulching leaves, tightening up edges that summer let get loose. Frost sits on windshields at seven and is gone by nine; the turf underneath is still green and quietly making its plans. A lawn put to bed neat in November wakes up better in March, and that is the whole argument for doing it properly. They close out the year the way they would want their own yard closed out.
