Some of the oaks standing in the yards out here were shading a farmhouse long before the roads were paved, and the grass beneath them grows thin and particular. Patriot Landscape Group, Inc. mows around them at midsummer, when the afternoons run to ninety and the only shade for a mile is the one you are working under. The job is weekly cutting, trimming and edging, done at whatever pace the heat allows and finished properly all the same. A country lawn is big, and the difference between mowed and finished is the last twenty minutes of trimming. Standing back at the end of the day, that difference is the entire point.
