Reddy Branch runs low and green behind the neighborhoods east of town, and by June the whole of Olney smells like cut grass and creek water. That is Better Care Landscaping Corp.'s favorite stretch of the calendar — mowing on a rhythm, trimming close around mailbox posts and oak roots, and edging the walk until the line is sharp enough to read from the street.

A lawn kept on schedule stops looking like a chore and starts looking like a decision someone made. The crew leaves the clippings blown off the drive and the gate exactly the way they found it.
