Late summer in Kirkwood ends with fireflies rising out of the grass like the yard is exhaling. Marvin Lawn Care Services LLC keeps the bungalow lawns between there and East Lake on a steady weekly rhythm, cutting, edging, running the trimmer down the fence line and clearing the drive, so evening finds the place already put right. Bermuda pushes hard through an Atlanta August, and a lawn left a week too long turns coarse; the answer is simply arriving on the day promised. Come autumn the same route becomes leaf work, the oaks giving it all up at once. The pleasure is a small yard finished completely, with nothing ragged left at the mailbox.
