By October the oaks and hickories around Flowery Branch let go all at once, and a yard can vanish under leaves over a single weekend. Happy Hand Lawn Care shows up for exactly that — leaf cleanup, a last tidy cut, walks and drives cleared down to bare surface. Mornings are cool enough to see your breath at the first stop and warm by the third. There is a plain pleasure in leaving a lawn that looks swept, with the border between grass and bed drawn again.
