By the time the light slides off the lake at Murphey Candler, the fireflies are up over the grass and the heat has finally let go. Green Heaven Lawncare Services keeps Chamblee yards ready for exactly that hour — the one where somebody actually walks out barefoot and uses the lawn. Mowing, edging, trimming and cleanup, timed so the turf holds its color through the long middle of summer. A yard cut even, bordered clean and cleared of every stray clipping feels twice its size at dusk. That is the whole point of the work.
