The old streets around Senoia are shaded by pecans and water oaks, and the houses under them have porches deep enough to sit out a July afternoon. Hearn Landscape keeps the grass beneath that canopy honest — mowing at a height the shade can carry, trimming around root flares and brick walks, edging where lawn meets path. Shade lawns are their own puzzle, thin in one place and mossy in another, and they answer to attention rather than force. Every visit ends with the walks blown clear and the clippings gone from the concrete. The house ends up looking the way its porch deserves.
