Late May in the coves above Dahlonega belongs to the mountain laurel — pale bloom back in the shade, moss creeping over every north-facing stone. Art Of Stone Gardening tends yards in that same register: mowing and trimming, shaping shrubs, edging planting beds so the line between lawn and garden stays deliberate. Shade is the local puzzle, with tulip poplars and oaks closing in overhead and the turf thinning beneath them, so cutting height and frequency get adjusted rather than forced. The reward is a small, composed piece of ground that plainly had someone thinking about it. In these hills that is a quiet sort of beauty, and it is worth keeping up.
