Late summer near Georgica, and by six in the evening the light off the pond puts a shine on everything it touches. Geoffrey Nimmer Landscapes keeps East Hampton gardens and lawns in that light, mowing, edging, and doing the trimming and bed care that lets a designed space read the way it was drawn. Grass on the South Fork asks for attention in August, when the heat leans on it and the sand underneath gives nothing back. Weekly tending and seasonal cleanups carry a lawn composed straight through September. The result is easy to see and hard to fake: a garden that looks inevitable.
