September on Accabonac Harbor turns the marsh grass the color of old brass, and out toward Louse Point the light goes long and low by four o'clock. B & C Carpentry & Landscaping Inc keeps lawns through that turn of the year in East Hampton and the hamlets around it, cutting, edging, trimming back, carrying off what the season sheds. The soil here is sandy and quick to dry, so a lawn earns its green, and the reward is a yard that holds its shape right up to the frost. Fall cleanups follow, beds cut down and leaves gone before the northeast wind stacks them against the fence. Small things, done in order, all the way to the last mow.
