September slows the grass down around Kennebunk Pond, and Lyman yards begin trading growth for color. Tibbetts Landscaping keeps mowing right through it, holding the height as the nights cool, running the trimmer along fence lines and edging the walks so nothing goes shaggy at the borders. When the leaves come, they go — raked, blown, and hauled off before they smother the lawn under the snow that follows. Spring brings the other half of the year: the cleanup that gets a winter-flattened yard standing up green again. Lyman's back roads run past a lot of cut grass, and keeping a place in that company is the whole point.
