Summer comes up the valley floor slowly here, the mist off Great Valley Creek burning away by mid-morning while the hills on either side hold their green a shade darker. B & R Landscaping mows into that — lawns cut on a grade, yards that fall away toward the creek bottoms, mowing lines laid straight across ground that never once agreed to be flat. They trim and they edge, working the borders along fence posts and fieldstone until the line reads crisp from the road, then clear the clippings so the grass can breathe. Fertilizing and cleanups are the unglamorous half of it; the sharp seam where lawn meets gravel drive is the half the neighbors notice. In the long light over the ridge, a freshly cut yard in this valley is worth slowing the truck for.
