The Sans Bois hills stand up dark and wooded south of Stigler, and in April the valley floor between here and the Arkansas River greens a full week ahead of the ridges. Ashe & Sons Landscaping mows and keeps lawns through Haskell County, where oak-and-hickory shade means half a yard grows one way and half grows another. The cut is set for the sunnier half and the shaded part is trimmed clean rather than scalped, with edges run along drives and walks so the lines stay honest. A rainy spring in this part of the state can put four inches on a lawn between visits, which simply means showing up. Mowing done and the drive cleared, a house under those hills looks exactly the way it ought to.
