Autumn around Elko smells like pecan hulls and dry grass, the groves dropping their leaves in long rows of shadow. Four Seasons Services keeps yards in order right through that turn — mowing while the growth lasts, edging and trimming to hold the shape, clearing the leaf litter that gathers in the corners and along the foundations. Warm-season grass down here browns slowly and carries its color best when it is cut level rather than short. Homes along the roads between Elko, Bonaire and Kathleen see the same routine on every visit. A yard kept simple and kept up is a good thing to come home to.
