Lake Robinson lies bright and open north of Hartsville, and in high summer the light coming off the water is enough to make you squint from the road. S&B Yard Care LLC runs town lots and lake-side places through those long weeks - mowing on rotation, trimming the sloped edges by hand, holding the bed lines sharp. Warm-season grass out here wants a consistent height more than it wants anything clever, and consistency is mostly a matter of showing up. Drives and walks are blown clear at the close of every visit. A yard that stays ready for company all summer is the entire point of the job.
