The first honestly cool morning reaches Thomas County some time in October — dew heavy on the Bermuda, air gone clear, the whole day easier to work in. Edwards Lawncare Services LLC likes that stretch: mowing while the grass slows, edging and trimming, hedges cut back, and the leaves and pine litter pulled off the turf. Before it, the summer has run hard since February green-up, week after week of growth that never asks permission. After it comes the tan season, when a yard still wants its lines kept and its beds neat. Steady hands, all the way around the year.
