Most July afternoons the sky west of Lilburn goes the color of slate around two o'clock, and every green thing leans in to wait for it. Deans Lawn Maintenance builds the day around that — cutting early, edging and trimming while the light holds, clearing the walks before the first fat drops land on the driveway. Bermuda grows hard in Gwinnett heat and Gwinnett rain, so a lawn keeps its rhythm or loses it fast. Pulling into a yard that got away from someone and leaving it even, cool-looking and breathing again is the best part of the trade. When the storm slides off east and the sun comes back sideways, the mowing lines show.
