Scenic Highway runs south out of Lawrenceville toward Grayson through country that greens up almost violently after a warm spring rain. Koota Kutz Landscaping Group LLC works that stretch of Gwinnett when the grass grows faster than anybody can keep up with — weekly mowing, trimming, sharp edges along drives and walks, clippings blown clear. Beds get mulched and shrubs get shaped so the plantings keep pace with the turf. Growth season here is relentless, and staying on schedule is most of the job. There is pride in pulling up to a yard on time and leaving it level and clean.
