Most summer afternoons a thunderhead builds inland over the pine flatwoods and comes through around three, loud and brief. Southeast Lawn Co. plans the day around it, cutting Bloomingdale's centipede and St. Augustine lawns in the clear morning hours and running the edges before the first drops land. An hour later the sun is back out and the yard looks even better wet. Mowing, edging, trimming and cleanup, on the schedule a coastal Georgia growing season actually demands. Bloomingdale, Meldrim, Ellabell and the nearby stretches of Chatham and Bryan County make up the ground covered.
