Anyone who has pushed a shovel into Forsyth County ground in August knows what the grass is up against: clay that sets like fired pottery and keeps the roots shallow. Atlanta Area Aeration exists for the remedy, pulling cores across a lawn so air, water and seed can reach down where they belong. Autumn is the hour for it, once the first cool front works down the Chestatee valley and the soil finally gives. The plugs left scattered on top look like a mess for a week, then melt back in, and by the next spring that same lawn drinks a rain instead of shedding it. One job, done all the way through, rather than a little of everything.
