So my new yard in TN is doing ok but I am getting a little bit of browning. We have been getting a decent bit of rain but between rains it seems to brown quicker than other yards. I'm not sure if its because the roots aren't super deep yet or if its my soil. My soil is clay heavy with about 1" of top soil. I fertilized twice this spring (.5# of N each) and overseeded. Are their any supplements I should add to the yard to help? The picture below is yesterday before mowing.
