Hey guys, just bought a house and trying to get the lawn in order, hoping to get some help getting it sorted out. The house/lawn is 3 years old St Augustine, floratam I believe. I'm on the upper Texas gulf coast. The homeowner had been having Tru green fertilize and the neighbor was doing the mowing, very short. We had a lot of cold days over the winter with a fair amount of freezing given the area. This spring has also had a lot of cooler days even up to today in the high 50s overnight. The problem is the lawn has been very slow to green up and fill in. A lot of patchy dead areas and the grass was very loose a month ago. When I moved in a month ago I applied milorganite at approximately 2x bag rate. A week later I was looking at the lawn again and did some reading after noticing June beetles. I treated the lawn with seven insect granules. I have noticed the lawn does seem more "rooted" lately, but I can't tell if the patches are getting better or worse. I did apply some vigoro 15-5-10 about a week ago at half rate. Haven't noticed any changes one way or another. Other lawns in the neighborhood are a mix of the same, less damage, and some look great. Wondering if I'm doing things right or if I'm even treating the right problem. I know take all root rot is prevalent in southern Texas and I'm also wondering if that may be the cause. I have attached some pictures. Any help on what to check or do next would be greatly appreciated. Edited to add: The areas with the most damage seem to be the ones that get the most sun.
