I live in Houston, TX and have a St. Augustine lawn. I have checked the sprinklers and the lawn is getting good water coverage. Despite that, my lawn looks like crap. The problems are in the attached photos but summarized:
- Some areas are thick St. Augustine
- Some areas are thin and patchy with the soil showing through
- Some areas are overrun with little round leaf weeds (see photo 3 - dollarweed?) or other weeds
- Some areas have a thinner grass growing through them (rye? bermuda?)
