Find out if your yard is suffering from a fungal disease or an insect infestation. It looks like Austin TX. lawns have had very little rain and this can be causing lots of yards to harbor Chinch bugs or Grub worms. Take all and brown patch have been a smaller problem this year but there has been some cases of take all patch doing serious damage to lawns in South Austin.
