Got a questiong for you experts in this field. I have several clients (including my yard) that is turning brown and dying in large areas, looks like it was sprayed with roundup. One lady called tonight and complained about hers. We have had weeks of 100 plus degree weather and high humidity with heavy rains at night. What is causing this and what is the cure? Is it a fungus, insects or heat stressed? The lady that called has been watering hers also during the day when its hot.
