I was just out at my uncle's house today trying to start fixing his lawn problem. There are a two areas of his lawn that are very bad. 1 area has been re-sodded two times but continues to die. The other part just started to look bad this year. He has had tru-green out and of coarse not happy at all with them. He also had a smaller company out. Neither company was able to fix the problem. I already know he has mole issues so I put a repellent on the lawn that I know works. I also put on a disease control product to see if that helps. I am out of ideas and have no idea what is causing this problem. My uncle is on sand but waters frequently as he has irrigation. I will be sending in a soil sample for testing this week. I know the pictures aren't great but maybe they can help, I couldn't get them any farther away do to the size limit. Any ideas of what I can do to fix this problem? I am not yet a certified applicator yet so some products might be out of my league for a couple more months. Plz, any help would be great. Thanks!!!
