What happened?!?
I live in West Texas. First two pics are the problem, last one is months ago. Newer home with front Bermuda sod 05/2025, back is planted Bermuda (unknown varieties). I was feeling so good about my grass and it was looking amazing. Thick, dark green. It was looking great and then starting 1.5-2 months ago it started to look like this in areas. I thought it might be watering, but it is getting plenty. August-September were particularly hot with very little rain so I watered more (could I have done too much?). The last two weeks has been much cooler with a ton of rain. I did soil testing last year and we are low in nitrogen, potassium, borderline phosphorus and low in iron. Starting in Spring I initially started with heavier nitrogen content and then went to a more all around fertilizer later on. I have sprayed on chelated iron twice. No fertilizing for two months. When I did the soil sample I did notice a grub so I laid grub killer (maybe not enough?). I do notice a bunch of ants (ant hills along the sides). I do have problems with scalping especially in the front due to uneven ground and plan to level at least the front next year, but the problem areas do not get scalped easily. Anyways Im new to the grass game and have no idea what to do. What am I missing or doing wrong?
