I live in the Mansfield, Tx and I have Bermuda grass. Not sure what type tho.

Ok, I will definitely dig up a spot and see. Thank you.

Mansfield and bermuda, huh. Did not see that coming.

That could be from letting the bermuda get tall and scalping it down to the stems, but that's not what it looks like. You should be mowing bermuda at the mower's lowest setting. It would look even better if you could mow it 2x per week.

Still dig looking for grubs, though. They would be near the surface.

Did you get much rain this summer, and did you continue to water during the rain? Bermuda rarely gets a disease, but it is not impossible.

Wouldn't bringing the mower to its lowest setting scalp it though?

We had a decent amount of rain. Nothing crazy tho. No, I wouldn't water my yard if we had a fair amount of rain.

Just seems odd to me that its just on that part of my lawn that I figured was the healthiest since it was always a thicker and darker green then other parts of my lawn. But I will definitely dig up a spot this weekend to check for grub worms.

Looks like mine. I was mowing twice a week end of August until we got alot of rain, and then I had to mow between raining, which turned out to be once a week. It got too tall, so I mowed it as usual, and then a couple of days later lowered the height of cut, mowed again to get back to twice a week. Scalped it! Lesson learned. It was time for a fertilizer application. I've never used Milorganite, but I did because someone told me it was good for when you scalp, and stress a lawn. I love it! It's been two weeks. My backyard with seeded bermuda looks lush & green again. But the front yard with sodded Tifway is slowly but surely coming back. After about three days after scalping it, I looked at some of the brown spots, and noticed green coming back, so I realized it was fine. All I had to do was wait it out. I wasn't sure if it would come back in time. It's been cool nights/hot days. But we had alot of rain from Harvey, and it's coming back. Oh, and by the way, before this happened my grass was very thick, lush green too. It was just getting too high, and going dormant underneath. I made notes for next year :)

Yup, too long & scalped it up causing the dreaded half moon syndrome. You lopped off the leaf & left a bare stem in those bumpy areas. You can either scalp it all down to a consistent Brown & let the green top come back over the next few weeks, or raise your deck one notch & hit those Brown spots with some fertilizer to bring them back. One thing you cannot do is leave your mower at that height, or you will get this same pattern for the rest of the year. Deck height manipulation is the hardest thing to learn with Bermuda.

When you mow bermuda low it will take on a horizontal growth character. The upright stems will flatten out and the leaves will grow up vertically. Here is a picture of bermuda mowed at 5/8-inch tall with a reel type mower.

If you mow low with a rotary type mower it cannot go this low, but lower is better. If you get the half moon scalp marks from the rotary mower, then you have a leveling issue. That can be fixed next summer.
