re: What is going on with my grass??

Thanks craw. It has been sprayed this fall with Preemergent, insecticide. Not sure about fungicide. (I hire fall and winter preemergent work out). The lawn is not watered a great deal and we don’t receive a great deal of rain so I wouldn’t think it would be a fungus. The lawn is also cut shorter at 2”.
The dying of the centipede is not a huge concern bc I’m in the process of plugging out the front yard with celebration Bermuda. Given that, no trees in the front but this is a large area. Front is probably 3/4 acre. About 75% of that 3/4 is still centipede. Looks like I’ll be plugging a lot this coming spring.

Thank you for your reply as this has been very annoying and can’t figure it out.
