My entire subdivision was sodded with Centipede and many lawns look like this one. Does your neighbor have irrigation? What type of soil does his yard consist of? How big is his yard? From the photos and soil analysis, a good potassium and iron fertilizer would benefit the yard, and if cooler nights have passed your area, a low dose of nitrogen as well. That should stimulate some new plant growth from what he currently has growing, and if this works, any leftover dead material can be dethatched at a later time. I've had Centipede at my new build for a year, and despite it's reputation as an easy to manage grass type, I find it to be very fickle and particular. As such I'm still a relative Centipede novice, and I'd love to see what other Centipede owners/experts would recommend.

 

Centipede here in NC is just starting to wake up. Centipede does not like a lot attention 1-2 lbs of N a year per 1K. Too much caring for centipede can lead to decline. A good pre-e plan and a 15-0-15 fertilizer is usually recommended

 

Wise words! That's the exact fertilizer I use. I learned the hard way last summer what happens with too much N on a Centipede lawn

 

@beachlife399 yes to irrigation and very heavy Georgia clay. He put out some balanced fert this weekend because everything was so low on his soil sample so hopefully that helps bring things back for him.

 

With irrigation that should give him some positive results! It took us a full growing season for our yard to fill out. Hoping things work out for him and looking forward to updates!

 

Just a thought, Have you checked for Mole Crickets. I have heard that this year they have been the worst in a long time.
If big sections of the lawn are dead, it could be Mole crickets eating the roots of the grass.

 

Great suggestion! Mole Crickets are out in force in my area this Spring. Upon second inspection, it does look like there are small Mole Cricket mounds in OP's photos.

 

That’s a good though @Jeffersonzoysia - soapy water test would tell that correct?

 

I also use to go in depth with the passerby’s. That gets old, almost like talking to a wall. Now I tell them if they want a better looking lawn go home and lower their blade 2 notches and mow. Then raise it back up 2 notches and mow every 3rd day. If it’s not looking better in 4 weeks of doing that then come back and see me. I’ve yet to have anyone come back for more advice. Now they just wave and maybe mention it looks nice.
