re: Centipede Decline
Soil aeration is a good idea - I really need to do mine. I read that centipede doesn’t respond well to traditional dethatching techniques.

What has your fertilization schedule been like in past years - any chance you are over fertilizing? Centipede requires a good bit less fertilizer than other grasses. Over fertilization can cause decline.

You check for grubs as ronk suggested?

Man, is that what the lawn looks like? Not trying to be an arse but that is rough. That looks like spring die back. It’s not a disease. It’s higher nitrogen fert too late or too early in the year on centipede.

Yeah I checked for bugs in multiple spots and didn’t find anything. Last year I applied a total of 1 lb nitrogen.

re: Centipede Decline
It’s certain spots that look like that, most of the yard looks ok. That’s why I thought it might be insect damage like you suggested but I couldn’t find anything.

That’s correct (fertilizer)

I’m going to assume there are no dogs pissing in those dead spot areas.

I’d have to think insect or fungal disease, and again, something that occurred last fall, this winter. Centipede is not as susceptible to fungal diseases as St Augustine, but it can get them. Maybe you need to consider adding a lawn insect control and lawn fungus program.

You can contact Dr, Ron Strahan, turf speciastist, with the LSU AgCenter (rstrahan@agcenter.lsu.edu) and ask for his advice - provide him with as many details (timelines, what you are applying, how much and when, etc) and pics as practical - and not just a dead grass pic, pics of dead centipede with “healthy” centipede next to it. Send him pics of dead centipede with roots exposed in photo.
