Got some areas of
Dead grass in my centipede- upon some research, it looks to be in need of dethatching

Anyone familiar with this process? When how etc.

Perhaps this might help. Thatch Management - LSU AgCenter . I’ve never de-thatched, only aerated. It’s possible with a centipede lawn, that lawn aeration is what you need. Centipede with its slow growth is slow to recover from lawn damage.

Some of my healthiest centipede got smoked this winter. I would have thought keeping it longer over the winter time would have helped. But all of my thickest spots are down to just the stolons; which are completed dead with no sign of life.
Other areas of my yard are brown, with some green, I think dethatching will help in these areas.

Do you rent an aerator?

Or are the little”spike shoes” good enough ?

Yes - you rent a mechanical core aerator or hire a lawn service to do it it for you. I attached a video and some verbage in the other thread you just posted in response to your question on this. No - spike shoes are not good enough.

You sure you don’t large patch fungal disease? Are the dead-brown spots circular?

It has never really looked like that. These are spots that just never green up after winter.

Was it greening up and then got hit with another frost? This happens to the small patch of centipede in my front yard. If it's in the process of greening up and it gets hit with a frost there will be spots of it that never come back.

lol….I guess all lawn grasses have pros & cons. Take away for centipede it likes acidic soil, which is not common in many areas of south LA, minimal amount of nitrogen fertilizer and a cut height lower than St Aug & higher than Bermudagrass, and doesn’t like shade. Slow to fill in damaged areas of the lawn, but quick to send runners out on sidewalks, driveways, and landscape beds …lol.

Article on “centipede decline” - bit of a dated article but everything still relevant to the OP.

No. Every year at green up there are different locations that stay dead until mid-late summer.
