Hi all.

These pictures are of centipede grass that was sod laid down about 3 months ago. Not sure if these pictures are taken well enough, but there are certain spots in the lawn that are dying it seems. There has been a lot of rain lately so moisture is not a problem.

Could this be Thatch as the lawn clippings are not collected up? If so, what can be done to remedy this? If not thatch, any other ideas?

Thanks a lot

Was Bolster mixed in with the soil prior to installation? I'v had great success with this product. If not, what fertilizer was used?

Bolster was not mixed into the soil.

The fertilizer used was a 32-0-4 a few months after it was laid down.

32-0-4 is certainly the wrong fertilizer for new sod. I strongly suggest to contact your county extention agent and find out which Professional landscape company he recommends you use, Fire the one you have because they don't have a clue if the are using 32-0-4 on new sod.

I hope this was a homeowner mistake. Things like that happen but a landscaper certainly should know better.

So do you think the fertilizer is the culprit? If so, just time to heal? Any chance thatch is involved as well?

Looks like fert burn to me. I'd leave it alone and see what happens. It may come back strong but it will probably be next spring.

spittlebugs?

There are quite a bit of spittlebugs actually, they can do that kind of damage?

That is the look of grass burned by too much nitrogen from the wrong source, not enough potassium and not enough micronutrients. I am also guessing that this centipede is on alkaline soil as well. Centipede grass has very specific requirements unique to it. What you may use on other turf with little harm, can severely damage centipede. 32-0-4 is no where near an analysis that I would consider applying to any turf, much less centipede.

One thing to note though, can nitrogen burn not show up for up to a month? The fertilizer was put on about a month before the burns were showing up.

At first you could see that the fertilizer made the grass a lot greener.

As greendoctor said: "There's a whole world of differences between centipede and other turf," and as Ric mention that fertilize is not even close. Centipede will not do well on that much Nitrogen. For starters check your pH--I'll bet that it is way over 7.2. Has got to be down around 6. Then PM me (IF WANT TO) with what you have done, if you have irrigation, when you put that fertilize down, did you keep it moist (Not soggy) for two weeks after laying sod, and exactly when you put the sod in and if you'd used any pre-em or herbicides. Centipede would do best on a 1:2 ratio of Nitrogen to Potassium Nitrate. If you used any Muriate of Potash (chlorine based) potassium, but you didn't use that much thank goodness; then you will see a steady decline and but that generally happens a bit later. How did the sod look? Sometimes sod is left too long on the pallet and it suffers heat damage especially now.
Lots and lots of variables to consider.

Like GD & Ral said, centipede is a different animal than other warm season grasses. Ral will fill you in.
BTW clippings are not thatch and clippings are beneficial if other factors are correct.
