Looking for some help here. I put down around 100 pallets of centipede sod 12-18 months ago. Mostly in my back yard.

I’ve been using trugreen to treat my front (mix of different grasses and weeds) and my backyard, all centipede. They been treating for about a year. As of today, the front yard is still full of weeds. And now the back yard looks rough! Looks to me like brown patch. At this point, I’ve dethatched the backyard with one of dethatchers you buy at Home Depot and pull behind your mower. I’m just trying to get the dead grass out and hopefully allow some good grass to come back through. I’m assuming my next step is to fertilize? Thoughts on that? Is now the time? If so, what do I use?

Also thoughts on TruGreen? My inclination is to can em immediately. To me, they should have noticed the brown patch starting and put down a fungicide? Maybe I’m wrong….I’d like to learn from this for sure.

FYI, the sandy spots is from me top dressing a few areas with some clean masonry sand.

For reference, this is what it looked like on Aug 7 of this past year.

RA’ed for Money Board. Jk, you have a beautiful backyard.

I have no experience with brown patch, but my intuition is saying absolutely not to fertilizing. Especially centipede.

NC STATE article on Large Patch

That is large patch. Brown patch is used for cool season lawn fungus.

And yeah that’s 100% fungus. Tru green is garbage. You need to treat it asap. At lowes or Home Depot you can get Scott’s disease ex (azoxystribin) or the bio advanced propoconizole at curative rates.
You will likely need to sod most of the affected areas. As you know centipede is painfully slow to spread. A weeds wet dream if you may.

Large patch is ALWAYS in the soil. Go ahead and work on a preventative plan to prevent future outbreaks. It got me last year in some spots. It fricking sucks.

Centipede Grass Facebook Group
This is a centipede specific group on Facebook that will provide you all the info you need to tell tru green to frick off and handle it yourself. There are some legit turf grass pros in this group. It’s a wealth of knowledge on a grass that most people don’t know jack shite about.

No problem. That’s certainly a massive amount of lawn to care for on your own. If my property was that big I’d probably invest in a damn permagreen or something similar.

I’d certainly invest in something like that. I’m just uncomfortable with knowing when and what to put down. I need to just learn it.

Let’s walk you back from the edge. Most likely it’s just large patch scars. If the the spots are getting bigger then apply any fungicide that has propiconizole or azoxystrobin. Large patch is a leaf disease only and doesn’t effect the root system. Your grass will recover.

Thanks Ronk. If it’s not active, is there anything I should apply? Fertilizer? If not now, when and what would you suggest?

Listen to ronk and Crawdude
Don't overthink Centipede
Be patient right now and see what happens when we get warmer.

You’re right. I appreciate it. I was hoping one or both would reply with an opinion.

If it’s not active then an appropriate dose of fert would help. Cultural practices are huge when preventing/recovering from disease.

I fired Trugreen and within a year had less weeds treating it myself following advice from this board.

I never saw a reduction in weeds while using Tru green.
