Celsius and Sulfosulfuron should kill most of your weeds.

What happened that lead to weeds taking over? What products did you apply to your lawn? The companies you listed all make products that are safe for bermuda and products that will kill/damage bermuda.

Thanks for your comment.

I live in a relatively new development. Our house was built close to a decade ago, and so we have empty lots on each side of us (though they're just starting to build in a lot right next to us). I'm guessing some of the weeds were sprung up from seeds that were churned when they built the house, or something. As I said, they sodded the front, and the back (at the time) was just sand. So I had to buy bags of dirt and Bermuda seeds to put on it.

It's out of control now, though. The sprays seem to do little to nothing. I even took one of those empty spray bottles you hook up to your water hose, put some Roundup in it, and sprayed my back yard. The weeds just laughed at me.

I've tried Scott's Weed-N-Feed, Roundup, Spectracide, and a couple of other things I don't recall. None of them have helped. In fact, the problem seems to have gotten worse.

Are you sure the "weeds" you are trying to kill is not the bermuda? Seeded bermuda looks different than sodded bermuda. And both can look very weedy depending on the length. Roundup kills everything, but bermuda at certain concentrations. Can you post pictures?

If it's really that bad new sod may be in your future. Where in Texas?

I don't have pictures, but I'm certain it's not the Bermuda I'm talking about. I know there's crabgrass, johnsongrass, and other types of weeds I can't recognize. I'll see if I can get some photos this weekend and upload. One of the types of weeds has long, thin leaves, another actually has some sort of yellowish flower on it.

Going back to the Zoysia, I've heard that might be a good solution. Unfortunately, I'd have to fight the current (and new) weeds until the Zoysia was established, which is around 45 days, based on what I've read. And I'm past the "planting" season now, which from what I understand is late Spring/Early summer. So as far as that goes, I'm out of luck until possibly next year.

I live near Dallas.

Unless you sod. You can sod anytime, even dormant bermuda can be sodded.

The best way to test your luck...try to plant another grass type. That will surely piss off the Bermuda Gods for not believing in them. You will then surely have problems trying to keep the bermuda (which you thought was gone) out of your yard.

Having grown a bermuda lawn, I would never try to grow anything on land that had bermuda. The stuff is just too tuff.

@hawksster

That's why I was reading about Zoysia. Seems like it behaves in a similar manner to Bermuda, in that it spreads underground and such. Except that it seems Zoysia is so thick in it's root system that it can choke out weeds. I don't know how much Zoysia sod costs, and I'd need a good deal of it (front & back yard). Though I did see something about "Plugs". you basically plant them a certain distance apart, and they fill in the rest.

Yes, you can start a Zoysia lawn the same way as a bermuda lawn. If weeds overtook your bermuda lawn that needs to be addressed. Highly doubtful that Zoysia would do any better at keeping weeds out. Something went awry and that need to be fixed, no matter what grass type you choose.

I'm wondering if some of it is the pH of my soil. I think I read somewhere that weeds don't like Nitrogen rich soils, so I even tried putting down Nitrogen...no dice.

Looks like I've got a good deal of work ahead of me.

Is there anything I should do heading into the Fall/Winter months to kinda prep for Spring?

You mentioned a couple of products at the top of this discussion. Celsius and Sulfosulfuron.

Where can I get those? Would I need to go to a specialty store, or could I pick them up at my local "big box" home improvement store?

First thing is to do a soil test. The recommended test cost $25 at Logan Labs in Ohio. Post your results here to get a custom analysis and recommendation.

Then decide how you want to proceed.

If you want to sod now, kill everything with glyphosate, water for 1 week, then kill what grows again with glyphosate. **If you are going to sod Zoysia, do a 3rd round of watering and glypho. If you are going to sod bermuda just the 1st 2 rounds are enough.

Another option is to kill the weeds with Celsius and Sulfo, then wait and see. Water your lawn like was new sod and see how much bermuda you can grow in the next month. It won't be much, if anything but at least give it a chance. Bermuda is very resilient, you may think it's gone, but it's not. If you have tall weeds they will simply shade out the bermuda. Getting rid of the weed competition may open the door for some of you bermuda to return. You should have a good sense of how much bermuda remains late Spring/early Summer.

No matter what path you choose you will need to start a good pre-emergent routine NOW to ward of Winter weeds and continue the pre-emergent routine for the rest of you life.

I know it's mainly been me chatting with you so far, but everything I have learned about bermudagrass has come mainly from @reeljake and @dchall. If they chime in and suggest something different, go with their suggestions.
