Dallis grass

MSM is not MSMA

What Grass type do you have?

Not OP but I have this in my yard. Centipede grass but it's pretty non-existent in that area after clearing out a truckload of weeds with the cocktail you recommended.

Looks like crabgrass but let’s see what others think. Did you use pre-emergent herbicide? If crabgrass you can spray it with sethoxydim to kill it since you have a centipede lawn.
Have you fertilized yet? If not should probably do so to start pushing grass growth.

With the large amount of dead grass areas you seem to have perhaps you should also consider applying a pre-emergent herbicide to keep summer weeds at bay while the centipede fills in - I’m a little concerned you may see a re-emergence of weeds in those “bare” areas.

Anyway, let ronk and some other weigh in on the weed ID and their recommendations.

I applied the winter weed cocktail (Fertilome weed free zone, atrazine, spreader sticker) 3/13 and then spot sprayed it on 4/1.

No fertilization yet. My neighbor told me I could use his Scott's Bonus S but ronk said it was not great for centipede and I've read similar things on other sites. Haven't figured out what fertilizer but was looking at the Ferti-lome centipede lawn fertilizer.

I feel like I need to add some soil like b-rab said before adding fertilizer but I know nothing

MSMA will kill St Aug. Celsius+Revolver+Sedgehammer is Total Tribute. It works on Dallisgrass but it too will kill St Aug. If you have a lot of spots and don't fill like dig them up I would use glyphosate concentrate because you will be able to drop a piece of sod a few days after application without having to worry about chemical damage.

The Fertilome 15-0-15 is a good fertilizer for centipede - apply 3 1/3 pounds per 1000 sq ft. Follow up with a second application in mid-June/July.

If indeed that is crabgrass those clumps by the street/driveway you could remove my hand or even spot spray with glyphosate (“Roundup”), any clumps mixed in with living centipede, again if crabgrass, can be sprayed with the sethoxydim to kill the crabgrass without harming the centipede.

Unless you had some winter kill of centipede, you had a significant amount of winter weeds you killed with the cocktail mix, just looking at the “bare areas”. Your goal should be to boost the growth of the centipede to fill in those areas as quickly as possible. Centipede grows slow so you need patience, but my centipede lawn is sending out new runners like crazy right now. I fertilized it about a week ago.

If you need to fill in low spots with soil/sand, you can can do that at anytime this summer it’s convenient for you - you need not do that before you fertilize the lawn. In fact the best time to fill low spots is when grass is actively growing and filling in areas.

Good - and going forward plan on getting on a fall (Sep/Oct) and late winter/early spring (Feb) pre-emergent herbicide program. It’s a game changer - you won’t eliminate all weeds but you’ll be amazed with the reduction of weeds you need to control beginning next spring

Looks to me like you have dalliagrass too in your yard.

To the OP: I’ve tried every method to remove dallisgrass. Everyone is right on every method mentioned. I finally got the urge to try the “glove method” with roundup this year, and I think it’s my favorite so far. It just took way too much effort and my back was aching by the time I finished.

Put on a nitrile glove. Dip hand in straight Roundup. Rub/touch your hands on ONLY the dallis leaves that way you don’t kill any desirable gras.

Either method should be equally effective - just chose the method that’s most convenient for you.
