That would be the W&F not the lawn fertilizer, right?

Correct

My centipede lawn is in the same shape

my back yard is worse than my front yard but similar to the pics too. Bermuda is coming in so i’m thinking of just rolling with it. My buddy sprays MSM? or some shite on his bermuda and it takes out the torpedo grass pretty good. Only thing I could spray on centipede before was Hi-yield and that only suppresses it.

That’s it.

Be sure you are using surfactant (spreader/sticker) with Celsius and/or MSM to derive maximum efficacy.

I sprayed MSM Turf/Spreader Sticker Surfactant mixture on Friday. Cleggs had recommended print out with the product for mixture ratios. I used 1/2 teaspoon and 8 teaspoons per 4 gallons water in my sprayer. I had to spray 8 gallons total in my front yard. how long before I see any results? the dollarweed is the worst. I also had put out 15-0-15 centipede fertilizer Wednesday before the rain we got on Thurs.

14-21 days for results. Some weeds might have to be hit again after that.

So today is day 12 after fertilizer and day 10 after the MSM application.

I will try to remember to send pics later. The grass is greener. The dollarweed is almost bright yellow dying and the clover is drying up. the white flowers are dead brown. the yard looks like multicolored splotchy shite right now, but hoping the grass will fill in over time. I have not had to mow since the application and will be curious if the dollarweed/dying weeds will be "sucked up" and mulched.

I guess I am in wait and see mode now. maybe another MSM treatment for the survivors in another couple weeks?

no more fertilizer until Fall for centipede, correct?

What about a fall pre-emergent herbicide? I have never applied one (which is most obvious this year)

Update.... So this is what my yard looked like this morning. The MSM definitely did its job on the weeds, especially the dollar weeds. The Fertilome 15-0-15 has greened up the grass. Is there anything else I can do to speed up the filling in of the brown, or only time to grow?
thanks.

So just to be clear, we are looking dead weeds following MSM Turf spraying, and not dead centipede - correct?

If so, you just have to be patient and give the centipede time to fill in which is a slow process given centipede is a slow growing grass to begin with. A few things off the top of my head I might consider doing if it was my lawn.

1. I might get a garden rake and try to remove some of those dead weeds, might even try burning some the dead weeds in place - my thought here is exposing more bare ground for the centipede runners (stolons) to come into contact with. If any of the areas are low, I might fill and level those areas with mason sand - centipede seems to like send runners through sand in my experience (my lawn).

2. For the larger contiguous dead areas, lightly till those areas and put down some centipede sod - been a couple years since I’ve bought some but as I recall it was about $180 or so per pallet (450 sq ft).

3. Water that area regularly in the absence of rain to help promote centipede growth. Really been dry lately and not much rain in the near forecast. Of course if you sod some areas you are going to have to water those areas heavily for a few weeks anyway.

4. I might considered applying a pre-emergent herbicide now as those bare areas do have many weed seeds that will likely be germinating; however, if you do consider laying some new sod in the larger areas don’t use pre-emergent herbicide. However, it’s possible pre-emergent herbicide might suppress centipede solon growth in centipede into the bare/dead areas - maybe ronk can weigh in on this.

Regardless, it’s going to require a good bit of patience and you have to be aware that weeds are also going to try to fill in those dead areas as well.

You can re-fertilize in late July.

Have you aerated and top dressed?
