Front yard is normally awesome, but I forgot pre-emergent this year. This shat has taken over and my grass normally responds by now. Like a dumb arse I did weed-feed from local co-op. I’ve since tried atrazine. Am I doomed forever or can this be saved?

This looks pretty dealable withable.

Is that centipede? I’d give it a safe slow release fertilizer like Milorganite and just keep it cut following the 1/3 rule. Give it infrequent, heavy watering during droughts. Spot spray whatever weeds the grass doesn’t choke out and the heat doesn’t kill.

Standard management practices should have it looking nice by mid summer, especially proper mowing.

De-thatching and Aeration would really be beneficial as well.

Did you forget that Centipede needs water

It should respond well to the upcoming rain if you're in S LA.

Which Weed & Feed did you use? Did you put it down to early?

Thanks all. It's centipede grass with some St. Augustine mixed in there. I just used the Scotts southern weed-and-feed. It controlled some stuff but definitely not whatever that one weed is that has gotten out of control.

I've been watering some but obviously not enough. We have not had been rain in Baldwin County, AL lately either.

I have never dethatched it before and haven't had issues until now. I do have a neighbor that has aerator so can borrow / use that and see if it helps.

Don't cut off more than 1/3 of the blade of grass at one time.

Grass is 3"? Then don't cut it down to 1 or 1.5"

This stuff has quite a high nitrogen ratio, especially for Centipede, and especially if you put it down during or before green up, and especially without enough water...

Scott's is 29-0-10. Did you really dump it on there? When did you put it down?

Going forward, helps to get into a mind-set of treating lawn weed control and lawn fertilization as two separate lawn management activities - applying them them together is seldom optimal for both - that is when it’s time to control weeds is not time to feed (fertilize), and often vice-versa. Applying herbicides during the 2 to 3 week period of lawn green up from winter to spring can potentially damage a healthy lawn grass.

Aeration is good.

Applied two weeks ago before we had some thunderstorms. Doubled checked and yes it was the 29-0-10. I also bought two bags that it said would cover 10,000 sqft, and I applied at a smaller rate to stretch it across my 15,000 sqft of turf.

Thanks Craw!

Dethatching Centipede isn't fantastic. Centipede has above ground runners which would be damaged in that mechanical process. I think that you would do more harm than good.

If my calculations are right then you spread at about .67 pounds of Nitrogen for every square feet. You should aim for no more that 1 pound per 1000 per year.

Rent or hire someone to aerate. Water normally (1.5 inches per week). Don’t do anything else until it rebounds. 29% N is high for centipede Thankfully you spread it thin.
