I’ve always heard that MSMA will smoke St. Aug but I don’t have Saint Augustine. It’s done wonders on the Dallis grass in my Bermuda though.

I used this in late February on my yard.



I have St. Augustine grass. I had weeds until the weather got a little warm, then this stuff really kicked in by late March.

Then, I waited until the grass was about 75% green, around mid to late April and that's when I fertilized it, depriving any weeds of a food boost. I raked out all the thatch and used this on my lawn:



My yard really responded well to this and is now probably as lush and dark green as I've ever seen it. In the past, I always used a Weed and Feed type of treatment. Finally, went to the Agricultural Extension office of Texas A&M, and they gave me guidance. Boy, were they right. It's night or I'd snap an image and post.
