St Augustine- did I mess up

[hou-iah]

I am getting yellowing blades in my st Augustine grass. I did apply some D2 Amine a couple weeks ago but not sure if it’s that or disease or something else? Hopefully I didn’t screw myself with the D2? I read it was Saint Augustine friendly.

I always considered that normal 'thatch' in my Texas St Augustine yard.

It just nitrogen, right? I think it should fine.

The D 2 4 Amine is a weed killer...

You're not supposed to use 2,4 D weed killer on St Augustine grass. Instead, use Southern Ag Atrazine providing you don't apply it when the temps are going to exceed 90 degrees in the next few hours.
