killing nutsedge in the Fall
I have St Augustine grass(mixture of Sapphire and Floratam) and live in Tampa Fl. After a very wet summer I am noticing nutsedge popping up sporadically in my lawn. I have used Image (specific for nutsedge) successfully in the past and spent nearly two years trying to eradicate that blasted weed.
My question is will I hurt my lawn if I use it now since it is not growing much?
In the past after using Image my grass looks a little sick (greenish-yellow in color).
