This year I’m splitting up my pre emergent and spring fertilizer applications. I just applied this:

In a few weeks I’ll put down the fertilizer.
I don’t think the brand is as important as the emergent, Dimension, for crabgrass. I just wanted a stand alone emergent and not one combined with fertilizer. I tried that last year and got a little crabgrass later in the year.
I’m still learning so always looking for advice.
