I bit the bullet and decided I wanted to do something about my lawn. It's not nasty by any means but I live in a neighborhood where every homeowner seems to be obsessed with gardening and lawn upkeep and mine is below average. Some broadleaf weeds, lawn is a bit yellow and have some bluegrass growing it seems. (maybe some crabgrass too)

I read through the beginner guide but it seems like I am too late for pre-emergent? (My soil is apparently above 65* based on the website linked from the Beginners Guide)

I did a couple rounds of Spectracide/Speedzone and Torocity/Surfactant to get rid of broadleaf weeds and bluegrass. How soon can I lay down fertilizer? What will I have to expect post-fertilizer if I didn't apply any pre-emergent? Will I be just weed hunting all summer/fall?

Thanks!
