You asked about herbicides. It is not too late. In fact, you can wait until next month! Here is the link to research-based Colorado State University Extension information about applying pre-emergent herbicides for maximum weed-killing effectiveness: http://planttalk.colostate.edu/topics/lawns/1541-pre-emergent-herbicides-crabgrass-prevention-lawns/
Basically, CSU says that the best way to get a good-looking lawn is good cultural practices. (See Extension bulletin at http://extension.colostate.edu/topic-areas/yard-garden/lawn-care-7-202/) This bulletin has very specific information, depending on the type of grass you are trying to grow.Here’s to green!
