Expert Response
Your best option is a pre-emergent herbicide, to kill the crabgrass before germinating this year.
There's still time to do this in the next 1 - 2 weeks. Products with the active ingredients of dithiopyr, pendimethalin, and prodiamine are known to be effective. Always read the label before application. See the article below for more information about crabgrass control.
