Asked April 2, 2018, 10:55 AM EDT

Hello. I was wondering when to apply crabgrass pre emigrant for my lawn this year. Weather as you know has been a little weird. Great website!! Also is granular more effective or liquid?? Thanks so much

Look at our website for crabgrass control and Tips for Application. Look for products that do not contain fertilizer. http://extension.umd.edu/hgic/crabgrass

Apply prior to crabgrass germination which begins when soil temperatures are above 55° to 60°F for 7 to10 days (during and shortly after, forsythia bloom is a rough, but not consistently reliable, guide for application timing).
Granular crabgrass products are available to the homeowner. In general liquid products are used by lawn care companies.
