crabgrass preemergence application for Spring 2016
For Garrett County/Oakland when is a good time to treat our crabgrass problem. I've researched your site but cannot find a definitive answer for this area.
In western Maryland crabgrass preemergents are generally applied in early April. Some people suggest a second application about two months after the first to assure full season control.
