What do you guys use to kill crabgrass?
I planted a new tall fescue lawn by seed last fall after killing the old lawn off with round up. I winterized in the fall & applied crabgrass preventer at the begining of March and I'll be damned if I still didn't get some crab grass in an otherwise beautiful fescue lawn. This is the first time I prevented and it is obvious I will have to do it earlier next year (prolly February). My question has to do with the crab grass that has sprouted. What is a good product to use to kill growing crabgrass and not harm my fescue? Either organic or chemical is fine, what ever will get this pest out of my yard! Also should I apply a second round of preventer in May to keep the barrier strong? Thanks for the help.
