Q: I have a new lawn of bahia grass and it is now full of crabgrass. Is there any products I can use to kill this off. I have been pulling by hand and reseeding but I am loosing the battle. I live in Interlachen, Florida. I bought Pennington Pensicola Bahia from Lowes, and I have been also buying in bulk argentine and Pensicola Bahia from a lumber supply company in the neighborhood.

A: No post emergent herbicide will kill crabgrass without hurting Bahia, you’ll have to rely on pre-emergent applied in spring, Feb and May.
