I have full grown crabgrass with seed heads everywhere.
Drive XLR8 is a post-emergent herbicide only. So while it will kill existing plants, it does not prevent new seeds from germinating. We recommend using a pre-emergent such as Dimension 2EW in the spring before soil temps reach 55 degrees to prevent new crabgrass from growing next year.
