Pennington - Signature Series Crabgrass Preventer

Pennington Signature Series Crabgrass Preventer contains two kinds of ingredients: ingredients that will help in the prevention of weeds as well as ingredients that will kill already existing weeds. When Pennington Signature Series Crabgrass Preventer is applied before germination, it will prevent crabgrass from being able to grow and will also suppress other types of weeds. It will also control crabgrass that has already emerged and germinated.  When applied post-emergence, it will control crabgrass only but will be effective up to 4 weeks after the crabgrass has germinated. For best results, Pennington Signature Series Crabgrass Preventer should be applied to already established lawns in the spring or early fall.
