Pre Emergent Crabgrass Killer

If crabgrass has become established in your lawn, proper lawn maintenance alone may not be enough. A pre-emergent herbicide is the next line of defense. Pre-emergent herbicides work by killing the crabgrass seedlings as they germinate. The earlier that you apply the preemergent, the sooner it will lose effectiveness. The duration of effective control depends on the type of product, and how heavy of a concentration you apply. It’s always easier to control weeds before they germinate compared to spraying them after they come up and grow. Many weeds, such as crabgrass and other grassy weeds are effectively controlled with a properly timed pre-emergent herbicide.
