Full Answer

Most crabgrass preventers are effective for about 30 days. They interrupt the germination process of crabgrass. They contain pre-emergent herbicides and fertilizers. In addition to killing crabgrass, they strengthen the turf grass.

Crabgrass cannot be dealt with in a single season. A combination of pre-emergent and post-emergent herbicides minimizes the amount of crabgrass annually. Pre-emergent herbicides stop the germination process. Post-emergent herbicides deal with the remaining crabgrass and stop it from reaching the seeding phase.
