When to Apply Crabgrass Preventer

Crabgrass preventer or preemergent should be applied in late winter or early spring before the crabgrass emerges. There use to be easy postemergent solutions that killed crabgrass pretty easily, but due to some EPA guidelines, these are no longer available for residential use. Therefore the best chemical method of getting rid of crabgrass is using a preventer before it emerges.

So, what does crabgrass look like? It has coarse leaves and thick stems that form a circular base at the ground. Crabgrass is one of the hardest weeds to get rid of and presents most lawn owners with a great challenge. Sometimes it requires some serious elbow grease to get rid of it by simply pulling each plant out of the ground and throwing it away. Let’s hope it doesn’t come to that for you!
