Apply pre-emergent in early spring

Many of the best lawns are spoiled by a stubborn patch of crabgrass that sneaks back year after year. Crabgrass and annual weeds, including some broadleaf weeds, can be controlled with a pre-emergent herbicide. To be effective, pre-emergents need to be applied in early spring, before seeds germinate. Weeds seeds germinate when soil temperatures are above 50 degrees.

Do not use pre-emergents where you will be directly sowing seeds, whether that is in your vegetable gardens, reseeding a lawn, or spreading seeds for an annual flower patch.

We offer an all-natural pre-emergent product called Concern Weeds Prevention Plus. It is corn gluten-based and safe for use around children, pets and wildlife.
