For homeowners in Commerce, Michigan, crabgrass can be an annual nuisance, but with proper care, it can be kept under control. The best way to prevent crabgrass is to apply a pre-emergent herbicide in early spring, before the soil temperature consistently reaches 55°F. In Commerce, this typically means applying a crabgrass pre-emergent between late March and mid-May to ensure maximum effectiveness.
In addition to applying crabgrass pre-emergent, keeping your lawn healthy is the best way to prevent crabgrass from gaining a foothold in your lawn. Fertilize regularly and mow your lawn at the appropriate height (2.5 to 3.0 inches) to encourage thick, healthy grass. Taller grass helps shade the soil, preventing crabgrass seeds from germinating.
Watering deeply but less frequently will promote stronger roots and healthier grass, reducing the chance of crabgrass invading your lawn. Aerating your lawn also improves soil conditions, allowing your grass to grow strong and making it more difficult for weeds to establish themselves.
If you weren’t able to apply a crabgrass pre-emergent in the spring all is not lost. There are post-emergent crabgrass treatments that can kill, or at least stunt, crabgrass plants. Even if a post-emergent application doesn’t completely eliminate crabgrass plants, it will stop them from producing seeds. This will pay dividends in subsequent years as you will not have to continually fight a crabgrass infestation.
By following these prevention methods, homeowners in Commerce can keep their lawns healthy and free of crabgrass, ensuring a beautiful, green yard all season long.
