Eliminate any unwanted crabgrass in your lawn or garden with our powerful pre-emergent crabgrass killer. This potent and highly effective product is specially designed to target menacing crabgrass before it emerges, inhibiting its growth and promoting a healthier, lush and crabgrass-free lawn.
Unlike other weed killers, our pre-emergent formulation offers a preventative solution that stops crabgrass seeds from germinating, providing a proactive approach to lawn care. This product is ideal for use in both early spring and late summer, the time when crabgrass seeds typically germinate.
Our pre-emergent crabgrass killer features a fast-acting, long-lasting formula that not only targets crabgrass but also a wide variety of other broadleaf and grassy weeds. The easy-to-apply granule form allows for perfect distribution across large areas and ensures your entire lawn is protected.
Despite its tough-on-weeds nature, this product is safe for use around a variety of grass types, including Bermuda, Bluegrass, Rye, Fescue, and more. However, it is recommended to test a small area before full application.
Respecting the environment, this product is made with eco-friendly ingredients that will not harm beneficial insects or other non-target species when used as directed.
