10 Best Selective Crabgrass Killers 2025 in the United States

The Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is a dual-action product that not only stops crabgrass before it starts but also feeds your lawn for a quick green-up after winter. With a substantial coverage area of 15,000 square feet per pack, this product is quite efficient for larger lawns. The granules are easy to apply and are designed to remain effective despite rain, snow, or freezing conditions post-application.

To achieve the best results, watering or rainfall within 2-3 days of application is recommended to activate the product. However, a notable limitation is that it’s not suitable for dichondra or bentgrass lawns, so users with these types of grass should look for alternative solutions. The 30:0:4 mixing ratio ensures that your lawn gets the necessary nutrients without promoting excessive top-growth.

This product is a good choice for homeowners looking for a convenient, all-season solution to prevent crabgrass and nourish their lawn.

Careful attention to the label instructions is important to avoid harming your grass. The product’s effectiveness and safety have been positively reviewed by many users.

The main drawback is the need for proper dilution and application equipment, which might be a bit challenging for beginners.
