7 Best Granular Crabgrass Killers 2025 in the United States

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is designed to stop crabgrass and feed your lawn simultaneously. One of its primary strengths is its dual function as both a pre-emergent weed killer and a fertilizer, which helps in achieving a lush green lawn quickly after winter. It covers a substantial area of 15,000 sq. ft., making it suitable for large lawns. The product is effective against various weeds including crabgrass, barnyard grass, and chickweed.

Application is straightforward; it should be applied in early spring before the 3rd or 4th mowing and before temperatures consistently reach the 80s. Another significant advantage is its rainfastness, meaning rain, snow, or freezing conditions post-application will not diminish its effectiveness. However, it is crucial to note that this product is not suitable for lawns with Dichondra and Bentgrass. Weighing 40.05 lb., it might be a bit cumbersome for some users to handle.

Nevertheless, its ease of application and broad coverage area make it a convenient choice for most homeowners looking to prevent crabgrass and nourish their lawn simultaneously.

Scotts Halts Crabgrass & Grassy Weed Preventer is designed to prevent weed germination and is effective for a wide range of common lawn weeds such as crabgrass, foxtail, and chickweed. The product comes in a 20.12-pound bag and covers up to 10,000 square feet, making it suitable for both small and large lawns. Its granular form makes it easy to apply using a spreader.

Application can be done in early spring or fall, and the product is rainfast, meaning rain, snow, or freezing weather post-application will not affect its performance, making it quite versatile and convenient. However, it is not suitable for all grass types, specifically Dichondra or Bentgrass, which may limit its use for some users. The product is designed for pre-emergent weed control, meaning it prevents weed seeds from germinating but will not kill existing weeds. This requires timely and consistent application.

Scotts Halts is a reliable choice for those looking to maintain a weed-free lawn, provided they follow the specific application guidelines.

The Spectracide Weed Stop for Lawns Plus Crabgrass Preventer Granules is a practical choice for homeowners looking to manage weeds and prevent crabgrass on their lawns. One of its strengths lies in its dual function - it not only stops the emergence of crabgrass and other annual grasses but also targets over 200 types of weeds without harming the lawn when used as directed. Covering up to 3,000 square feet per 10.8-pound bag, it provides a decent coverage area suitable for most medium-sized lawns.

The product is rainfast, which means it can withstand rain shortly after application without losing effectiveness, a handy feature for those in unpredictable climates. It's designed for use from spring through fall, aligning with the active growth periods of weeds, which optimizes effectiveness. Ease of application is another highlight, as it can be spread using a standard spreader, though it's important to follow the application rates on the label to ensure optimal results. The granule form makes it relatively mess-free compared to liquid options.

One should consider the need for regular application, as the control lasts up to 5 months. This could mean multiple applications throughout the growing season depending on the specific weed pressures in your lawn. Some users may find the 22.3-pound package slightly heavy to handle, especially for those with physical limitations. It’s a solid option for anyone seeking a broad-spectrum weed preventer that won't damage their lawn.
