7 Best Scotts Crabgrass Killers 2026 in the United States

The Scotts Turf Builder Weed & Feed3 is a granular weed killer and lawn fertilizer designed to cover a large area of 15,000 sq. ft. It not only kills existing weeds but also feeds the grass to thicken your lawn, making it more resistant to future weeds. This product is versatile in terms of lawn compatibility, suitable for a variety of grass types such as Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass.

However, it is important to note that it should not be used on St. Augustinegrass, Dichondra, Lippia, Carpetgrass, and Bentgrass lawns, as it can cause damage to these types of grass. To achieve the best results, it should be applied to a wet lawn when weeds are actively growing, and the temperature is consistently between 60°F and 90°F. One of the notable strengths of this product is its ability to control over 50 types of lawn weeds, including common ones like clover and dandelion.

Potential users should be cautious about weather conditions, as rain soon after application could wash away the product and reduce its effectiveness. For those with a suitable type of lawn and the right weather conditions, Scotts Turf Builder Weed & Feed3 can be a highly effective solution for both killing weeds and nourishing the grass.

The Scotts Turf Builder Triple Action1 is a versatile product designed to address multiple lawn care needs by killing weeds, preventing crabgrass, and fertilizing your grass. One notable strength is its comprehensive weed control, tackling common nuisances like dandelions, clovers, and plantains. It is also formulated to prevent crabgrass and other grassy weeds for up to four months, although it should be noted that it will not kill existing crabgrass. This makes it more suitable for preventative use rather than for treating current crabgrass problems.

Additionally, it is compatible with a variety of grass types including Kentucky Bluegrass, Bentgrass, and Zoysiagrass, making it quite versatile in terms of lawn compatibility. Its application method is straightforward; it uses granules that need to be spread on a wet lawn and watered in after 24 hours. Users should apply it in the spring when dandelions are actively growing. Each 33.94 lb. bag covers a substantial area of 12,000 sq. ft., making it efficient for larger lawns.

However, potential buyers should be aware that it is not available in certain regions such as Alaska, Hawaii, and Puerto Rico. Also, the need to apply it specifically in spring and the requirement to water it in after 24 hours could be seen as slight inconveniences depending on one’s schedule and climate conditions. Despite these minor drawbacks, this product offers a robust solution for maintaining a healthy, weed-free lawn.

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is a pre-emergent crabgrass killer that also doubles as a fertilizer, making it a convenient 2-in-1 product for lawn maintenance. With an application coverage of up to 15,000 square feet per pack (30,000 square feet total for the 2-pack), it’s suitable for medium to large lawns. The granule form makes it easy to apply, and it’s designed to withstand rain, snow, or freezing conditions, ensuring it remains effective regardless of weather changes.

It must receive some water within 2-3 days post-application for optimal results. It’s important to note that this product is not suitable for dichondra or bentgrass lawns, which might limit its usability for some users. Additionally, the mixing ratio of 30:0:4 indicates a strong emphasis on nitrogen for a fast green-up, but it may not cater to lawns needing a more balanced nutrient mix. For those with compatible grass types and looking for a combined solution to feed their lawn and prevent crabgrass, this product could be highly beneficial.
