10 Best Selective Crabgrass Killers 2025 in the United States

Scotts Turf Builder Triple Action1 is an all-in-one lawn care solution that can kill a range of common weeds, prevent crabgrass for up to 4 months, and fertilize your lawn. It is suitable for various grass types including Bahiagrass, Centipedegrass, and Kentucky Bluegrass among others. The product comes in granular form and is easy to apply with a Scotts spreader to a wet lawn.

It requires a follow-up watering after 24 hours and is best applied in the spring when dandelions are actively growing. Each package covers up to 4,000 square feet, making it a good option for medium-sized lawns. A key advantage is its versatility in addressing multiple lawn care needs in one application.

On the downside, it does not kill existing crabgrass, which may be a limitation for those looking to address an already established problem. Additionally, the product is not available in some regions like Alaska and Hawaii. For those within the availability zone, this product can be a great help in maintaining a healthy and weed-free lawn.

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.

It is safe to use on a variety of common lawn grasses like Bermudagrass, Kentucky Bluegrass, Fescues, and Ryegrass, making it a good fit for many typical lawns. 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. If you're looking for a weed killer that targets crabgrass and other common weeds without damaging your lawn, this Ortho concentrate provides a reliable option with good coverage and fast results.
