10 Best Weed And Grass Killers 2025 in the United States

The Scotts Turf Builder Weed & Feed3 is a dual-action product combining weed control and lawn fertilization, making it ideal for those looking to maintain a healthy and weed-free lawn. It effectively tackles over 50 types of weeds such as dandelion and clover, providing both immediate and preventative care by thickening your lawn to crowd out future weeds. This product is suitable for a variety of grass types, including Bermudagrass and Fescue, covering up to 5,000 sq. ft., which makes it a good option for medium to large lawns.

The active ingredients, 2,4-D and Mecoprop, are common in weed control products, known for their effectiveness, though users concerned with chemical usage should take note of potential safety and environmental impacts. The granular form makes it straightforward to apply, though optimum results require specific conditions: application to a wet lawn and temperatures between 60°F and 90°F.

An advantage is its dual purpose, saving time with combined weed control and fertilization, boasting a 28-0-3 N-P-K ratio that supports lawn health. However, one drawback is its unavailability in Florida, which may limit access for some users. Additionally, users must be cautious of run-off concerns, especially near water bodies, given its chemical nature.

In conclusion, Scotts Turf Builder Weed & Feed3 is a practical solution for homeowners seeking to manage weeds while promoting lawn growth, though it demands careful application and consideration of environmental precautions.

The Roundup Weed & Grass Killer₄ with Sure Shot Wand is a versatile weed and grass killer suitable for use in and around flower beds, trees, and driveways. This product excels at killing tough weeds and grasses down to the root, making it effective against a wide range of common weeds such as dandelions, crabgrass, and poison ivy. One of its standout features is its rainfastness, becoming rainproof just 30 minutes after application, and visible results can be seen in a matter of hours. This makes it a convenient option for those looking for quick and effective weed control.

Additionally, the product allows for planting 1 to 30 days post-application, offering some flexibility for gardeners planning new plantings. The included Sure Shot Wand extends 2 feet and has a shield to help target the spray precisely, reducing the risk of damaging nearby desirable plants. However, one drawback is that it is a chemical-based product, which may raise concerns regarding safety and environmental impact. Users should handle it with care and follow all safety guidelines. The product covers up to 300 square feet per gallon, which should be sufficient for small to medium-sized areas.

This product is well-suited for homeowners looking for a reliable and efficient weed killer for various outdoor areas, but it may not be the best choice for those seeking organic or environmentally friendly options.

Scotts Liquid Turf Builder with Plus 2 Weed Control is a multipurpose product designed to both eliminate weeds and fertilize your lawn. The liquid form makes it easy to apply: just attach it to your garden hose and spray. Its active ingredient is nitrogen, which helps in providing a quick boost to your lawn while controlling broadleaf weeds such as dandelion, clover, and poison ivy.

This makes it suitable for various types of grasses including Bluegrass, Fescue, and Ryegrass, among others. One 32 fl. oz. container covers up to 6,000 sq. ft. for warm-season lawns and 4,000 sq. ft. for cool-season lawns, so it offers good coverage. On the downside, its effectiveness is contingent on the weeds being actively growing at the time of application. This means it might not be as effective in controlling dormant weeds.

Additionally, while it is convenient, the liquid spray may pose some safety concerns if not applied properly, and care should be taken to avoid run-off into environmentally sensitive areas. This product is best suited for homeowners looking to improve their lawn’s appearance quickly by tackling common broadleaf weeds while also fertilizing their grass.
