10 Best Weed Feed 2025 in the United States

Scotts Turf Builder Southern Triple Action is designed especially for southern grass types like St. Augustine, Centipede, Zoysia, and Carpetgrass. It combines weed control, fire ant prevention, and lawn fertilizing in one product, making it a convenient all-in-one solution for homeowners dealing with common southern lawn issues. The product controls a variety of broadleaf weeds such as dollarweed, dandelion, and clover, which are typical nuisances in these regions. It also provides up to six months of fire ant prevention and helps protect against other pests like armyworms and ticks, which adds extra value beyond just weed and grass care. The granular form is easy to apply with a spreader, and one bag covers a generous 8,000 square feet, suitable for medium to large lawns. The fertilizer component is formulated to strengthen your lawn, particularly helping it handle heat and drought stress common in southern climates.

Since it is tailored for specific southern grass types, it won't be effective or safe for use on northern grasses like Kentucky bluegrass or fescue. Also, the pest control focuses mainly on fire ants and some insects but doesn’t cover all possible lawn pests. While it is a bit heavier compared to some products, this weight corresponds to its large coverage. For someone with a southern lawn looking for a combined solution to weeds, ants, and fertilizing, this product offers good value and convenience. Users with different grass types or specific pest issues might need a more specialized product.

Scotts Turf Builder Weed & Feed3 is a granule-based weed killer and fertilizer designed to treat a variety of common lawn weeds, including dandelions and clover, while promoting healthier, thicker grass growth. This product is versatile in that it can be used on multiple types of grass such as Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass.

One of its major strengths is its broad coverage area, with a 14.29 lb. bag being sufficient for up to 5,000 sq. ft., making it suitable for medium to large lawns. Additionally, it controls over 50 types of weeds, which is quite comprehensive for a product in this category. Users should apply it to a wet lawn during active weed growth periods, ideally when daytime temperatures range between 60°F and 90°F for optimal results.

A notable limitation is its restriction in Florida, so residents there will need to seek alternative solutions. Additionally, timing and application conditions are crucial, as improper application might reduce effectiveness. Despite these minor constraints, Scotts Turf Builder Weed & Feed3 is a strong candidate for homeowners looking to manage weeds while feeding their lawns effectively.

The Roundup Dual Action Weed & Grass Killer Plus is designed to kill existing weeds and unwanted grass down to the root while preventing new ones from growing for up to four months. It works on a variety of weeds and grasses, making it a good choice if you want broad weed control in hard-to-reach areas like cracks in driveways, sidewalks, patios, and gravel spots. The product comes with a Pump ‘N Go 2 Sprayer that allows you to spray continuously for 10 minutes, helping to cover the entire area effectively. It's rainproof within 30 minutes, so you don’t have to worry about rain washing it away soon after application, and you can expect to see results in as little as 6 hours. The coverage area is about 300 square feet per gallon, which is suitable for medium-sized yards or problem spots.

One important point is that you should avoid planting seeds, sod, or ornamentals for about four months after use, which might be a drawback if you want to replant quickly. The product doesn’t provide added nutrients or fertilizer benefits, so you’ll need to manage lawn feeding separately. Since it’s intended for use on hardscapes and around well-established plants, it’s best if you want to clear weeds without harming your grass or flowers.

This product is a strong option for those needing a reliable weed and grass killer with long-lasting prevention, especially for tough spots around your yard or driveway.
