10 Best Lawn Weed Control And Fertilizer Products 2025 in the United States

Scotts Turf Builder Weed & Feed3 is a combined weed control and fertilizer product that is designed to both kill existing weeds and promote a thicker, healthier lawn. One of its main strengths is its ability to control over 50 types of lawn weeds, including common nuisances such as clover and dandelion, making it very effective for comprehensive weed management. The product works by applying the granules to a wet lawn, which allows the active ingredients like 2,4-D and Mecoprop to effectively target weeds while the fertilizer components nourish the grass.

This makes it versatile and suitable for various grass types including Bermudagrass, Bluegrass, and Fescue, among others. The coverage area of 5,000 sq. ft. ensures that a single 14.29 lb. bag can treat a sizable lawn, which adds to its convenience and value. However, potential users should note that the product is not available in Florida, which could limit its accessibility for some. Additionally, as with any chemical-based lawn care product, caution is advised to minimize any possible negative impact on the environment and to ensure safety during application.

The requirement to apply it during specific temperatures (between 60°F and 90°F) can also be a bit restrictive, as it narrows down the optimal usage period. Despite these considerations, Scotts Turf Builder Weed & Feed3 proves to be a robust solution for those looking to efficiently manage lawn weeds while simultaneously fertilizing their grass.

The Scotts Halts Crabgrass & Grassy Weed Preventer is a pre-emergent weed killer designed to stop weed seeds from germinating, targeting specific weeds like crabgrass, foxtail, spurge, and others in the early spring, as well as moss and different weeds in the fall. It is suitable for use on most grass types, except Dichondra and Bentgrass. One of its strengths is its broad application window; it can be applied in early spring or fall and is effective regardless of subsequent rain, snow, or freezing temperatures.

Additionally, the product covers a large area of 10,000 square feet, making it a cost-effective option for larger lawns. However, it does not offer fertilizing benefits, focusing solely on weed prevention. This could be a drawback for users looking for a combined weed and feed product. Its granular form makes it easy to apply using a spreader, but users should ensure uniform coverage to avoid missed spots.

This product is ideal for homeowners who need a reliable, season-long weed prevention solution for sizable lawns.

The Spectracide Weed And Feed 20-0-0 is a dual-action formula designed to tackle broadleaf weeds while simultaneously nourishing your lawn. Its strong point lies in its ability to both kill common pesky weeds like dandelion and clover and feed the lawn with a 20% nitrogen formulation that promotes healthy grass growth. This makes it an ideal choice for those looking to maintain a lush, green lawn while dealing with common weed issues.

Equipped with a QuickFlip hose-end sprayer, the application process is straightforward and convenient. You simply attach it to your garden hose, flip the switch, and start spraying, making it user-friendly even for beginners. Each 32-ounce bottle can cover up to 7,500 square feet, which is quite ample for medium to large lawns, and the six-pack offer extends this reach significantly.

A potential drawback is the environmental impact and safety concerns. While it effectively controls weeds, users should be cautious about its chemical composition, especially in environmentally sensitive areas or around pets and children. For eco-conscious gardeners, this might not be the first choice due to potential chemical runoff. Timing and seasonal application are also critical. It is most effective when used during the growing season, usually spring and early summer, when weeds are actively growing and the lawn can benefit from the added nutrients.

This product is best suited for homeowners who prioritize convenience and effectiveness in lawn maintenance and are dealing with a variety of broadleaf weeds. It's not the best option for those looking for organic or eco-friendly solutions due to its chemical-based formula.
