10 Best Nitrogen Lawn Fertilizer 2025 in the United States

The Scotts Turf Builder Triple Action1 is a versatile nitrogen lawn fertilizer that also controls and prevents weeds. It stands out due to its three-in-one formula, which kills existing weeds, prevents the growth of crabgrass, and nourishes your lawn to promote thick, green grass. This product is particularly effective against common lawn weeds like dandelion, clover, and chickweed, although it won't kill existing crabgrass. It's suitable for a variety of grass types including Kentucky Bluegrass, Perennial Ryegrass, and Bermudagrass, making it a good option for diverse lawns.

Application is straightforward: spread it on a wet lawn and water it in after 24 hours. It's best used in early spring when dandelions are actively growing. A 33.94 lb. bag can cover up to 12,000 square feet, providing substantial coverage for large areas. The active ingredients, Pendimethalin, 2, 4-D, and Dicamba, help in weed control and lawn feeding.

One notable drawback is that it may not be as effective on lawns that already have crabgrass. Additionally, the product requires attention to timing for optimal results, particularly in early spring. Those with smaller lawns might find the 33.94 lb. bag to be more than they need. Scotts Turf Builder Triple Action1 is ideal for homeowners looking for a comprehensive lawn care solution that addresses weeds and fertilizes in a single application, especially if used in the right season and with the correct application method.

Scotts Turf Builder Lawn Food is a versatile fertilizer suitable for all grass types, making it a convenient option for homeowners. One of its strengths is its ability to feed and strengthen grass, helping protect against future problems and improving the lawn’s ability to absorb water and nutrients, which is crucial for maintaining a healthy lawn.

The product covers a large area of up to 15,000 sq. ft., making it cost-effective for those with sizable lawns. The granule form allows for easy application on either wet or dry lawns, providing flexibility based on your lawn’s condition at the time of application. Another advantage is its universal compatibility with all grass types, which removes the guesswork for users who may not know their specific grass type.

Scotts Turf Builder Lawn Food is a solid choice for general lawn maintenance, especially for those seeking an easy-to-use and widely applicable fertilizer.
