10 Best Grass Fertilizers 2026 in the United States

Scotts Green Max Lawn Food is a granular fertilizer designed to cover up to 10,000 sq. ft., making it suitable for medium to large lawns. Its NPK ratio is 27-0-2, providing a high amount of nitrogen to encourage green, leafy growth but very little phosphorus and potassium. This focus makes it ideal primarily for promoting lush, green grass rather than root development or flower growth. The fertilizer also contains 5% iron, which helps speed up the greening process within about three days and adds a darker green color without staining nearby hard surfaces when used as directed.

Scotts Turf Builder Weed and Feed5 combines fertilizer and weed control in one product, making it convenient for homeowners looking to both nourish their lawn and reduce common weeds like dandelions and clover. It feeds your grass to help it grow thicker and stronger, which naturally helps crowd out weeds over time.

The Andersons Professional PGF Complete 16-4-8 Fertilizer is designed for lawn grasses and offers a well-balanced nutrient mix with a 16-4-8 NPK ratio, providing a strong dose of nitrogen for green growth, moderate phosphorus for roots, and potassium for overall lawn health. Its super-fine granules ensure even spreading, helping to cover your lawn consistently. This fertilizer combines quick-release nitrogen to feed your grass immediately, along with slow-release nitrogen that continues feeding your lawn for up to 8 weeks, reducing the need for frequent applications. It also includes iron, micronutrients, and humic acid, which support lawn vigor and soil health. While it’s a granular fertilizer suited for seasonal lawn care, it is not sold in California due to regulatory reasons.
