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.

It works well on all grass types and can be applied across multiple seasons—spring, summer, and fall—offering flexibility in lawn care routines. One convenient feature is that people and pets can safely enter the lawn immediately after application. If you’re looking for a fertilizer focused on quick greening and general lawn upkeep with easy application, Scotts Green Max is a solid choice, though those seeking a more balanced nutrient mix or longer-lasting feeding might need to consider other options.

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.

The product works well across various soil types but is best suited for typical lawn soils rather than highly acidic or alkaline conditions. Its 40-pound size covers a good area, making it a solid choice for homeowners seeking a long-lasting, effective fertilizer. A minor drawback is that it may be more than what very small lawns require, and since it’s granular, proper spreading tools are recommended for best results. For those wanting a fertilizer that feeds their lawn steadily with added soil benefits, this product is a strong candidate.

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.

This product is designed for use on popular grass types such as Bermudagrass, Bluegrass, Fescue, and Ryegrass, but should be avoided on certain types like St. Augustinegrass and Bentgrass. The granules apply easily with a spreader and cover up to 4,000 square feet, which is practical for medium-sized lawns. It works best when applied to a wet lawn during active weed growth and temperatures between 60°F and 90°F, but it’s important not to use it more than twice a year to avoid overfeeding.

The fertilizer’s slow-release feature helps provide steady feeding over time. This product is a reliable choice for homeowners wanting a combined solution for weed control and lawn feeding, especially for common turfgrass varieties, and is best used in warmer months when weeds are actively growing.
