10 Best High Nitrogen Lawn Fertilizer 2025 in the United States

Scotts Green Max Lawn Food is a high-nitrogen lawn fertilizer designed to provide rapid greening and improvement of your lawn. With a dual-action formula that includes a 5% iron supplement, it promises deep greening in just three days, making it an excellent choice for homeowners looking for quick results. This fertilizer is suitable for use on any grass type during spring, summer, or fall.

The product's granule form allows for easy application and even distribution across your lawn, covering up to 5,000 sq. ft. per 16.67 lb. bag. Additionally, it is safe to re-enter the lawn immediately after application, and it won't stain surrounding concrete or surfaces if used as directed. Those seeking a reliable, fast-acting lawn fertilizer with added iron will likely find Scotts Green Max Lawn Food to be a valuable option.

The Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food is a dual-purpose product designed to prevent weeds like crabgrass and to feed your lawn, promoting a quick green-up post-winter. A key feature is its pre-emergent weed control, which must be applied in early spring to be effective. This product is not suitable for all grass types, specifically Dichondra and Bentgrass, which limits its applicability somewhat.

The granule form makes it easy to spread, covering a large area of 15,000 sq. ft., which is ideal for medium to large lawns. Users should be cautious of the seasonal timing for application and ensure it is applied before temperatures consistently reach the 80s. The product's high nitrogen content is beneficial for rapid greening. The bag is relatively heavy at 40.05 pounds, making handling potentially cumbersome for some users.

Since its market introduction in 2004, the product has maintained its relevance. It may not be the best choice for those with smaller lawns or those looking for an all-season solution. This fertilizer is best suited for homeowners looking to manage both weed prevention and lawn feeding in one go, particularly during the early spring season.

The Scotts Turf Builder Triple ActionI is a comprehensive lawn care product that combines weed control, crabgrass prevention, and fertilization in one formula. It offers a convenient solution for those looking to maintain a thick, green lawn while tackling common lawn issues like dandelions and crabgrass. This product is suitable for various grass types, including Kentucky Bluegrass, Bermudagrass, and Tall Fescue, which makes it versatile for different lawn environments.

The treatment covers 4,000 square feet, providing ample coverage for medium-sized lawns. The granules are easy to apply using a Scotts spreader and require watering in after 24 hours to activate the formula effectively. The recommended application is in early spring, aligning well with seasonal lawn care routines to target actively growing dandelions.

While it offers a balanced N-P-K ratio for feeding grass, it's essential to consider additional treatments if crabgrass is already present. Users looking for a straightforward, multipurpose lawn care solution will find this product beneficial, but those with severe crabgrass infestations or very specific nitrogen requirements might want to consider supplemental options.
