10 Best Lawn Fertilizer For Spring 2025 in the United States

Scotts Green Max Lawn Food is a dual-action fertilizer that includes an iron supplement, designed to improve lawn greenness within three days. The product is designed for use in multiple seasons, including spring, summer, and fall, and is suitable for all grass types. This makes it versatile for different lawn care needs throughout the year. The inclusion of 5% iron is a significant feature, enhancing the greening process.

One notable advantage is that it does not stain surfaces like concrete or driveways, provided it is used as directed, which helps in maintaining the cleanliness of the surrounding area. Additionally, it covers up to 5,000 square feet, making it suitable for medium to large lawns. Users can re-enter the lawn immediately after application, making it highly convenient for busy homeowners. However, there are a few aspects to consider. The product uses synthetic ingredients, which might not appeal to those seeking organic options.

Furthermore, it does not provide weed control, focusing solely on fertilization and greening, which might require additional products for comprehensive lawn care. The granule form of the product ensures even distribution, but it requires a spreader for application, which could be an extra cost for some users.

The Scotts Turf Builder 4 Bag Bundle is designed for small lawns and includes a variety of season-specific fertilizers and treatments. This bundle is particularly comprehensive, providing a year-round solution for lawn care. The N-P-K ratio and specific nutrient breakdown for each product are not detailed, but the focus on crabgrass prevention, weed control, insect protection, and seasonal feeding suggests a well-rounded nutrient approach.

The inclusion of both slow-release and quick-release elements helps ensure immediate results and sustained lawn health over time. However, for those seeking an organic option, it's important to note that these products are synthetic. The Weed & Feed5, equipped with WeedGrip technology, is particularly effective against common weeds like dandelions and clover, which is a significant advantage for maintaining a clean lawn.

The granular form makes for straightforward application, although users must follow the specific instructions on each bag for best results. One potential drawback is the separate shipping of products, which might result in staggered arrivals. This product is best suited for homeowners with medium coverage lawns seeking a convenient, all-in-one solution for year-round lawn care.

The Scotts Turf Builder Bonus S Southern Weed & Feed2 is specifically designed for Southern lawns and covers an area of 4,000 sq. ft. This product is a combination of weed killer and lawn fertilizer, targeting a variety of common Southern weeds like dollarweed, clover, and dandelion while feeding the grass to promote thicker, healthier growth. The fertilizer also helps grass develop strong, deep roots to better withstand Southern climate stressors.

It is suitable for use on St. Augustinegrass, Centipedegrass, Zoysiagrass, and Carpetgrass, making it versatile for different types of Southern lawns. The granular form ensures ease of application, but it requires watering in immediately after application for the best results. This product is not organic, which might be a consideration for those looking for natural options.

It is essential to apply it to a dry lawn and ensure proper watering, as not doing so may limit its effectiveness. This product is best suited for homeowners with specific types of Southern lawns who need both weed control and fertilization.
