10 Best Lawn Fertilizers 2025 in the United States

Scotts Turf Builder Weed & Feed3 is a versatile lawn care product designed to both fertilize your lawn and control weeds. It has a balanced approach, combining weed killer and lawn fertilizer, which is ideal for users dealing with common lawn weeds like dandelions and clover. The product is effective on various grass types such as Bahiagrass, Bermudagrass, and Bluegrass, making it suitable for a wide range of lawns.

One notable feature is its broad coverage, as a single 14.29 lb. bag can treat up to 5,000 square feet, which is impressive for medium to large lawns. It needs to be applied to a wet lawn with actively growing weeds and when temperatures are between 60°F and 90°F for best results, which might require some timing considerations from the user. The granule form simplifies the application process, as it can be spread easily using a broadcast spreader.

However, the product is not available in Florida, which could limit its availability for some users. Despite this minor drawback, Scotts Turf Builder Weed & Feed3 is a strong candidate for anyone looking to manage weeds while promoting a thicker, healthier lawn.

The Scotts Green Max Lawn Food is a dual-action fertilizer that combines nutrients with an iron supplement, designed to provide rapid greening within just 3 days. This product stands out for its inclusion of 5% iron, which enhances the greening process and is suitable for all grass types. You can apply this fertilizer during any season—spring, summer, or fall—which makes it versatile for year-round use.

Additionally, its granular form and stain-free application on concrete and driveways offer ease of use and convenience. While the quick-release nature ensures fast results, it might not offer sustained feeding over a longer period, necessitating more frequent applications. Covering up to 5,000 sq. ft. per 16.67 lb. bag, it is fairly efficient for medium to large lawns.

For those who prioritize quick greening and convenience, this product could be an excellent choice, but those needing a long-term feeding solution may want to consider other options.

Scotts Turf Builder SummerGuard Lawn Food with Insect Control is a dual-purpose product designed to nourish your lawn while simultaneously protecting it from pests. With its N-P-K ratio tailored for summer use, it strengthens grass against heat and drought, making it ideal for hot weather conditions. The included insecticide effectively targets a range of pests such as ants, fleas, and ticks, which helps maintain a healthy lawn free from damage.

This product is suitable for all grass types, adding to its versatility. It covers up to 5,000 square feet, making it a good choice for medium to large lawns. The granular form allows for easy application using a spreader on a dry lawn when insect activity is detected. Weighing 13.35 pounds, it is manageable to handle and store.

One potential drawback is that it requires careful timing of application for optimal results. Additionally, it is a seasonal product, mainly for summer use, so year-round lawn care might require additional products. For those looking for an all-in-one summer lawn care solution with pest control, this product is a solid choice. Its ease of use and comprehensive coverage make it suitable for homeowners wanting to maintain a healthy lawn through the summer months.
