10 Best Cheap Lawn Fertilizer 2025 in the United States

The Scotts Turf Builder Weed & Feed3 is a combination of weed killer and lawn fertilizer designed to control a range of common lawn weeds like dandelions and clover while nourishing the grass. This product is suitable for various grass types including Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass. One of its key strengths is its coverage; a 14.29 lb. bag can cover up to 5,000 sq. ft., making it a cost-effective option for medium to large lawns.

This product works by killing over 50 different types of weeds and feeding the lawn to make it thicker and healthier, thus preventing future weeds from taking root. The product is synthetic, so it acts quickly but might not be the best choice for those seeking an organic option. Users should apply it to a wet lawn when the weeds are actively growing and the daytime temperatures are between 60°F and 90°F for optimal results.

However, it is not available in Florida, which limits its accessibility for some users. Additionally, the need for precise weather conditions for application could be seen as a drawback. Despite this, its dual action as both a weed controller and a fertilizer, combined with its extensive coverage and ease of application in granule form, make it a strong contender for those seeking an affordable solution for lawn care.

Scotts Liquid Turf Builder with Plus 2 Weed Control is a practical option for those looking to fertilize their lawn while simultaneously tackling a variety of broadleaf weeds. One of its main strengths is its dual functionality; it not only provides essential nitrogen to promote grass growth but also effectively targets common weeds like dandelions, clover, and poison ivy. This makes it a convenient choice for homeowners wanting a comprehensive lawn care solution.

The product is designed for easy application with a ready-to-spray form, which is suitable for various types of grasses including Bluegrass, Fescue, and Bermudagrass. Additionally, the 32 fl. oz. container covers a respectable area of 6,000 sq. ft. for warm season lawns and 4,000 sq. ft. for cool season lawns, offering good value for its size.

However, there are some limitations. As a synthetic fertilizer, it may not appeal to those specifically seeking organic options. The product also requires weeds to be actively growing for effective application, which might limit its use during certain times of the year. Additionally, while the liquid form is convenient, it might not provide the long-term benefits that granular fertilizers offer. Scotts Liquid Turf Builder with Plus 2 Weed Control is a solid choice for homeowners needing a quick, effective boost in lawn care and weed control, provided they are comfortable with synthetic products and seasonal application conditions.

Scotts Turf Builder Lawn Food is a versatile lawn fertilizer that caters to all grass types and covers a substantial area of 15,000 sq. ft. This makes it a good choice for large lawns. Weighing 37.50 lbs, it is designed to be easy to apply on both wet and dry lawns, providing flexibility for users.

One notable strength is its capability to feed and strengthen grass, promoting deep root growth and improving the lawn's ability to absorb water and nutrients. This can result in a healthier lawn that is more resilient to future problems.

Despite being a synthetic product, its broad coverage and ease of use make it a strong contender for those in need of a reliable and effective lawn fertilizer at an affordable price.
