10 Best Lawn Fertilizers 2026 in the United States

The Scotts Turf Builder Bonus S Southern Weed & FeedF2 is a combined weed killer and fertilizer designed specifically for Florida lawns. Its primary strength lies in its dual action of eliminating common weeds like dollarweed, clover, and dandelion while also nourishing the grass to promote thicker growth and prevent future weed spread. This product is particularly effective for St. Augustinegrass, Centipedegrass, Zoysiagrass, and Carpetgrass, making it a specialized choice for southern lawns. The coverage area of 5,000 sq. ft. is suitable for medium-sized lawns, and its granule form ensures easy application with a spreader, followed by mandatory watering to activate the product.

One notable limitation is that it is exclusively sold in Florida, which may be inconvenient for users outside the state. Additionally, it requires careful timing and specific application conditions (actively growing grass and weeds, immediate watering) to be effective. This fertilizer does not provide detailed N-P-K ratio information in the brief, which could be a drawback for those needing precise nutrient management. This product is a solid choice for Florida homeowners looking to manage both weeds and lawn health efficiently in one step.

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 Turf Builder Triple Action is a convenient all-in-one lawn care product combining fertilizer, weed killer, and crabgrass preventer, making it a strong choice for homeowners wanting to simplify lawn maintenance. It covers up to 4,000 square feet and is designed for a variety of common grass types, including Kentucky Bluegrass and Bermudagrass. This product’s formula controls several common lawn weeds like dandelions and clover and prevents crabgrass for about four months, although it won't remove existing crabgrass.

It uses active ingredients like Pendimethalin and Dicamba. The granule form is easy to apply with a Scotts spreader, and watering after application helps activate its benefits. It’s best applied in early spring when weeds first appear, making it a seasonal product tied to lawn growth cycles. This triple-action approach is great for general lawn improvement and weed prevention, but those with specific nutrient needs or looking for a slow-release formula might want to check their soil first or consider other options.

This product is a solid choice if you want a straightforward option that feeds grass, kills many weeds, and helps keep crabgrass away with one application.
