10 Best Fall Lawn Fertilizers 2025 in the United States

The Scotts Turf Builder WinterGuard Fall Weed & Feed3 is designed to help you achieve a healthier lawn by next spring. It's a combination of weed killer and fertilizer specifically for fall use. One of its main strengths is its dual action - it not only feeds your grass but also targets over 50 types of common lawn weeds like clover and dandelion. This makes it a convenient option for those looking to tackle both tasks at once. With a coverage of up to 5,000 square feet, it's suitable for medium to large lawns.

The product is in granular form, which makes it easier to spread evenly across your lawn. However, it requires application when the lawn is wet and weeds are actively growing, ideally between 60°F and 90°F, which might limit its use depending on your local climate conditions. A notable drawback is that it is not suitable for certain grass types, including St. Augustinegrass and Bentgrass, which might limit its usage for some homeowners. Weighing 14.29 pounds, it's relatively easy to handle and apply.

It's a strong option for fall lawn care if it matches your grass type and local weather conditions, but make sure to follow the specific application guidelines for optimal results.

The Scotts Turf Builder WinterGuard Fall Weed & Feed5 is a dual-purpose product that caters to both weed control and lawn fertilization needs. It's specifically designed for fall application, aiming to ensure a healthier, greener lawn by the next spring.

One of its main strengths is its ability to kill over 50 different types of weeds, which includes common nuisances like clover and dandelion. This makes it a good fit for lawns that struggle with weed infestations. Additionally, it's versatile in terms of compatibility, being suitable for various grass types such as Bahiagrass, Bermudagrass, and Bluegrass, among others. Its coverage area of 4,000 sq. ft. is adequate for medium-sized lawns, and the product comes in granule form, which is easy to spread using a broadcast spreader.

Another advantage is that it combines a slow-release fertilizer with weed control, offering ongoing nourishment to the lawn. However, there are a few considerations to keep in mind. This product requires specific application conditions; it needs to be applied to a wet lawn with active weed growth and within a temperature range of 60°F to 90°F, which may limit its use in some climates or seasons. Also, as a synthetic option, it might not appeal to those preferring organic solutions. This product is best suited for homeowners looking to tackle both weed problems and fall fertilization in one go, provided they can meet the application requirements.

The Jonathan Green Veri-Green Starter Fertilizer is designed specifically for seeding and sodding, making it a great option for those looking to establish new grass in their lawns. The 12-18-8 N-P-K ratio indicates a high phosphorus content, which is essential for developing strong roots in new grass seedlings. This makes it particularly effective for those starting a lawn from seed or laying down sod, as it promotes deep and dense root growth.

Another advantage is the inclusion of humates, which enhance nutrient availability and help the grass absorb these nutrients more efficiently, feeding your lawn for up to 2 months. The fertilizer is easy to apply with various spreaders, and a single 45 lb bag can cover a sizable area of up to 15,000 sq. ft., making it cost-effective for larger lawns.

A consideration is that it is a granular fertilizer, so it should be applied carefully to ensure even coverage and to avoid over-fertilizing any one spot. The product's large bag size (45 pounds) can be heavy and cumbersome to handle for some users. The Jonathan Green Veri-Green Starter Fertilizer is well-suited for homeowners looking to establish a new lawn in the fall or spring, but those with smaller lawns may want to look elsewhere.
