10 Best Fall Lawn Fertilizers 2026 in the United States

The Scotts Turf Builder Bonus S Southern Weed & Feed2 is designed specifically for Southern lawns, making it an ideal choice for those with St. Augustinegrass, Centipedegrass, Zoysiagrass, and Carpetgrass. This product stands out by not only fertilizing your lawn but also controlling a variety of common weeds like dollarweed, clover, and dandelion. It covers a substantial area of up to 8,000 square feet, which is great for larger lawns, and needs to be watered in immediately after application to be effective.

The 27.59 lbs bag is easy to handle and apply with granular form, ensuring even distribution. By feeding your grass and targeting weeds, it helps build stronger roots to withstand regional stressors typical in southern climates. However, it's critical to note that this product is not suitable for Bermudagrass and may damage it if used incorrectly. Another aspect to consider is that it is a synthetic fertilizer, which may not appeal to those preferring organic options.

Safety precautions are necessary during application, especially around pets and children. If you need a product specifically tailored for Southern grass types and are okay with synthetic formulations, this could be a solid choice for your lawn care needs.

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 Miracle-Gro Water Soluble Lawn Food and Garden Feeder Bundle is designed to make lawn care straightforward by combining watering and feeding in one step. This product is suitable for anyone looking to quickly achieve a thick, green lawn, as it can be used on all grass types. The fast-acting, water-soluble formula ensures nutrients are immediately available to plants, making it a good fit for those needing quick results (quick-release fertilizer).

The inclusion of a garden feeder that attaches to your garden hose simplifies the application process with three spray patterns and a trigger lock for ease of use. With a coverage area of up to 7,200 square feet, it should be adequate for most medium-sized lawns. However, this product is synthetic and not organic, which may be a disadvantage for those preferring eco-friendly options.

Additionally, while the bundle offers convenience, it may not provide the slow-release benefits that some fertilizers do, meaning more frequent applications may be necessary. The product format is granules, which require a hose-end sprayer for application, potentially limiting flexibility if you don't have easy access to a garden hose.
