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 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.

Jonathan Green Organic Lawn Food (10251) is a solid choice for fall lawn fertilization, particularly for those preferring organic options. It boasts a 10-0-1 N-P-K ratio, which means it offers a moderate amount of nitrogen, no phosphorus, and a small amount of potassium. This ratio is good for promoting healthy grass growth without overloading the soil with unnecessary nutrients.

As an all-organic fertilizer, it is derived from natural ingredients like feather meal, soybean meal, molasses, and wheat middlings, making it environmentally friendly and safe for use around pets and children. The slow-release formula ensures that nutrients are gradually absorbed by the grass, providing long-term nourishment and reducing the risk of lawn burn.

Its granule form makes application straightforward and manageable, especially over its large coverage area of 15,000 sq. ft. This is ideal for medium to large lawns, offering extensive reach with just one application. However, the absence of phosphorus might be a drawback for lawns that are deficient in this nutrient, as it is essential for root development. Additionally, the product's weight is remarkably low (0.01 ounces), which might be confusing, as it seems too light for a product meant to cover such a large area. Potential buyers should verify this aspect. Jonathan Green Organic Lawn Food is well-suited for those seeking an eco-friendly, slow-release fertilizer that promotes robust grass growth over large areas.
