10 Best Fall Lawn Fertilizers 2026 in the United States

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.
