10 Best Fertilizer For Green Grass 2026 in the United States

Scotts Green Max Lawn Food is designed to help you quickly achieve a greener, healthier lawn with its 2-in-1 formula that combines fertilizer and an iron supplement. The N-P-K ratio is 27-0-2, featuring a high nitrogen content to promote lush green growth but very low phosphorus and potassium, which suits lawns that mainly need nitrogen for greening. The inclusion of 5% iron helps deepen the green color within just a few days. This product is a granular fertilizer that can be applied in spring, summer, or fall, making it versatile for various growing seasons.

It works well on all grass types and is safe to use around pets and people, who can re-enter the lawn immediately after application. One bag covers up to 10,000 sq. ft., suitable for medium to large lawns. It’s also designed not to stain concrete or driveways if used as directed. The nutrients are likely to feed the lawn quickly, which may require more frequent applications compared to slow-release fertilizers. The low phosphorus and potassium content might not support root development or stress tolerance as well as a more balanced fertilizer.

This product is a solid choice if you want fast greening and easy use, especially in nitrogen-loving grass types, though it may not cover all nutritional needs for soil improvement or long-term feeding.

It is suitable for use in both spring and fall when temperatures are between 60°F and 80°F, ensuring flexibility in planting periods. The product is intended for outdoor use, specifically in areas with both sun and shade exposure, which adds to its versatility. However, it is important to note that the product's availability may be limited in certain states.

The 16-pound bag size is manageable for most users, and its application method is straightforward, primarily requiring watering post-application.
