10 Best Fertilizer Centipede Grass 2025 in the United States

The Fertilome Centipede Lawn Fertilizer is designed specifically for centipede grass, with an N-P-K ratio of 15-0-15, providing a good balance of nitrogen and potassium but no phosphorus. This composition is beneficial since centipede grass often grows well in soils already containing sufficient phosphorus. It uses slow-release nitrogen, which helps deliver nutrients gradually, reducing the chance of burning your lawn and supporting steady growth.

The 16-pound bag covers up to 5,000 square feet, making it suitable for medium-sized yards. The fertilizer suggests application twice a year—in early spring and early fall—at a rate of 4 pounds per 1,000 square feet, aligning well with typical centipede grass care routines. It does not include added micronutrients like iron or magnesium, and it does not adjust soil pH, so checking your soil’s pH before use is important, as centipede grass prefers slightly acidic soil (around pH 5.0 to 6.0).

This fertilizer is ideal for homeowners with centipede grass who want a straightforward, slow-release formula focusing on nitrogen and potassium without extra micronutrients. If your soil lacks phosphorus or you desire faster greening effects, you might need to consider supplements or alternative products.

The Safer Brand 9335SR Lawn Restore Natural Fertilizer is designed to improve lawn health with a 9-0-2 NPK ratio, offering a good amount of nitrogen for greening but lacks phosphorus and has a small amount of potassium. This ratio suits lawns like centipede grass, which generally don’t require much phosphorus. The fertilizer is slow-release, helping feed your lawn gradually and reducing the risk of burning, which is great for sensitive grasses.

It’s made from natural ingredients that promote soil health and are safe for children and pets right after application. Users can expect to see greener grass within a few days, and the formula also helps the lawn resist heat and drought stress. It covers up to 5,000 square feet, making it a good choice for medium to large lawns. Slow-release fertilizers typically require fewer applications, making this product convenient to use.

This product is a solid option for someone looking for an easy-to-use, pet-safe fertilizer that focuses on nitrogen feeding without risking burns, especially for centipede grass which prefers lower phosphorus and careful nutrient management.

Milorganite Lawn and Garden Nitrogen Fertilizer 6-4-0 offers a tailored solution for lawns, including centipede grass, and edible gardens. The N-P-K ratio of 6-4-0 indicates a focus on nitrogen, which is essential for green and lush grass, making it suitable for centipede grass that thrives on nitrogen-rich nutrients. Its slow-release formula is a major strength, providing consistent nutrition for up to 10 weeks, reducing the frequency of application and supporting healthier soil over time. This feature is particularly beneficial for users looking to minimize maintenance efforts while maintaining a vibrant lawn.

Another highlight is its low-salt, organic composition, reducing the risk of plant stress and dehydration, crucial during hot weather conditions common in areas where centipede grass grows. Additionally, Milorganite is enriched with iron, promoting a lasting green without staining concerns, a practical benefit for homeowners concerned about nearby surfaces like walkways.

However, the absence of phosphorus in the N-P-K ratio might not be ideal for new grass establishment, as phosphorus contributes to root development. Users should consider this if starting new lawns. Also, while it covers 2500 square feet, heavier lawns may require more product investment.

Milorganite’s compatibility with various soil types makes it versatile, yet users should ensure their soil pH matches the needs of centipede grass for optimal results. Lastly, while safe for edible gardens, users should be aware of the product's recycled material composition, in case of any specific concerns with organic materials.

In conclusion, Milorganite is an excellent choice for maintaining a dense, green centipede grass lawn with minimal hassle, while offering eco-friendly benefits through its recycled content. It's well-suited for those who prioritize long-lasting nutrition within a sustainable framework.
