10 Best Fertilizer Centipede Grass 2025 in the United States

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.
