10 Best Fertilizer Centipede Grass 2026 in the United States

The Jonathan Green Green-Up Lawn Food with Crabgrass Preventer is designed to feed centipede grass effectively while also managing common weeds like crabgrass. Its N-P-K ratio is 20-0-3, providing a high level of nitrogen to promote green, healthy grass growth but containing no phosphorus. This is generally good for established lawns like centipede grass, which often do not require extra phosphorus. The fertilizer releases nutrients slowly over up to three months, helping to reduce the need for frequent applications and providing steady nourishment.

A key strength of this product is its built-in crabgrass prevention, offering both pre-emergent and post-emergent control, which can save effort on separate weed treatments. It is easy to apply with common spreaders and covers a large area (15,000 sq. ft.) per 50-pound bag. It should not be used when seeding new lawns, as it can harm seedlings.

If you want a product that combines feeding and weed control with less frequent applications, this is a practical choice. However, if your lawn needs phosphorus or micronutrients, or you prefer a phosphorus-inclusive formula, you might want to consider other options.

Jonathan Green Veri-Green Crabgrass Preventer Plus Fertilizer is designed to feed lawns while also controlling crabgrass and several other common weeds. Its nutrient ratio of 20-0-3 means it provides a good amount of nitrogen (the first number) to promote healthy grass growth but contains no phosphorus (the middle number), which is often fine since many soils already have enough phosphorus. The low potassium (the last number) supports overall lawn strength but is on the lighter side. This fertilizer releases nutrients slowly over up to 3 months, so you won't need to apply it frequently. It’s best used in spring before crabgrass and other weeds start growing, making it a solid choice if you want ongoing weed prevention alongside feeding. However, it should not be applied when seeding new lawns, so it’s not suitable if you’re establishing grass from scratch.

The product’s granule form is easy to spread without staining your hands or walkways, and one 50 lb bag covers a large area of up to 15,000 sq. ft. If you have centipede grass, which prefers low phosphorus fertilizers, this product’s zero phosphorus content aligns well with that need. This fertilizer focuses on nitrogen feeding and weed control, which works well for many common lawn soils.

This fertilizer is a convenient, effective choice for controlling crabgrass and feeding your established centipede grass lawn during the growing season with minimal effort.

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.
