The Andersons Professional PGF Complete 16-4-8 Fertilizer with 7% Humic DG 5,000 sq ft
The Andersons PGF Complete fertilizer offers a carefully formulated 16-4-8 NPK ratio ideal for Bermuda grass growth. This formulation includes phosphorus-free nutrients enhanced with 7% humic acid, which helps improve nutrient uptake and soil health. The product features MUtech coated slow-release nitrogen, offering uniform growth and extended feeding without premature nutrient loss common with other coated fertilizers. The DG particles used release nutrients naturally, reducing dependency on physical coatings vulnerable to lawn mower damage.
Scotts Turf Builder Grass Seed Bermudagrass with Fertilizer and Soil Improver
This Scotts product combines Bermudagrass seed with fertilizer and soil improver, designed specifically for full sun and drought conditions. It includes root-building nutrition to strengthen new and existing lawns. The seed blend is highly drought-tolerant and best applied in late spring or early summer. Although the exact NPK ratio isn’t specified, this product supports healthy establishment and ongoing vigor for Bermuda grass.
Scotts Green Max Lawn Food, Lawn Fertilizer Plus Iron Supplement
This dual-action lawn fertilizer delivers nutrients alongside a 5% iron supplement to rapidly enhance grass greening within three days. While tailored for any grass type, its fast-acting formula is beneficial for Bermuda grass during the growing seasons of spring, summer, and fall. The product focuses on rapid recovery and deep greening rather than a specific NPK ratio.

Buying Guide: Choosing the Best Fertilizer Ratio for Bermuda Grass
Selecting the optimal fertilizer for Bermuda grass depends on the nutrient balance and application method best matching your lawn’s condition and climate.
Nitrogen (N)
Nitrogen is the most critical nutrient for Bermuda grass, promoting vigorous green growth and dense turf. A higher nitrogen content (around 15-16%) supports fast recovery and thickening, especially during active growing seasons.
Phosphorus (P)
Phosphorus supports root development but is generally less needed in established Bermuda lawns, especially in soils already rich in phosphorus. Many fertilizers for Bermuda grass feature low or zero phosphorus (e.g., 16-4-8 or 15-0-15), aligning with soil test recommendations and environmental regulations.
Potassium (K)
Potassium enhances drought tolerance, disease resistance, and overall turf strength. Bermuda grass benefits from adequate potassium, often balanced with nitrogen in ratios like 16-4-8 or 15-0-15 to strengthen roots and improve stress resistance.
Other Ingredients and Features
- Humic acid improves soil microbial activity and nutrient uptake, enhancing lawn vigor.
- Slow-release nitrogen sources provide steadier feeding and reduce nutrient leaching.
- Inclusion of micronutrients like iron accelerates greening and polish lawn aesthetics.
- Liquid fertilizers may allow quicker nutrient absorption and flexible application but may need repeated use.
Application Timing and Frequency
For best results, fertilize Bermuda grass during its active growing periods—spring through early fall. Match the fertilizer ratio and product type to soil tests and local climate. Over-fertilization, especially with nitrogen, can lead to thatch buildup, so gradual, consistent feeding is recommended.
Seed and Fertilizer Combinations
Products blending seed, fertilizer, and soil improvers support new lawn establishment, improving root development and soil quality. For new Bermuda lawns, consider such formulations for optimal initial growth and drought resistance.
Environmental Considerations
Choose phosphorus-free or low-phosphorus blends in areas with runoff concerns. Slow-release technologies help prevent nutrient loss to water bodies and ensure lawn health over longer periods.
