Farmers Favorite 15-0-15 Fertilizer with Iron

Achieve a deep, dark emerald-green lawn without triggering explosive, unmanageable growth. Farmers Favorite 15-0-15 with Iron is a premium, phosphorus-free granular fertilizer specially designed for southern turfgrasses—such as Centipede and St. Augustine—as well as established lawns, sandy soils, and areas with phosphorus-restricted runoff regulations.

By combining equal parts Nitrogen and Potassium with a powerful boost of Iron (Fe), this professional-grade formula delivers an incredible visual "green-up" while building deep root systems and excellent heat and drought tolerance.

Key Features & Benefits

• Deep Green-Up Without Excessive Surge Growth: Enhanced with iron, which directly stimulates chlorophyll production to give your turf a rich, dark green color without forcing rapid blade growth that requires constant mowing.

• 100% Phosphorus-Free (0% P): Ideal for soils that already have high phosphorus levels, sensitive coastal watersheds, or turf types like Centipede that thrive in low-phosphorus environments.

• Premium Potassium for Stress Tolerance: The 15% soluble potash ($K_2O$) helps plants regulate water usage, strengthening cell walls to withstand high summer heat, heavy foot traffic, and winter cold.

• Perfect for Southern Grasses: Specifically formulated to meet the sensitive maintenance requirements of Centipede, St. Augustine, Bermuda, and Zoysia lawns.

• Uniform, Dust-Free Granules: Screened for consistent size to ensure even distribution when using standard broadcast, rotary, or drop spreaders.

Guaranteed Analysis

• Total Nitrogen (N): 15% — Provides steady, balanced turf feeding and growth.

• Available Phosphate ($P_2O_5$): 0% — Phosphorus-free for protected waterways and low-P soil needs.

• Soluble Potash ($K_2O$): 15% — Promotes deep rooting, disease resistance, and extreme weather hardiness.

• Iron (Fe): Enhanced with Iron for maximum greening power and prevention of yellowing (chlorosis).

• 50 lb. Bag

Recommended Usage & Application

• When to Apply: Apply in late spring once lawns are fully green and actively growing. A second application in late summer or early fall helps prepare the turf for winter dormancy.

• How to Apply: Apply using a calibrated broadcast spreader to dry foliage. Ensure even coverage to prevent striping.

• Pro Tip: Water thoroughly immediately after application. This activates the nitrogen and potash while washing the iron granules off the grass blades and into the soil, preventing leaf burn and maximizing root absorption. Note: Sweep any stray fertilizer off driveways, sidewalks, or patios before watering to prevent iron rust staining.
