Starter Fertilizer 15-20-10 +Iron

Lawn Synergy 15-20-10 Starter Fertilizer is specifically formulated to support early root development, uniform establishment, and steady growth during the critical first weeks after seeding or sodding.

This product is designed for new lawn installations, overseeding, and turf repair — not routine maintenance applications.

Why 15-20-10 Is Ideal for Establishment

• 20% Available Phosphate (P₂O₅) to promote aggressive root development
• 15% Total Nitrogen for steady early growth
• 10% Potash (K₂O) to improve stress tolerance and early vigor
• 4.7% Sulfur to support nutrient availability

This balanced nutrient profile supports young turf when root development matters most.

Advanced Nitrogen & Micronutrient Package

• 11.2% Ammoniacal Nitrogen for efficient uptake and reduced volatilization
• 3.8% Slowly Available Nitrogen from polymer-coated sulfur-coated urea
• Iron (2.38%) for improved early color
• Boron, Manganese, and Zinc to support overall plant health
• Premium SGN 220 particle size for even distribution

This combination delivers immediate support with controlled feeding during early establishment.
