Cannot find a granular fertilizer matching the commonly recommended 15-5-10 formulation with 2% iron and 40-50% slow release nitrogen for St. Augustine lawn care in north Texas.

Retail fertilizer labels don't clearly show slow release nitrogen percentage, making it hard to find products matching specific agronomic recommendations.
