NutriStar Azalea & All Acid-Loving Plant Food is specially formulated to give acid-loving plants the nutrition they need to thrive. With an NPK ratio of 9-13-11, this blend provides the perfect balance of Nitrogen for lush green growth, Phosphate for strong root systems, and Potash for vibrant blooms. Designed for plants that prefer acidic soils or struggle with iron deficiencies, it combines four acidifying sources to gently lower soil pH, three forms of slow-release Nitrogen to deliver both an immediate boost and long-lasting feeding, and two sources of Iron to prevent yellowing leaves caused by chlorosis. Enriched with 20% Cottonseed Meal, the formula also supports soil health and biology for sustained nutrition over time.
