ICL Blue-Max Coated Alum Sulfate 50Lb — Single Unit

Osmocote® Blue-Max™ E-Max 0-0-0, 2-3M Coated Aluminum Sulfate is formulated to enhance blue coloration in hydrangeas through the controlled delivery of aluminum sulfate and essential micronutrients. Utilizing polymer-coated E-Max Release Technology, the product provides a safe and consistent release pattern that helps reduce the need for repeated applications. The coated granules minimize the risk of overdosing and root burn while offering lower phytotoxicity potential compared to traditional drench applications. Designed specifically for hydrangea production, this formulation supports efficient color management while providing predictable performance throughout the release period.
