The inclusion of seaweed granules supplies more than 60 naturally occurring elements that complement the core nutrients, helping plants access a fuller nutrient profile during regular feedings.

In addition, the formula contains sulfur, boron, copper, iron, manganese, molybdenum, and zinc, plus seaweed granules that introduce more than 60 naturally occurring elements.
Yes—when used according to the label directions, this granular formulation is convenient for scheduled feedings and stores well in a cool, dry place. Keep the bag sealed between uses and avoid applying more frequently or at higher rates than recommended to prevent nutrient imbalances.
