Directions
  • consult rate tables printed on bag labels
  • verify product analysis, longevity and rate for plants in your production system (for assistance, contact your regional ICL-SF Territory Manager or call the ICL Lab at 877-467-8522)
  • irrigation frequency and volume should be adjusted during the crop production cycle according to crop type, environmental conditions and desired soluble salt levels
  • a product trial is recommended before adopting a new fertilizer program or making full-scale changes to standard cultural practices (test several rates on representative plant types)
  • store in a clean, cool, dry place

Specifically designed for petunias and other high iron demanding plants, this unique formulation contains three chelated irons, including black iron—the most effective for growing ornamentals.
