  • consult rate tables on bag
  • 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. Provides iron to plants over the widest pH range to encourage dense, compact growth.
