  • Verify product analysis, longevity and rate for plants in your production system (for assistance, contact your regional ICL-SF Territory Manager or call ICL-SF Customer Service at 800-492-8255)
  • Consult rate tables printed on bag labels and product sheets
  • For incorporation, blend into growing media to ensure uniform distribution of cores
  • Do not over-mix (doing so could damage fertilizer coating)
  • Growing media should be used within two to four weeks after incorporating fertilizer
  • For top-dress applications, spread fertilizer evenly on container surface (avoid piling fertilizer directly against plant stem)
  • Irrigate after application (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)
  • Use caution when applying to plants being over-wintered under cover (if you can't monitor soluble salts and/or adjust irrigation practices, avoid Fall and Winter applications
  • Store in a clean, cool, dry place
