How To Use

  • 1. Verify product analysis, longevity, and rate for plants in your production system (for assistance, contact your regional ICL Territory Manager or call ICL Customer Service at 800-492-8255)
  • 2. Consult rate tables printed on bag labels and product sheets
  • 3. For incorporation, blend into growing media to ensure uniform distribution of cores
  • 4. Do not over-mix (doing so could damage fertilizer coating)
  • 5. Growing media should be used within two to four weeks after incorporating fertilizer
  • 6. For top-dress applications, spread fertilizer evenly on container surface (avoid piling fertilizer directly against plant stem)
  • 7. 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)
  • 8. 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)
  • 9. 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
  • 10. Store in a clean, cool, dry place
