The Poly-S technology in Osmocote Blend 22-3-8 5-6 mo. ensures that nutrients are delivered at a constant rate regardless of climate or temperature swings.

N-P-K: 22-3-8

A popular general purpose product as an inexpensive base fertilizer mixed into the media or topdressed onto nursery containers. Fast-growing perennials, grasses and foliage plants respond very well to this formulation. It also make a versatile topdress for overwintered plants once they have been uncovered or lined out in the nursery. Another popular use is on container-grown conifers.

Economical choice for general purpose outdoor production

Benefits

  • Consistent release and accurate longevity across multiple temperature ranges
  • Highly efficient nutrient delivery promotes robust growth and maximum economy
  • Dual coatings reduce nitrogen leeching and decompose with minimal environmental impact
  • Fortified with STEP Hi-Mag micronutrients
  • Can be incorporated into growing media or surface-applied in the container

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 fertilizer
  • 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
