ICL Osmocote Pro 8-9 Months 18-9-10 2MgO+TE 25kg is a professional Osmocote Pro controlled-release fertiliser formulated for incorporation into growing media for container nursery stock.
Its resin-coated nutrients provide a measured supply over a nominal 8–9-month period at 21°C, helping growers match fertiliser longevity to their crop cycle.
Key benefits
- Fully coated NPK, magnesium and trace elements
- Predictable release for container crops
- Useful in nursery nutrition programmes alongside appropriately adjusted water-soluble feeding
- 8–9-month nominal longevity at 21°C
- 25 kg bag
Professional applications
Suitable for incorporation into growing media for container nursery stock. Plan nutrition around crop demand, irrigation water, substrate properties and any supplementary feeding.
How to apply
Mix granules evenly through the growing medium before potting, following the current manufacturer instructions. ICL advises against dibbling for the short-duration Pro variants; check the current instructions for the exact product before choosing any alternative application method.
Application rates & nutrient management
Container nursery stock: 3–3.5 g/L (light), 3.5–4.5 g/L (normal), 4.5–5.5 g/L (heavy).
Manufacturer rates are general recommendations for unfertilised substrates. Adjust to local growing conditions and other nutrient inputs. Trial programme changes on a small scale before wider adoption.
Storage & handling
Keep partly used bags sealed and store in dry conditions. Follow current ICL product information and safety guidance.

Frequently asked questions
What does the stated longevity mean?
ICL rates this product at 8–9 months at a growing-medium temperature of 21°C. Higher temperatures generally shorten the release period; lower temperatures extend it.
Can it be combined with liquid feeding?
Yes, where the crop programme calls for it. Reduce the controlled-release fertiliser rate appropriately when adding water-soluble nutrients to avoid excessive total feeding.
How should unused product be stored?
Reseal opened bags and store in dry conditions, following the manufacturer’s storage instructions.
How do I select a rate?
Choose a rate according to crop demand, growing medium, container volume, season and any additional feeding. The published rates are general starting points for unfertilised substrates; trial changes on a small scale.
Is this suitable for every crop?
No. Match the formulation and longevity to the crop, growing period and feeding requirements.
How does temperature affect nutrient release?
Nutrient release generally speeds up at higher growing-medium temperatures and slows at lower temperatures.
