Osmocote 5 5–6M 16-8-12 + 2.2MgO + TE Controlled Release Fertiliser

Give your plants precision nutrition with Osmocote 5 5–6M, the next generation controlled release fertiliser from ICL. Combining 16-8-12 NPK with 2.2% magnesium oxide and essential trace elements, it supports healthy growth, vibrant foliage and consistent plant quality over 5–6 months.*

Ideal for peat-free growing media, Osmocote 5 features NutriMatch-Release technology with an advanced S-shaped nutrient release pattern. Nutrient delivery starts gently, then increases as plants grow and demand more nutrition. This carefully matched supply makes it particularly well suited to peat-free composts, where nutrient buffering capacity can be lower.

The innovative OTEA system — Optimised Trace Element Availability — improves the availability and uptake of essential trace elements, helping plants achieve strong growth and rich, healthy colour.

Key benefits

• Ideal for peat-free and peat-reduced composts: nutrient release follows changing plant demand.

• Precision feeding: NutriMatch-Release technology supports efficient uptake and use of applied nutrients.

• Improved plant colour and quality: the OTEA system supports trace element availability throughout the growing period.

• Consistent nutrition: controlled release supports steady growth in container nursery stock, perennials, pot plants and bedding plants.

• Easy identification: brown colour-coded granules identify the 5–6 month longevity.

Choose Osmocote 5 5–6M controlled release fertiliser for dependable plant nutrition and confident peat-free growing.

Longevity is based on an average growing media temperature of 21°C. Release is faster at higher temperatures and slower at lower temperatures.
