Controlled Release Fertilisers

Having pioneered controlled release fertilisers over 50 years ago, our world-leading Osmocote range of products is still evolving thanks to innovative new technologies. The most significant difference between then and now is the level of applied scientific horticultural knowledge. Our most advanced, 5th generation, Osmocote fertilisers provide a choice of longevities as well as the way nutrients are released making these products unique. No matter which Osmocote controlled release fertiliser product is selected, growers can rest assured the highest quality and return on investment will be delivered.

Discover Osmocote 5 – the latest innovation from the Osmocote Green Lab. Building on years of research and development, this next generation controlled release fertiliser helps growers create the strongest, healthiest, highest quality plants. Thanks to the OTEA-system and nutrient matching technology, plants are greener, stronger and more resilient. Read more here.

Osmocote Bloom provides optimum plant quality through maximum nutrition during the entire crop cycle, plus the selling and early consumer stages. Osmocote Bloom provides plants with all food they need every step of the way from potting to the first consumer phase. Its 100% coated NPK analysis and traces are ideal for bedding plants with a two-to-three-month crop cycle. It’s especially effective for condensed growth in many annuals including petunias and geraniums. 

Osmocote Exact High K is a 4th generation controlled release fertiliser and has been designed to support compact plant growth where the irrigation water has high nitrogen levels. It’s the ideal solution for CNS crops and compact pot plants, perennials, and bedding plants. It also provides great results with species that need high potassium nutrition, including cyclamen, viola, and primula results in compact plants.  

Osmocote Exact Mini is perfect for use in small-substrate volumes such as plugs and trays. The fine granules (of between 0.85 and 2.0 mm) are smaller than Osmocote Exact Standard. This provides optimum nutrient distribution and uniform growth, in volumes as low as 20ml. The granules may be small – but each one is packed with every nutrient plants need.    Osmocote Exact Mini can be used to combine the rooting and repotting stages, rather than adding extra fertiliser via sprinklers.
