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 3rd 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.

Osmocote N is a fully coated nitrogen & potassium fertiliser. Coated with new advanced coating technology Osmocote N is perfect for pot and bedding plants, perennials and container nursery stock, providing extra nitrogen and potassium, especially required in peat-free and peat-reduced growing media.

Osmocote Topdress is a coated fertiliser designed especially for topdress application in container nursery stock. It can be used to achieve an immediate greening effect. It contains a high nitrogen, magnesium and iron content, to get an immediate greening effect. Containing fast- and slow- release nitrogen and phosphorous, it releases the correct amount of nutrients over a period of 4-5 months. The plants will be greener and stronger for optimum performance. 

With longevity of up to three months, and a fast-start portion, OsmoTop sticks to the growing medium surface, eliminating fertiliser losses. It can be used for a quick green-up, or to rectify deficiencies quickly in well-rooted container nursery stock.
