Osmocote Bloom provides optimum plant quality through maximum nutrition during the entire crop cycle, plus the selling and early consumer stages. Your plants will get all the 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 Hi.End is a high-tech programmed-release fertilizer, with pre-defined longevity and release pattern. With its Dual Coating Technology, 40% of granules have a second coating, so the product will only start to release 10-12 weeks after application, during the critical growing phase. This delivers highly effective nutrition and improved plant growth, meaning you can fertilize more effectively. Osmocote® Exact Hi.End is an excellent choice if you are cultivating plants with an increased nutrient demand in the second growing phase. Use for potted conifers and evergreen shrubs, or other container nursery stock that responds well to a low EC value in the first months after potting. Lower EC levels at the start of the cultivation period make it easier for crops to take root.

Osmocote Exact High K is a 3rd generation controlled release fertilizer and has been designed to support compact plant growth where the irrigation water has high nitrogen levels. It’s the ideal solution for your CNS crops and compact pot plants, perennials, and bedding plants. It also gives you great results with species that need high potassium nutrition, including cyclamen, viola, and primula. You’ll get big results in your 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 gives you 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 your plants need.    You can use Osmocote Exact Mini to combine the rooting and repotting stages, rather than adding extra fertilizer via sprinklers.

Fourth-generation fertilizer Osmocote Exact Protect’s 100% double-coated granules postpone nutrient release during the winter months. That means EC or salt levels in the growing medium stay consistently low for up to the first three months. Longevity is between five and 14 months, while granule size is 2.0-4.5 mm. 

Our first third-generation fertilizer Osmocote Exact Standard releases nutrition consistently throughout the growing season, in line with your plants’ requirements. This regular, continuous release makes it ideal for almost all growing situations. It’s especially well-suited to evergreens and deciduous shrubs, and when you can only apply one release pattern. You can also use it where plants’ nutrient demands are consistent throughout the growing cycle. 

Osmocote Exact tablets offers convenience and accurate rate of nutrient. Available in 5g and 7.5g, Osmocote Exact Tablets are cone-shaped so you can push them easily into the growing medium.  Using an eco-friendly, water-soluble adhesive that will start to dissolved once you watered them in.

Osmocote Pro is a second generation controlled release fertilizer. It means that not only N, P and K are coated but its granules contain all necessary trace elements. Osmocote Pro gives you consistently strong results. It comes in 4 longevities: 3- 4, 5-6, 8-9 and 12-14 months. It’s also distinctive thanks to its steady nutrient release pattern for optimum growth and performance. 

Osmocote Special Products are NPK and micronutrient mixes designed for specialized applications and varieties. Osmocote Bloom products are especially formulated for use on small container plants such as petunias, mandevillas, and geraniums. And our Blue-Max mix is the go-to product for growers who want only the brightest blue hydrangeas.

Osmocote Start delivers nutrition to your crops with a short cultivation cycle, or provides refertilization for up to six weeks. It’s designed especially for compact-growing annual plants with a short cropping cycle. These include violets, marigolds and primulas, along with more salt-sensitive vegetable crops, and cuttings that have difficulty rooting. 

Osmocote Topdress is a coated fertilizer designed especially for topdress application in container nursery stock. Use it to achieve an immediate greening effect. It contains a high nitrogen, magnesium and iron content, so you get an immediate greening effect. Containing fast- and slow- release nitrogen and phosphorous, it releases the correct amount of nutrients over a period of 5-6 months. You’ll benefit from greener and stronger plants for optimum performance.
