Osmocote® Exact Tablets 8–9 Month Fertiliser 14-8-11 + TE

Osmocote® Exact Tablets 8–9M provide a highly efficient and precise controlled-release fertiliser solution, delivering consistent nutrition for up to 9 months. Designed for professional growers and landscapers, each 7.5g tablet contains a balanced NPK analysis of 14-8-11 with added magnesium and trace elements, ensuring optimal plant health, strong root development, and vibrant growth. The innovative cone-shaped design allows for easy insertion into the growing medium, making application quick, clean, and highly accurate.

Supplied in a convenient 1000 tablet box, this product is ideal for large-scale applications and professional use.

Once watered, the environmentally friendly water-soluble adhesive dissolves, allowing the tablet to break apart into granules that lock into the growing medium. This prevents fertiliser loss and ensures nutrients remain available to the plant over time. The controlled-release technology responds to temperature, providing reliable nutrient delivery aligned with plant needs, making it ideal for container plants, hanging baskets, and nursery stock.

Osmocote® Exact Tablets are perfect for growers seeking consistency, reduced labour, and maximum nutrient efficiency. With pre-measured doses per tablet, you eliminate guesswork and ensure every plant receives the exact same level of nutrition—resulting in uniform crop quality and improved performance across your entire growing operation.
