Inc. GST + FREE Shipping
  • Osmocote Exact tablets provide the ultimate in convenience for a high analysis controlled release fertiliser with a complete range of essential nutrients. Simply push in the fertiliser tablets into potting mix, and walk away, knowing your plants will receive all the nutrition they need!

    Osmocote Exact tablets are a premium, controlled release high-analysis fertiliser, providing a practical option to provide precise nutrition to plants growing in pots, for 8 - 9 months, ensuring healthy plant growth. Osmocote Exact tables are a popular option for advanced trees, hanging baskets and planters, where it may be impractical to provide nutrition more frequently.

    Osmocote Exact tables are made from a very high analysis fertiliser containing all the essential nutrients required for healthy plant growth and is suitable for most plant types including flowers & ornamentals, fruit trees as well as bonsai (at lower application rates). Osmocote Exact tablets are built with an environmentally friendly adhesive which is water soluble. After watering the plants, the tablets fall apart and are locked within the growing medium. The individual fertiliser granules are fully coated with a new generation matrix which provides constant and extended nutrient release (for 8 - 9 months) therefore helping growers avoid surges and leaching of important plant nutrients which belong in your pots or garden soil, not in our precious waterways.

    Osmocote Exact tablets are a professional grade product used widely by the nursery industry in Australia, particularly in the cultivation of perennial plants in pots and planter bags.
