Osmocote Pro 8-9m controlled-release granular fertiliser gradually releases nutrients for 8–9 months at 21°C. The fully coated granules contain nitrogen, phosphorus, potassium, magnesium and trace elements. Mix evenly into the new growing medium before planting or repotting.
Its formulation contains three forms of nitrogen: nitrate, ammoniacal and urea. For plants in pots, the application rates are 3–4 g/L for low, 4–5 g/L for standard and 5–6 g/L for high nutrient requirements. For shrubs and trees in containers, the corresponding rates are 3–3.5 g/L, 3.5–4.5 g/L and 4.5–5.5 g/L. The release period is 10–11 months at 16°C and 6–7 months at 26°C. When adding a water-soluble fertiliser, reduce the dosage accordingly.
