Controlled-release granular fertiliser

Osmocote Pro (3–4M) 500 g

For a clear and easy feeding plan at repotting time, Osmocote Pro (3–4M) is a practical choice for plants entering an active growth phase. Once mixed evenly through fresh growing medium, its fully coated granules gradually release NPK, magnesium and trace elements for 3–4 months at 21°C, giving potted ornamentals, seasonal plants, shrubs and small trees a reliable nutritional base.
