Osmocote Landscape Formula | Controlled Release Fertiliser
Landscape planting and maintenance demand consistent nutrition without constant reapplication. Osmocote Landscape Formula is a controlled release fertiliser designed for garden beds and landscape use, delivering a steady nutrient supply for up to 6 months.

How to apply
- At planting: mix Osmocote into backfill soil, fill around roots, then water thoroughly to settle soil and initiate release.
- Established plants: sprinkle in a band around the dripline beneath the leaf canopy and cover with mulch. Apply once per year per season guidance.
- Pots: sprinkle at the recommended rate over potting mix and cover lightly with mulch.
- Self‑watering pots: make 10 cm deep holes a few centimetres in from the rim; fill with columns of Osmocote. Water from the top once or twice to start feeding. As a guide, three holes suit a 20 cm pot.
Safety and Handling
- Caution: may stain hard surfaces if wet. Avoid contact with paths and paving; if contact occurs, sweep off immediately.
- Always read the pack label and product instructions before use; refer to the SDS and pack label for full safety guidance.
Consistent, low‑maintenance nutrition for landscapes
With temperature‑responsive controlled release and a low‑phosphorus analysis, Osmocote Landscape Formula supports establishment and ongoing performance across mixed plantings, including many natives, while reducing labour through extended feeding intervals.
