Osmocote® Plus Trace Elements: Native Gardens

A no fuss, set and forget controlled release plant food for those who don't have the time or inclination to tend to each plant or garden bed individually. The smart way to fertilise - one application feeds continuously for up to six months

  • Low phosphorus formulation for Australia natives and other phosphorus-sensitive plants ( eg proteas, leucadendrons)
  • Safe and reliable feeding in just two easy applications a year
  • Releases nutrients at the same rate plants are able to take them up through the roots - no wastage or run-off into waterways and drains
  • Includes a wetting agent that helps water and nutrients soak in to the soil
  • Feeds for 6 months continuously

Feeds when plants need it

The release of nutrients depends on temperature - more when it's warm and plants are growing and less when it's cold and growth is slow

Sustainable & environment friendly

Osmocote uses advanced prill technology that ensures even and controlled nutrient release with no wastage

Controlled release mean feeding less often and more effectively; less frequent feeding is more economical and environment-friendly

Wetting agent

The added wetting agent improves water absorption into the soil or potting mix and helps plants take up nutrients

Iron & magnesium

Boosted levels of these and other trace elements keep leaves greener for longer and promote healthy growth


500g and 1kg

Suitable for

All phosphorus-sensitive plants including Australian natives, South African proteas, leucadendrons, leucospermums and serrurias

Other trees, shrubs, annuals, perennials, vegetables, herbs and fruit trees

Safe to use on new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots

How it works

  • The release of nutrients from the fertiliser depends on soil temperature, not soil moisture
  • When the weather is warm in Spring, Summer and early Autumn, plants need more food and the fertiliser releases quicker
  • In Winter, when soil and air temperatures are lower, plants need less food because their growth rate is reduced, and less plant food is released

How to use

  • Native Gardens can be used throughout the garden to promote healthy growth, beautiful flowers and generous fruiting
  • Use the rates in the table below as a guide for how much to apply OR broadcast over beds using 50-80g/m2


Application Rates

Ideal for Planting Maintenance
All Phosphorus sensitive plants including:

  • When planting out - mix Osmocote into the backfill soil. Fill around the roots in the planting hole with the enriched soil and then water thoroughly to settle the soil and initiate nutrient release
  • Established plants - sprinkle Osmocote in a band around the dripline on the soil (beneath outer perimeter of the leaf canopy) twice a year and cover with mulch. This is where the feeding roots will be, not close in to the trunk
  • Pots - sprinkle at the recommended rate over the potting mix and cover lightly with mulch
