A set and forget controlled release plant food for those who don't have the time or inclination to tend every plant or garden bed individually. The smart way to fertilise - specially formulated for acid-loving plants and feeds continuously for up to six months

When to use



  • 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
  • Scotts Osmocote® uses advanced prill technology that ensures even and controlled nutrient release with no wastage
  • Controlled release means feeding less often and more effectively; less frequent feeding is more economical and environment-friendly
  • Wetting agent improves water absorption into the soil or potting mix and helps plants take up nutrients
  • Boosted iron keeps leaves greener for longer


  • All plants in the garden or in pots preferring an acid soil or potting mix and fertiliser (pH 5.2 - 6.2)
  • Roses in the ground and in pots
  • Safe to use on new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots


  • Do not use for plants preferring a neutral to alkaline soil and fertiliser (pH 7 and above)
  • Do not use in hydroponic growing systems, ponds or pots submerged in water
  • Do not use on lawns - use only specifically named fertilisers on grassed areas


  • Roses, Gardenias, Azaleas & Camellias will promote healthy growth and beautiful flowers on roses and other acid-loving plants
  • Use the rates in the table below as a guide for how much to apply OR broadcast over beds using 50-80g/m2


Area Planting Maintenance

Roses, Azaleas, Camellias, Gardenias,

Rhododendrons & other acid-loving plants

10cm pot = 2 TBL

15cm pot = 3 TBL

20cm pot = 4 TBL

Years 1-3 6 TBL per bush

Year 4 onwards 10 TBL per bush

Note: TBL - tablespoon = 15g

  • Established plants - sprinkle Scotts Osmocote® in a band around the dripline on the soil (beneath the outer perimeter of the leaf canopy) once a year and cover with mulch. This is where the feeding roots will be, not close into the trunk
  • Pots - sprinkle at recommended rate over potting mix and cover lightly with mulch
  • Self-watering pots - make 10cm deep holes* in the potting mix with a pencil or long skewer a few centimetres in from the rim of the pot and fill with columns of Scotts Osmocote®. Water from the top once or twice to start the feeding process

*The number of holes will depend on the size of the pot - as a guide, three equally spaced holes would be enough for a 20cm diameter pot
