plant food and soil improver designed for Roses, Gardenias, Azaleas and other plants loving an acid soil which combines the best of both worlds. Scotts Osmocote® Plus Organics nurtures plant growth both above and below the ground and by creating a balanced and sustainable growing environment, plants are healthier, stronger and less susceptible to insect attacks and diseases, season after season

When to use



  • Boosted levels of iron and magnesium help prevent the common leaf yellowing sometimes seen on these plants.
  • Gypsum breaks down clay soils, provides plants with the calcium they need to strengthen their structure and boosts disease resistance
  • The natural fertilisers blood & bone and composted manure boost growth and plant health and improve soil texture and moisture holding
  • Fish extract is a natural source of nitrogen, potassium and trace elements
  • Seaweed is a natural soil and plant conditioner and tonic that improves resistance to stress and trauma and helps plants recover faster
  • Scotts Osmocote® uses advanced prill technology that ensures even and controlled nutrient release with no wastage. The organics are all derived from renewable resources



  • Designed specifically for roses, gardenias, azaleas, camellias, rhododendrons and other acid lovers
  • Can be used on most small shrubs and some natives apart from those preferring an alkaline soil
  • Flowering and leafy potted plants, including indoor plants
  • 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 in hydroponic growing systems, ponds or pots submerged in water
  • Do not use on lawns - use only specifically named fertilisers on grassed areas
