  • Soil revitaliser addsorganic materials back into soil encouraging beneficial soil microbes and earthworms which, in turn, improve both soil texture and nitrogen content
  • Contains iron sulphate which corrects iron deficiencies in plants
  • Certifiedto meet the Australian Standard for Premium Composts


  • All garden soils, especially those that have been in cultivation for many years andwill benefit from the addition of organic materials in the form of quality compost to improve soil texture and quality and nutrient availability
  • Ideal for constructing new vegetable gardens or raised gardenbeds
  • Safe to use in soils that will be used for vegetables and herbs and as a mulch around edibles
  • Safe to use for new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots


  • Don't use in hydroponic growing systems or ponds
  • Don't use on lawns - use only specifically named lawn topdress soils on grassed areas
