When to use


  • The base ingredient, compost, is nature's own method for returning to the soil all the nutrients and other goodies that plants take out while growing
  • Soil improver adds organic materials back into soil encouraging beneficial soil microbes and earthworms which, in turn, improve both soil texture and nitrogen content
  • Contaings a professional Grade Wetting Agent to help prevent drying out and overwatering.
  • Contains Iron Sulphate for the prevention and correction of Iron deficiencies in plants.


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



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