Spent Compost Uses

Spent Compost Uses

Mushroom compost is a scientifically developed recipe of recycled organic ingredients such as:

  • Stable bedding (including manure) wheat straw, poultry litter and cotton seed hulls which are pasteurised to kill any harmful bacteria.
  • As mushrooms are a multi-million dollar Australian industry, the compost in which the mushrooms are grown is vital. The compost provides the goodness on which the mushrooms flourish.
  • When the mushrooms have finished cropping, what remains is an ideal compost for the home garden.

“Gardens love mushroom compost as a mulch and soil conditioner. Best of all, you can
reap a new harvest out of a spent commercial product – that’s the ultimate in recycling.”

Ben Swane – gardening expert from the renowned Swane family

  • Conserves soil moisture
  • Produces no harmful decomposition products

*not recommended for some native plants and acid- loving plants such as azaleas, camellias and rhododendrons

How to use mushroom compost in a new
garden bed:

  • Spread mushroom compost on the soil surface
  • Incorporate the compost into the top 10 to 30cm of the soil
  • Allow about 1 week for compost to settle and blend with the soil
  • Sow the seeds or transplant the plants
  • Water well initially

You save water with mushroom compost because it:

  • Stores up to 70 per cent of its own weight in water
  • Improves transmission of water through the soil
  • Keeps the soil cooler in warmer weather, warmer in cooler weather and increases soil resistance to both wind and water erosion
