Mushroom compost is environmentally friendly. It is organic, recycles waste and saves water.

"Mulching your garden is equivalent to halving your weekly watering. It means you can have both a lush garden and practice water conservation." – Sydney Water Managing Director, Paul Broad.

How to use mushroom compost in a new garden bed.

1. Spread mushroom compost on the soil surface 

2. Incorporate the compost into the top 10 to 30cm of soil 

3. Allow about 1 week for compost to settle and blend with the solid 

4. Sow the seeds or transplant the plants 

5. Water well initially

You save water with mushroom compost because it:

·         Stores up to 70% of its own weight in water

·         Improves transmission of water through the soil

·         Keeps the soil cooler in warmer weather and increases soil resistance to both wind and water erosion

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.

Mushroom compost is great for;

·         Most flowering plants

·         Trees and shrubs

·         Vegetable gardens and herbs

·         Establishing lawns

·         Not recommended for some native plants and acid-loving plants such as azaleas, camellias and rhododendrons

Mushroom compost:

·   Provides plant nutrients

·   Helps soil hold water

·   Changes soil pH levels

·   Promotes seedling growth

A recent three year research program by the Victorian Department of Agriculture and Rural Affairs showed that mushroom compost:

·   Contains almost all nutrients needed for good plant growth

·   Supplies the nutrients slowly

·   Aids seedling emergence

·   Improves the structure of the soil

·   Conserves soil moisture

·   Produces no harmful decomposition products
