If soil is seen as the slightly boring but hard-working underdog in the garden, then mulch is the flashier icing on the cake, while working just as hard.
Brendan investigates mulch at ANL and has much to say on the matter.
Mulching is where a thick layer of organic material or gravel is laid over an exposed area of soil. This will hinder the growth of weeds and help to retain moisture in the soil.
As the mulch breaks down the nutrients are added to the soil.
Leaf Mulch (leaf litter)
This is traditional mulch, which is great for native gardens at $34 per m³.
Pine Bark Horticultural Grade
Very commonly used and long lasting and is tan in colour. Fine (15mm) graded pine bark. Recycled by product from plantation timber at $50 per m³.
Greenlife Mulch and Compost

Fine (15mm) 100% recycled Grade A green waste and post consumer wood waste at $36 per m³.
The most popular mulch colour is red but there are many other colours available including black and green at $ 55 per m³.
Things to consider
- When laying out the mulch, fill a plastic garbage bag – this will make dispersing much easier. The mulch needs to be 7 to 10cm thick.
- Mulch in early spring to help your plants get through the hot summer.
