2 Bags of cow manure $10 1 Bale of lucerne hay $8 Making your own compost heap - priceless OK, so I've just built my first proper "heating" compost heap, aka the Geoff Lawton method, using layers of lucerne straw, cow manure and kitchen scraps. Temperatures here in Melbourne during the winter range from 2-15 degrees celsius, so only the inner core of the heap is heating up. To insulate the heap I have packed earth around the outside, since it is sitting in an open yard. It takes about two hours to create such a heap, and gets the heart pumping! Unfortunately I can only turn the heap once a week due to work commitments. The biggest hurdle in making such a heap in the suburbs is obtaining the materials- this heap has cost $18 for materials only, although next time I will try with free mulch from the council recycling depot. What stories do people have regarding sourcing of composting materials?
