I just read about hugelkultur and immediately got to work and built 2 largish beds chock full of a very old apple gum timber from a tree that had fallen.
Possum and wallaby proofing was top priority so I caged the garden with chicken wire
I transplanted some purple cabbage and sprinkled heaps of seeds for the 1st crop.
Total cost was $140au for the chicken wire but overall this garden should give me many years of quality organic produce.
