Four pieces of round pressure treated poles are placed in each corner:
I’m using metal chicken wire to form a box. In the picture below you can get sense of the heavy sloping of the garden down towards the stream at the lower end. There’s a 10 cm (4 inch) gap in the right corner of the box due to the slope of the ground:
The lazy man’s guide to fixing chicken wire to a pole 😉 (I really have to cut down on my use of plastic cable binders – they don’t decompose well):
Finally I have room enough to store composting material separately before building the entire compost heap. Notice the open field in the background. It’s a pleasure to be this close to nature, instead of the bricks and concrete I was used to:
The reason for storing the different composting materials before building the heap is that the different materials will be more likely to get good contact with each other, because you’ll be able to spread out thin layers of each type:
In the past I used to throw in a very thick layer of grass cuttings each time I mowed the lawn (‘greens’), and much later I would throw in a lot of ‘browns’ and the materials would not get mixed and start to decompose. In small places a compost tumbler would be preferred as this would ensure that greens and browns would get properly mixed.
I watered my new compost heap after building so if everything goes well it will start to heat up and turn the waste materials into new compost to be used in the garden.
