It's a great urban garden strategy - easily tucked into small space gardens. I love them in my no-dig gardens, but they are suitable too for raised beds and even large pots.
Take a look at this short film (7 mins) I just made in my garden to explain the concept and show you how to make one.
Also take a look at a previous post I have written on this topic:
- Worm Towers - a quick and easy way to turn food waste into garden fertiliser - without digging or turning.
Take a look at my other short films:
Film #2: Our Permaculture Life: Community Permaculture Garden (9 mins 30 secs)
At the Yandina Community Gardens - I'll be teaching a Permaculture course there each Friday from 23 September.
My presentation at the Queensland Garden Expo in July 2016 about the incredible edible plants I love to have in my garden and why.
