I made two raised garden beds based on the Hugelkultur principle of using woody debris as a garden resource. Three quarters of the beds are filled with branches, logs and sticks, and then back filled with composted soil from our chicken and goats and topped with mushroom compost. Over the course of time, the branches and logs will break down and add lots of goodness into the soil. Once a year when I rotate the crops in the beds, I'll backfill with a good soil.
I chose Australian grown Pine H4 Microshades Sleeper 200 x 50mm sourced from managed forest plantations. Used in landscaping and retaining wall applications, this Pine is termite resistant and the treatment is suitable for use in vegetable beds and children’s play areas.
The cost of each garden bed is around $150. You can reduce the cost by dropping the height by a sleeper, or choosing different materials.
Both raised garden beds – as well as all four paddocks and 32 fruit trees – are connected to an automatic watering system.
There's no shading on the sides, just the top. I'm training Star Jasmine up the side and over the top as a natural cover.
Looking for a way to fill a garden bed on a low budget, Bunnings Workshop member rattle created a Hugelkultur raised garden bed layering the bed with logs, branches, bark, leaves, horse and cow manure, cardboard, soil, compost and pea straw.
