1) Finding the right spot
The right spot for a raised bed should be in level, on solid ground and on a sunshiny space.
2) Measure the right size and dig out the foundation
The ground you are digging out you can use as a filling material later.
3) Start setting up the concrete walls
For the walls for a raised bed you can use different kind of materials such as wood. In our case we used concrete.
4) Securing the walls from inside and outside while setting up
As the concrete walls are heavy and long you should do this together with another person.
5) Filling with compostable biomass
You can fill your raised bed with a mix of organic compostable biomass. This could be shredded leaves or grass clippings for instance. In-between you can put a layer of sticks so that the air can circulate better. On top you should put a good soil mixture.
