They embody one of the main concepts of Permaculture- "Stacking Functions" which means that one element in an abundant and sustained system cannot perform just one function. It needs to build symbiotic relationships with several other elements in the system. Instant Garden beds do just that and contrary to its name they can be applied to large scale commercial production, roof top gardens, balcony spaces etc. They retain a great amount of water because of the method of construction. A slow aerobic decomposition ensures that no manure needs to be applied. They greatly nourish the soil underneath while providing a yield up top. They keep back the grass and thus take away the need for constant weeding. They even allow you to recycle.
Here is a simple understanding of how we put together our first experimental bed through a slide show. This bed is also an experiment on cultivating near/under eucalyptus trees which areallelopathic. A great big thanks to Rico Zook (www.i-permaculture.org) for leading this first build. We are planning several more so keep checking our calendar for the next build and join us,.
