So much has been written to try and answer the question: what exactly is permaculture? We can say that permaculture is the use and reuse of all aspects of an organic garden. The way it all fits together, uh. Well maybe it's best if we describe something that permaculture aspires to. You take one of the oldest life forms on earth and examine how it operates. look at trees. If we could get our man made systems to work with a quarter of the efficiency demonstrated by a tree we would be doing very well indeed.
Trees manage to transport their water from below the surface of the soil high up into the air by capilliary action. Trees are able to resist attacks by predators by providing such a bountiful supply of food energy that feeding animals is rather a part of the tree's life cycle and not a loss suffered by the tree at all.
Permaculture, in essence, tries to operate a farm in the way that anatural system might operate. A tree is an unbelievealy efficient way of making material and energy out of sunlight and soil. So as you learn the ins and outs of permaculture. As you learn to work with compost and bokashi, with a diverse selection of plants that work together rather than against each other's purposes. Exchanging nutrients in natural balanced cycles of decomposition and regeneration. Look to the trees. You can't go wrong when you emulate the plants themselves in order to create, nurture and foster plant life.
