Planting a large number of fruit trees (including nuts if possible) is of major importance. Trees will save the planet! They store carbon, create a microclimate and perform many ecological functions while producing tasty and healthy crops. They require relatively little care, inputs and energy once planted. They are a balancing factor for humanity and for the entire biosphere.
Ideally a microfarm will have a large number of fruit trees (as orchard, hedge, forest garden). At Bec Hellouin, all of our gardens are now being managed within agroforestry.
Whenever possible one will implement tiered systems, above and below ground, combining, for example, fruit trees above red fruits, above other tall plants and vegetables. Such systems are more complex to install and require good management of light and water, but offer great benefits in terms of biodiversity, productivity and enjoyment.
