A Food Forest is a forest filled with edible plants and trees. Another name for a food forest is a forest garden, which means a garden grown like a forest.
A food forest is composed of the same layers and components as a normal forest. A forest has an overstory of great trees that towers over all the other plants, then there are the small trees and bushes that fill the empty space between the gigantic trees and the ground, then there are plants that cover and are near the ground. They are the long twisty vines that are a web connecting every layer into one entangled living mesh.
So like a forest, the forest garden will be a living system with many layers of fruit and nut trees, berry bushes, aromatic herbs, and with a grapevine connecting them all.
In a food forest, there are 7 plant layers working in harmony together, the overstory trees, the understory trees, the shrub layer, the herbaceous layer, the ground cover layer, the root layer, and the vine layer.
The overstory layer is the canopy of the whole food forest, becoming the keystone plant of the whole system, influencing every other plant, never changing, but always having surrounding plants that changes constantly in their long lifetimes.
The overstory trees shields like the atmosphere of the plants under them from most of the strong winds, and cool the plants under them by blocking some of the light, creating a more moderate climate for the plants below to enjoy. The canopy trees are also a great habitat for birds and many animals. The big trees also shed a lot of biomass on the forest floor for the small plants to enjoy.
Examples of overstory trees are usually nut trees like walnut, timber trees like oak, or big fruit trees like apple trees.
The second layer is the understory trees, these trees are grown to be lower in height for ease of harvesting, and usually, these species are more delicate and dependent than the big overstory trees.
Examples of understory trees are usually shade-loving fruit trees like persimmon, or dwarf and semi-dwarf fruit trees like mulberry trees, peach trees, and nectarine trees, most of the fruit trees are located in this layer.
The third layer is shrubs which fills the gap between the small trees and the ground. Bushes can be used to protect the smaller delicate green herbs and plants from heavy winds. Bushes are the most versatile and diverse type of layer where you could plant for many different reasons like food, crafting, flowers, and also different places and sizes, shade to full sun, gigantic like a small tree to a small dwarf bush.
Bushes have among the most examples of different variations, too gigantic hazelnuts, too small dwarf lilacs, too shade-loving currants, and too sun-loving blueberries, so bushes come in different sizes and kinds.
The fourth layer is the herbaceous layer which usually grows in traditional gardens. This layer has vegetables, herbs, and flowering plants. The use of this layer is mostly to get the traditional herbs and vegetables as normal gardens, but also has flowers to attract pollinators.
Examples of the herbaceous layer are the normal veggies such as lettuces, too the normal herbs like parsley, and too beautiful wildflowers like asters.
The fifth layer is the ground cover layer. Every plant covers the ground, but ground cover plants especially do it by spreading and covering as much bare ground as possible, and usually low to the ground. The use of Ground covers is to blanket the ground so weeds won’t grow.
Examples of Ground Covers are strawberries, phlox, and any other low-growing ground covering plants.
The sixth layer is the root layer, the root layer is composed of all the other kinds of plants’ roots, but there are certain plants that specialize in roots. The plants that have big and deep tap root systems will break up any hard soils, and will break into the hard pan soils deep underground, untouched to any other roots, and bring the untouched nutrients up to the surface for the typical shallow rooted plants to use.
Examples of plants that specializes or are known for their roots are Carrots, radishes, Jerusalem artichoke, and Yams.
The seventh layer is the vine layer. The vine layer is a type of plant that fills the gaps between the different plants and layers making most of the space, maximizing and getting the most out of the land.
Examples of plants in the vine layer are grape vines, Passion vines, and melon vines.
The 7 layers are used to show what characteristics a natural food forest needs. Plants don’t always follow the categories of layers perfectly, some plants can be in many layers. Layers just show what categories of plants can be grouped together by their characteristics and their abilities. Certain plants can do many things making them qualified to be in many layers.
A food forest is an ultimate garden, where all the food needs of humans can be fulfilled, and where the garden maintains and grows by itself.
