Picture yourself in a forest where almost everything around you is food. Mature and maturing fruit and nut trees form an open canopy. If you look carefully, you can see fruits swelling on many branches pears, apples, persimmons, pecans, and chestnuts. Shrubs fill the gaps in the canopy. They bear raspberries, blueberries, currants, hazelnuts, and other lesser-known fruits, flowers, and nuts at different times of the year. Assorted native wildflowers, wild edibles, herbs, and perennial vegetables thickly cover the ground. You use many of these plants for food or medicine. Some attract beneficial insects, birds, and butterflies. Others act as soil builders, or simply help keep out weeds. Here and there vines climb on trees, shrubs, or arbors with fruit hanging through the foliage hardy kiwis, grapes, and passionflower fruits. In sunnier glades large stands of Jerusalem artichokes grow together with groundnut vines. These plants support one another as they store energy in their! roots for later harvest and winter storage. Their bright yellow and deep violet flowers enjoy the radiant warmth from the sky.

What Is an Edible Forest Garden?

An edible forest garden is a perennial polyculture of multipurpose plants. Most plants regrow every year without replanting: perennials. Many species grow together: a polyculture. Each plant contributes to the success of the whole by fulfilling many functions: multipurpose. In other words, a forest garden is an edible ecosystem, a consciously designed community of mutually beneficial plants and animals intended for human food production. Edible forest gardens provide more than just a variety of foods. The seven F s apply here: food, fuel, fiber, fodder, fertilizer, and "farmaceuticals," as well as fun. A beautiful, lush environment can be a conscious focus of your garden design, or a side benefit you enjoy (see Figure 0.1).

Forest gardens mimic forest ecosystems, those natural perennial polycultures once found throughout the world s humid climates. In much of North America, your garden would soon start reverting to forest if you were to stop tilling and weeding it. Annual and perennial weeds would first colonize the bare soil. Shrubs would soon shade out the weeds. Then, sun-loving pioneer trees would move in and a forest would be born. Eventually, even these pioneers would succumb to longer-lived, more shade-tolerant species. It can take many decades for this process, called succession, to result in a mature forest.

We humans work hard to hold back succession mowing, weeding, plowing, and spraying. If the successional process were the wind, we would be constantly motoring against it. Why not put up a sail and glide along with the land s natural tendency to become forest? Edible forest gardening is about expanding the horizons of our food gardening across the full range of the successional sequence, from field to forest, and everything in between.

Besides the food and other products, you should design your forest garden for self-renewing, self-fertilizing self-maintenance. For a self-renewing garden, plant mainly perennials or self-sowing annuals. Allow a healthy soil community to develop by mulching and leaving the soil undisturbed. Build soil fertility with plants that fix nitrogen, amass soil minerals, act as mulch sources, or a blend of these. Reduce or eliminate your pest control work by providing food and shelter for insectivorous birds, and predatory and parasitic insects. Fragrant plants, such as onions, may confuse insect pests and slow their march toward your crops. In fact, you can reduce pest and disease problems simply by mixing things up, rather than planting in blocks of the same species! All these things, and more, reduce the amount of maintenance your garden needs and increase its yields. When we mimic how nature works and design well, we can reduce the work of sustaining ourselves to mulching, some pruning, occasional weeding, and minimal pest and disease management (depending on the crops you grow). Oh, and then there s the harvesting!

Essentially, edible forest gardening is the art and science of putting plants together in woodland-like patterns that forge mutually beneficial relationships, creating a garden ecosystem that is more than the sum of its parts. You can grow fruits, nuts, vegetables, herbs, mushrooms, other useful plants, and animals in a way that mimics natural ecosystems. You can create a beautiful, diverse, high-yield garden that is largely self-maintained.

Gardening LIKE the Forest vs. Gardening IN the Forest

Edible forest gardening is not necessarily gardening in the forest. It is gardening like the forest. You don t need to have an existing woodland if you want to forest garden, though you can certainly work with one. Forest gardeners use the forest as a design metaphor, a model of structure and function, while adapting the design to focus on meeting human needs in a small space. We learn how forests work and then participate in the creation of an ecosystem in our backyards that can teach us things about ecology and ourselves while we eat our way through it. Gardening like a forest is what this book is all about.

Gardening in the forest is different. We can transform an existing piece of woodland into an edible forest garden, and this book will explain how, but there are many other ways to garden in the forest. These include the restoration of natural woodlands, ecological forestry, and the creation of primarily aesthetic woodland gardens. The latter forms of gardening in the forest are not what this book is about. If you want to garden in the forest in any of those ways, see the resources listed in the appendix. If you want to grow food in a garden like a forest, read on.
