Forest gardens create a food-producing ecosystem that quickly becomes a rich and productive habitat.

These agroforestry gardens that use permaculture principles have the notable advantage of being significantly self-sustaining meaning that the labor required to maintain the garden may diminish with time. 

What to Expect? If this sounds like “the dream” for you, we have compiled the ultimate forest garden guide, to equip you with everything you need to know to get into forest gardening and establish and maintain a forest garden habitat that can feed you and your family for a lifetime and then some! 

What Is a Forest Garden?

Forest gardens are food-producing, low-to-no maintenance systems that are patterned after woodland ecosystems to become not only visually rich and productive gardens but also thriving natural habitats:

Forage food from a forest garden

These gardens use trees and perennial plants to yield a wide range of foodstuffs including nuts, spices, berries, herbs fruit, alongside annual crops that may be grown in raised beds, on frames, or up and alongside the taller plants and trees.

In these wild or outdoor pantries, you don’t harvest your food, you forage it, and if you are a canny gardener, there will always be something to eat all year round.

Agroforestry principles

The characteristic feature of the forest garden is its emulation of a forest or woodland with plants being layered or stacked by height, with ideally native species in keeping with the location and climate.

Create a habitat where nature takes care of itself

The secret of the forest garden is the creation of a fertile natural habitat that will promote beneficial relationships with local animals, insects, and plants.

This approach builds resilience in the garden and should reduce or even remove the need for continual cultivation, chemicals, pesticides, and man-made fertilizers.

The key benefits of forest gardens

If you are new to forest gardening, the concept of making trees and shrubs the foundation of your food-producing garden may be daunting.

Establishing a forest garden also takes time, so what are the benefits of getting your food forest up and running?

A forest in your garden!

This three-dimensional approach to gardening turns even the flattest and uninspiring urban backyard into a rich green haven.

You can escape to your forest garden and spend hours foraging for berries, fruit, or leaves to enrich your diet. 

Work with the land

Forest gardening is all about letting nature do what it does best.

You are creating an environment where plants, insects, and animals can establish beneficial relationships, just like they would have in mature woodland.

So you can let the squash vine climb a tree trunk or plant basil with your tomatoes.

A nitrogen-rich ground cover crop also protects and nourishes the soil for all the plants.

Boost the productivity of your garden 

By growing horizontally and vertically you can enjoy great yields of fruits and vegetables, even though you are not growing intensively.

The variety of plants means that you can produce a wide range of crops.

Throw in a couple of ducks for slug control and you may be entirely self-sufficient!

A low-maintenance approach to gardening

A forest garden is the smallholder’s secret as they design it to reduce the amount of work that has to be done to grow food.

Careful selection of plants and trees ensures hardiness and suitability for your climate.

Insightful companion planting and intercropping boost yields without additional labor.

Enjoy diverse crops throughout the year

The layered approach to the garden provides natural shelter and traps warmth, meaning that you may ‌achieve a longer growing season.

Forest gardeners carefully plan their gardens to include plants that have different harvesting times, to ensure a food supply throughout the year. 

Encourage biodiversity in your garden

A forest garden is not just for you.

This ecologically conscious and sustainable form of gardening creates a natural habitat where all creatures can benefit.

Ways to Protect Fruit Trees from Birds

By creating a garden that is in balance with nature, you’ll attract beneficial pollinators like bees, insects, and birds. 

Protect your soils

Forest gardening is a beneficial form of gardening for preventing soil erosion.

The trees hold the land together and the varying layers of plants cycle organic matter to create rich humus that sustains and nourishes your plants.

Dynamic accumulator species like comfrey help you by sending down deep roots and mobilizing sub-soil nutrients that other plants can use.

Forests? Trees? Will a forest garden work in my backyard?

Thankfully, you don’t need acres of woodland to establish a forest garden on your property.

Forest gardening denotes the principles used in creating and maintaining your garden.

This means you can have forest gardens that thrive equally in a city or on an expansive smallholding.

The main thing is that the arrangement of plants and their relationships take on a life of their own providing food for you and wildlife year after year.   

The history of Forest Gardening

Forest gardening is all about a return to the land and finding practical ways of making land productive without the energy and labor-intensive methods of contemporary crop-raising.

The British smallholder and agriculturalist Robert Hart coined the term “forest garden” in the 1980s. He had sort to establish a self-sufficient farm for himself and his disabled brother.

Hart found the labor of maintaining a moderately sized smallholding too intensive and explored alternative, less intensive methods of farming. 

The concept of forest gardening is not new and is considered by some to be based on the Garden of Eden.

Cultures and communities throughout history and across the world have used forest-based polyculture for subsistence.

Examples include:

  • Keralan forest gardens, known as home gardens that combine fruit and spice trees with livestock and arable crops:
  • The rich and fertile Chagga gardens of Mount Kilimanjaro in Tanzania with bananas, pineapple, and arabica coffee as a cash crop.

If these lush, foliage-rich tropical settings seem a far cry from your suburban yard, it’s important to note that Robert Hart developed his forest garden in the UK which is USDA Zone 9.

Hart’s interpreted this ancient form of gardening as a seven-layer model that drew on the different layers of plants and organisms found in a forest.

In time and with much experimentation, his pioneering intercropping forest garden model proved ‌able to sustain itself with little intervention.

Other proponents of forest gardening come from the permaculture movement and include pioneers like Bill Mollison and Graham Bell.

Setting up a forest garden: the seven layers

Remember, with a forest garden, you are not planting a garden but building a living system.

Forest gardening has a big permaculture following and has many similarities in approach. Let’s run through the seven layers that make up a forest garden. 

1. The upper canopy 

Mature fruit trees make up the upper canopy of a forest garden.

This is the backbone of a forest garden and may also be described as foundation trees.

These are usually the original trees that were in place in the garden or grounds and include cropping fruit and nut trees.

The crowns of the trees form the highest layer of vegetation crop production in the forest garden but may have to be omitted in smaller gardens. 

2. The lower canopy or sub-canopy (Crab Apple)

Alternative names for this layer include the low-tree layer, understorey, underbrush, or undergrowth. It is directly beneath, or in front of the canopy layer.

Quince Fruit Trees

This layer consists of dwarf fruit and nut trees and can become highly productive very quickly when compared to the upper canopy.

In many cultures, this is where cash crops like coffee or olives are grown.

3. The vertical layer (vines and climbers) 

The vertical layer consists of climbing plants and climbers.

This can be an extremely practical part of any forest garden as it takes up little space.

By using the vertical space in your garden you can grow even more food at multiple layers.

Forest gardeners use frames, tipis, and even other plants and trees as scaffolding to support vines and climbers.

Just makes sure you have a ladder on hand for harvesting!

4. The shrubs, and bushes layer

These perennial plants grow closer to the ground and often require little maintenance other than to prune back over-enthusiastic growth.

Most plants in this layer, which includes many berry varieties, grow no more than three meters in height.

Healthy Garden trees

Along with food plants, some forest gardeners also include herbaceous plants with medicinal properties in this layer. 

5. The herbaceous layer (perennials and annuals)

This layer includes more conventional gardening selections.

These plants grow, flower, fruit, and die back every year and do not have woody stems.

With careful selection and planting, many of these plants can be reasonably low maintenance and relied on for good cropping.

The herbaceous layer protects the soil from erosion and leguminous plant species will add back beneficial nitrogen.

The herbaceous layer is also a magnet for the pollinators, beneficial insects, and birds that will do the hard work of getting your plants and trees fully pollinated.

6. The ground cover layer

Forest gardeners tend to this area with spreading, edible plants that create a forest floor.

Understandably, these plants have to be shade-loving and most ground cover plants grow close to the ground, ideally covering all the exposed soil in the garden.

It often overlaps with the herbaceous layer with both layers combining to form a single layer to garden. 

7. The roots and rhizosphere layer

The productivity of a forest garden spreads beneath the soil with plants that have nutritious storage organs growing beneath the soil.

There is a ‌large range of plants that have edible roots and gardeners may cultivate some of these species as part of the herbaceous and ground cover layer. 

Optional or additional forest garden layers

Depending on your terrain and natural resources you may add or remove layers from this model to achieve the forest garden effect.

There are an additional two layers that you can introduce to the forest garden if you have suitable land.

8. The fungal layer

Forest gardeners also cultivate mushrooms and fungi like Chicken of the Woods along with fungal species that colonize the soil.

This is a new layer that recognizes the beneficial effects of fungi on the quality of soil and plants in a forest garden.

Wild fungi growing spontaneously are a sign of a thriving forest garden.

9. The aquatic layer

Streams or ponds may be incorporated into a forest garden as an aquatic or wetland layer.

Water is not only a source of irrigation but also an ecosystem that can provide edible plants and a welcome habitat for local wildlife and ducks if you keep them for slug-eating. 

80 trees, plants, and crops for a food forest

Creating a forest garden is not only about producing food but also focused on creating a healthy ecosystem that benefits local wildlife and plants just as much as serving human needs.

This type of organic gardening requires a long view, as the plant established (especially in the upper layer) may produce for successive generations.

Here are 100 plants to consider including in any forest garden.

How to create your forest garden

Getting your forest garden layers to become established and working together is a labor of love.

Be prepared for lots of experimentation because things may not work the first time.

It can take years of working on a forest garden to develop a garden that is self-sustaining with the right relationships between individual plants, but once you achieve these the rewards of a continual supply of readily foraged food is well worth the wait!

Here are the key steps for starting a food forest in your garden.

Research

Learning, or the recovery of knowledge, is a big part of forest gardening and permaculture.

Thankfully people who are further along on your journey in forest gardening are more than happy to share.

Read books, watch videos and reach out to agroforestry organizations for ideas and advice to get your plans off the ground.

Plan

A forest garden is a long-term project that you set in motion.

Careful planning is required to achieve results that will be not only productive but also practical and visually pleasing.

You may want to obtain professional help from a garden designer, landscaper, or agroforestry specialist who can help you turn your ideas and aspirations for your forest garden.

Soil testing and other measurements will help you select the right plants for your land.

Food forest expert James Prigioni provides some great tips for how you can set things up:

Source

If you are planting fruit trees for your forest garden invest in high-quality saplings from a reputable nursery.

Perennial plants can be purchased or started from seeds.

Again investing in good quality plants like asparagus crowns will ensure you enjoy reliable cropping year after year. 

Plant

The different heights of the layers of your garden will produce a stepped effect.

But there are still many ways in which you can be creative with your plantings.

Here are some strategies you can try:

  • Protection for young trees
  • Tipis, frames, or trellis for climbing plants (alternatively they can climb trees)
  • Terraces, to make use of natural gradients in your garden to trap light and heat.

Wait

With forest gardening taking your time is a virtue.

These gardens do not respond well to excessive weeding, tilling, and other forms of “interference”.

Simply support the plants in establishing themselves and the mutually beneficial relationships that will help your garden to thrive.
