Food forest
One of my earliest memories of visiting my grandparents’ farm was playing on the dry stone wall, tossing stones around, and just generally fooling around.
Then, looking down, I came across a small seedling sticking out the side of the wall, growing in nothing, with barely any soil between the stones.
Out of childish curiosity more than anything I decided to set it free from the heavy stones and leave it to grow on its own. That was 20 years ago…
Today, that seedling is this strapping young fellow on the image left – European Ash tree.
He has survived the droughts, heavy snows, pouring rains, and sub-zero temperatures all by himself, without anyone taking care of him.
As I sit under his shadow today and plan my food forest I’m curious to find out how trees flourish without human intervention.
How come wild apples, plums, and cherries from the nearby forest do so well while the cherry tree I planted in my orchard five years ago has died miserably? To understand this I needed to return to the place where the seed of this Mountain Ash tree came from and revisit my teacher – the forest itself.
Forests Are Our Teachers
Just by my house, some 50m away is an entrance to a forest. I visit there often, it makes me feel relaxed, I enjoy the serene sounds of nature, the falling leaves, birds, and other critters. Most importantly, I go there to observe and learn.
You see, given enough time every ecosystem ends up like a forest. This is the endpoint of ecological succession; a point where the ecosystem becomes stable or self-perpetuating as a climax community and, without any major disturbances, the forest will endure indefinitely.
This is exactly what you want your own food forest to be like. To achieve a low maintenance abundance of fruit, nuts, berries and herbs you’ll want to create a forest-like system where fertility comes from various sources, where you’re greatly aided by fungi, where wildlife is your primary pest control, where soil holds water like a sponge, and where you have a high diversity of plants.
You want a carefully designed and maintained ecosystem of useful plants and emulate conditions found in the forest.
However, the problem is often that you’ll find yourself starting out with a bare field, a blank canvas and the overall plan can feel a little overwhelming. Sometimes even reading books such as Edible Forest Gardens can make things harder rather than easier.
While creating my own food forest, I broke down the plan into smaller, manageable steps. I want to make as few mistakes as possible and to be honest, I don’t have time to make them.
So today I’ll let you in on my process and I’ll also share additional resources that will help you go from that bare field to a fully-functioning ecosystem inspired by forests.
Ok, let’s dive in!
1. What Do You Want From Your Food Forest?
First, you have to be clear about the ultimate goals of your project.
Why is this important?
You see, with a clear goal, everything becomes easier, you know where best to place your efforts and, most importantly, what are the priorities, what to focus on and what to postpone for the time being.
You have to think are you doing this because of: 1. being more self-reliant, 2. making an income, 3. producing healthy food 4. educating others 5. having a fun project for all the family
As you can see, each of these will require different considerations for your precious time and money. For example, if your goal is to create an income from your food forest, you’ll want to focus on researching which tree crops sell well locally and then think about how to grow them in the most efficient manner.
On the other hand, if you just want to be more self-reliant, you’ll want to think about how to create a diverse food forest with as many fruits, nuts and herbs as possible to fulfill your needs and stop being dependent on the grocery store.
Don’t overdo the thinking at the outset, but just be clear what you want from the beginning.
2. Explore, Sit Quietly and Observe, Analyse
–> Explore your local forest so you’ll have an idea what will grow best in your area
Start with taking casual walks in your local forest. When designing a food forest you want to learn from the local ecosystem and try to emulate it. This is why such observations are important, this is how you discover what plants will grow best in our area.
You’ll want to look around and identify the plants that are thriving. As Mark Shepard would say: identify the perennial plants, observe how they grow in relation to one another, and take a note of the species. Later on, you can use that list to find commercial productive variants of the wild plants that you can grow in your food forest.
This step is crucial, because if you want to create an edible landscape that requires less work and maintenance, you need to grow species that are well adapted to your area, i.e. species that are volunteering to grow around your site.
If you have nature as your ally and use the natural tendencies of the native vegetation, then you’ll be doing considerably less hard work. This is one of the fundamental permaculture principles of working with nature rather than against it.
For example, when I walked in my forest I saw elderberries, hazels, hawthorns, lindens, cherries, apples, junipers, and the list goes on. So, guess what I’ll be growing in my food forest?
I’d also be taking seeds from those naturalized species and using them as rootstock for my plants. But that’s a lesson in itself, so be sure to read my post on growing trees from seeds.
–> Sit quietly and observe your site
Next, sit at the future site of your food forest, no matter if it’s 5 or 50 min, just sit there quietly. Brew yourself some coffee or tea and just be mindful of what is happening around you. Immerse yourself and study the wildlife, feel the breeze, listen to the sounds of the natural world around you. You can learn a great deal simply by sitting quietly.
One of my best ideas, and one that saved me a lot of time, came when I just sat down and observed my site. For years, I tried to get a wild hedge under control and year after year I was cutting it, but it kept on re-sprouting. This mindless management involved a great deal of work, as I always found myself battling against the hedge’s natural inclinations.
It wasn’t until one day, when I was sitting quietly looking down at the hedge, that I came up with an easy solution to the problem. I asked myself a simple question: How can I let nature do the work for me? As I observed the hedge more thoughtfully, I realized that some of the species growing there were actually useful, while with others, I had even planned to grow them there anyway.
If I just gave a head start to species I want there, they would eventually overgrow the ‘non-useful’ ones, and I wouldn’t need to mindlessly cut down everything each year. Sometimes we are just too much in working mode to come up with solutions that are actually a whole lot easier. Having the time to observe, think and ask the right questions helps us save money, time and unnecessary labor.
These moments of mindfulness help put things into perspective and reveal a wealth of important information about the site itself.
–> Do a site survey and make a basic map
It’s time to put on your permaculturist explorers’ hat and take notes about your site. You’ll want to ‘read the landscape’ and note down everything you can decipher about your water situation, climate, soil, slope, aspect, wildlife…
The landscape you see around you and its resulting ecosystems are formed from the interaction of climate, landform, soils and living things. Therefore, to better understand your site, you should analyze these elements, or parts of them, one by one…
At this point, you want to be actively involved and walk the site, conduct surveys and look at different natural processes. You can use modern technology (smartphones and desktop computers) to help you understand the weather patterns, terrain shape, and water movement across the land.
You also want to get your hands dirty and investigate your soil’s texture, structure, and biological activity. You can also perform some lab tests on your soil and experiment with some basic tests yourself.
There are many things you’ll want to explore during a site survey. Download my free site survey checklist and use it as your reference during this phase of the design.
Based on the information you’ve collected, make a rudimentary hand-drawn map or use Google Earth as a base layer and annotate the printout with your notes. You can even make multiple thematic maps for each of the landscape components you’ve analyzed.
From the map, it should be visible where the site potentials lay, and what you’ll need to design for.
3. Food Forest Design – Create a Layout and Choose the Plants
–> Choose a general layout – orchard, woodland, savannah
There are four basic layouts that determine the final look of the food forest: In their book, Edible Forest Gardens, Dave Jacke and Eric Toensmeiersuggest more options but I’ll round it down to the basics:
- Savanna type systems – alley cropping and silvopastoral system – examples: Mark Shepard/Grant Schultz
- Orchards – woodlands with regularly spaced trees – examples: Permaculture Orchard, David Holmgren
- Mid – to late succession woodland – this is what we are trying to emulate – examples: Robert Hart, Martin Crawford
- Closed canopy forest – end point of a succession – these are mature forests – example: “Your local forest”
Which layout suits you best depends on your goals and your site’s characteristics (climate, terrain, biome, etc.). Different systems require a different design approach, management, and maintenance….
Savanna-type or agroforestry systems are based on a keyline design and are much better suited for commercial fruit, nut and herb production. Usually implemented on a broadacre scale, this is a layout with equidistant rows that enables efficient machine harvesting.
The woodlands we call orchards are more of a hybrid system that you can use for both commercial production and home use. The layout also has equidistant rows, but permaculture orchards are usually implemented on a relatively smaller scale.
Mid- to late succession woodlands offer the opportunity for the most varied, interesting, complex, and productive patterns of trees shrubs and herbs. Although primarily geared towards home food production, you can implement this layout on your suburban backyard but also scale up to a farm scale.
–> Start by outlaying your infrastructure first
Start your design with the scale of permanence in mind and plan your water, access and structures first. It’s best to begin with these essentials because they will be the most permanent elements of you food forest.
This includes thinking about the most suitable places for your water tanks, irrigation lines and other water elements, as well as planning for the locations of access points, different buildings and fences.
Water planning comes first, as water is the number one priority for any permaculture system. The water systems that you develop in this stage will become permanent land features that other infrastructure components will follow.
Immediately after designing the water systems, consider where to put your roads and paths. Their placement will define your movement around your food forest for many years to come, so think long and hard about their potential locations. Once they’re in, it’s hard to rearrange them.
The pattern of the fencing will generally follow that of access, and you’ll be able to subdivide your food forest into different growing zones. By doing so, you’ll be able to manage and protect them separately if necessary. Finally, consider where to put different buildings, if any…
Good infrastructure design is essential in order to minimise maintenance, maximize productivity, and provide a habitat for beneficial animals.
–> Make a list master list of plants you wish to grow
Make a master list of plants – your desired species and others necessary to fulfil a certain purpose in your food forest. Think about ecological functions needed throughout the garden such as food production, the gathering and retention of specific nutrients, beneficial insect nectar plants, and ground cover for weed control.
Create a spreadsheet with each of these categories, do the research and list all the plants you want. Now, if there is a desired species that simply won’t work on your site, you can always find an ecological equivalent, i.e. an ecologically similar species that fills a similar community niche in comparable habitats.
For this, you can use climate-analogous species. Based on the climate classification of your site, you can find almost identical climates across the globe, and then, by researching plants in those areas, find all kinds of interesting species you didn’t know you could grow.
However, growing plant species that aren’t native to your bioregion can be working against the natural tendencies of your site. You can make things easier on yourself and only focus your attention on what’s proven to work. Here’s what I mean…
Based on the inspection of your local forest in step 1, you’ll have an idea what species grow best in your area. These native and naturalized species are part of the already functioning and thriving ecosystem. All you need to do now is imitate that ecosystem on your site but use the more productive variants of these species.
Be sure to include these plants in your master list!
–> Create guilds from your master list of plants
This is the very core of forest gardening. You want to create effective polycultures that share the resources and mutually support themselves. But how can you choose the right combination of plants? Here are just a few of the recommendations from Edible Forest Gardens.
You can do your guild build based on what you know or guess about plants, their species niche, and how they interact. In this way you can also create novel plant combinations through your experiments.
You can create a random mixture. A lot of people will just select a group of interesting plants and throw them together and see what happens. However, while it is sporadically ok to do so to spice things up, if the whole garden is like this, it will probably result in failure.
You can also try to emulate a habitat and use a model ecosystem as a template for design, incorporating species directly from the model habitat. This model habitat could be your local forest.
This is, of course, the easiest way to win. Here, you’re not inventing anything new, rather you’re copying what already works in nature. All you need to do is observe how the native plants grow in relation to one another and imitate that in your food forest.

–> Do a patch design – define your planting areas and plant spacing
Design your patches one by one, a patch could be a row, a contour or a grouping of plants in one area. However you decide to tackle the patch design, the most important aspect is deciding on the planting distance.
If you followed the design process and started your design by choosing the overall layout, you should already have an idea on the distances between the patches. Now let’s look at how to space the plants within the patch itself.
The easiest way to determine this spacing is by using the ‘crown touching rule’ and placing the individual trees a crown’s diameter apart. For this, you’ll have to find the information on the size of the individual mature trees’ crowns and use that as your guide.
Usually, the biggest mistake people make is overly-dense spacing where tree crowns are interlocking. This is OK when you’re planting a screen or hedge, but otherwise, this will put stress on the plants and limit their growth.
In his book, Creating Forest Gardens, Martin Crawford recommends adding 30-50% more distance around each woody plant if you want more sunlight for understory plants. Also, you want to plant wider than ‘crown touching’ distance when soil conditions are limiting, in order to reduce competition between plants for limited resources.
4. Prepare the Future Food Forest Site
–> Adapt your site if necessary
If you’re not starting from scratch with a bare field, the chances are there is something already growing there and you’ll need to adapt your site accordingly. This means clearing unwanted vegetation and leaving whatever you find useful. You can use any available biomass for mulch, compost, wood chips, firewood, mushroom inoculation….
For example, I will be leaving some naturalised plums and using a wood chipper to create some mulch from the trees and branches I don’t need, plus I’ll be using the wood for my hugel beds.
–> Shape the earth to your advantage and optimize water retention
After you cleared the vegetation, you can start the earthworks for optimizing water retention on your site. This involves shaping the earth in a way that promotes water infiltration, distribution and storage.
Effectively, what you want is to do first is to slow, spread, and sink the water as it falls from the sky into the soil. The soil is the cheapest place to store water, and it’s the largest storage resource available on most sites. To do this, you can use two very famous techniques: keyline plowing/subsoiling and swales on the contour.
Following this, you want to have a way to capture as much water as reasonably possible and store it for dry periods. You can do this by digging ponds that will store the water and diversion drains that will collect and distribute that water when necessary across the site.
Whether you’re going to use one or both of these strategies depends on your site conditions: climate, terrain, soil, your context…I think one question on everybody’s mind is whether or not to swale it. For assistance, I would encourage you to look at this cheat sheet by Ben Falk if you’re in two minds about doing swales on your site.
–> Set up infrastructure and put down irrigation, pathways, and fencing
Following the earthworks, begin with the most difficult, important or permanent elements of the food forest.
Start by putting down pathways throughout your site, they are important as they define your different growing zones and protect them from compaction. You want to minimize compaction in the areas you’ll be planting soon after and having clearly defined pathways keeps you on track (pun intended).
A well-built pathway can also act as hard surface runoff and collect the water that you can then connect with the other water elements you built in the previous step. Integrate rather than segregate!
Fencing the site is the next important thing. I can’t recommend building a main perimeter fence and enclosing your whole site strongly enough. Importantly, there are security issues and protecting from theft or trespassing and, moreover, I hear a lot of people regretting not doing this type of a fence first in order to ensure that their trees get protection from wildlife.
You don’t want those deer, coyotes, kangaroos, sheep or rabbits nibbling on your seedlings.
Finally, if necessary, put down irrigation and install water tanks – you simply can’t overdo it when it comes to making sure there is enough water during the months of drought.
