Forest Garden: Winter 2013 Musings, Reflections, Intuition, and Goals


In February of 2012, I wanted to take a permaculture design course (PDC). There was one near my home that was affordable; however, at the last minute, despite finagling and scraping on my part to go, I had a very uncertain feeling. By this point, I was learning to pay attention to my uneasy feelings as a sign that something was not right for me. I listened and did not go. I am not sure why I had this feeling, however, I started paying more attention to the permaculture world as a result of not going, and I did discover some things that were disquieting.
Two months later, I had a chance to visit the farm of the PDC teacher; he needed help planting because he was behind in the growing season due to the demands of the PDC. I volunteered to assist him and was invited to come join him and others in a large-scale project. I was excited; this was a dream come true to finally see permaculture in action. If we got along then I would be accepted as a summer intern. He seemed to be an authority and a leader in the permaculture industry; this time would be fun. Unfortunately, it was not fun. I got to see a side of permaculture that I did not think existed; a side that shows its exclusionary, exclusive nature.

Needless to say, I realized that my exploration of permaculture had to be an internal journey where I learned to recognize and listen to my intuition rather than relying on some authority to show me the correct way. Do not get me wrong, I still want to take a PDC; however, I will do so to expand my knowledge not to fix my desire to dabble. I realized there was nothing wrong with me and my method. I desired to help the world; the world needed many different solutions because of the diversity of people on this planet. I realized that these authorities tried to pander a one-size-fits-all solution by putting everything into a neat, tidy, pigeonholed box. I still want to see how someone actually does forest gardening according to observation, planning, and proper plant placement; however, I only want to see what else is possible. I love my little forest garden and how we evolve together.

Today was a wonderfully warm, sunny winter day. I had not visited my little forest garden in a month or so; but I went today. Our winters are weird here; we are often in the lower 30’s in the day and overcast; but we have very little to no snow. Around mid-December we did have a few inches that stuck around for a few days; that was nice. But alas, it melted :( and we were back to gloomy days with no snow to look at. This winter has been milder than previous winters. My comfrey plants were green until December, and one plant still has a small portion of one leaf that is green. My strawberry plants are still green. Parts of the chicory and marigold plants are still green too. Of course, the grasses are still green in places; but they usually are. The odd thing is that there is some new growth: grasses and I believe some of my wildflower seeds are sprouting. For some reason, the huggle trenches are covered in green grass. I wonder if that area is warmer. I did hear somewhere that decomposition does happen in the winter and if that is the case then that explains the warmth. I suppose I could get scientific and measure the soil temp, but that will probably never happen.

Perhaps the thing I missed the most was the wonderful, peaceful, and focused feeling I have in my garden. The time I spent back there today helped jumpstart my creative visioning of the space; that part was dormant for the winter. This spring, I want to build a playhouse for my daughter. Last year I was concerned about the height of the branches of the purple plum tree that is over her play area. I have not taken a good look at the branches since before the leaves fell off, but today I did. Without the leaves I was able to distinguish the branch patterns and I realized some limbs I could easily remove that would open up the vertical height without sacrificing the coverage of the tree canopy; providing I ask the tree for permission first. I also evaluated the areas I still want to dig hugle-trenches in. Finally, I took a good look at the grasses and weeds that are sprouting and we came to a new understanding.

Last spring, between the time when I did not go to the PDC and when I visited the farm, I had gone to visit my family out of town. I was gone three weeks and when I got back, my garden had turned to a jungle of 18” tall plants. I gave them a haircut, but I did not remove them; I wanted to retain them for soil stability. I did not know what they were. This year, I will not be so hasty to cut them; I will identify them first because obviously they are pioneer plants. This year they are already sprouting and it seems there are even more than there was last year. I also did the same with the grasses; I cut them but left them.

When people saw my garden they thought I was crazy for all the weeds I left growing. I told them the weeds provided many functions. For one, the weeds shaded smaller plants that took longer to get going because the weeds were the first to sprout up. For two, they stabilized the soil and their shade cooled the soil. For three, many of them were dynamic accumulators and provided nutrients to the soil once they were cut down. Remember, my forest garden is on an abandoned organic garden plot that was plowed each year. The soil was loose, dusty, and I am sure it lacked nutrients.  This year, I am determined to identify each and every one of the volunteer herbaceous-layer plants and determine their function.

One area I was always hesitant about were the grasses. I had read many sources that said how bad grasses were because their shallow roots competed with trees. I tried a sheet mulch to get rid of them, but they were persistent. Finally, I gave in because they did help stabilize the damaged soil. This year, I want to get more cover crops going so I can use them as green manure. I also want to plant perennial covers of clover. I hope my comfrey grows big this year. This will be their second growing season; they were still small at the end of 2012 growing season but they were strong and resilient. I also want to plant some daffodil, onion, and garlic bulbs around the trees. I want all these plants to eventually crowd out the grasses. I am not going to pull up the grasses because of the important function they serve, but I want to plant other plants to take their place who can perhaps do a more complete job such as providing nutrients as well as soil stabilization and cooling. This is just my intuition that I do not want to wage war on nature. I know that many “know” permaculture, I might seem incredibly naive, lazy, and whimsical.

I wish to embark on a slight tangent at this moment. This last month my brother in law passed away from cancer. I have my own thoughts on cancer, death, life purpose, and the psychology of physical health, but this post is not the place to go into those philosophies. My brother in law was perhaps one of the most outspoken people about the untidiness and ugliness of my garden. He even went so far as to call all my work fruitless because I was following a pseudo-science. This statement deeply hurt me because he was insulting my baby, my garden, my partner. I do not believe death is meaningless, and despite our differences, I felt his passing gave me a gift. With his passing, this conversation about a pseudo-science came roaring back; emotions, physiological reactions, and everything else involved in that moment. I saw myself standing there and suddenly I was bigger and determined.  I saw myself continuing my forest garden, the learning, and the work. I saw what seemed like a future vision of my garden and my impact on the world by helping the method spread. His gift was to rile me up just enough that I would accept the challenge to educate people that permaculture and forest gardening were real and would help solve world hunger and lack. Thank you, my brother in law, for your amazing gift; you have reignited my courage in myself and this practice. I felt like I was faltering, stumbling, and starting to doubt if there was a point to my dabbling. Because of your wonderful display of doubt and insult, you have contributed to the healing of humanity and its apparent lack. Your love will ensure that more people will also feel the love. Thank you.

I will leave now, with a final thought about trusting myself. Last spring, my new apple tree, a three variety grafted one from Costco, blossomed. One of the branch’s blossoms turned to apples. The spindly, pencil-thick branch sported six baby apples. I was told by several people that I needed to remove those apples because they would break the branch. My husband was the only voice of dissent; he told me to leave them be. He said the tree had its own wisdom and he learned that from watching me follow my intuition in this garden. He said that the tree, in its wisdom, would decide if the apples were too much and it would drop its fruit. I was hesitant because six apples on such a small branch would be a lot of weight; but I let them be. I eagerly watched in trepid anticipation through the summer as the apples got bigger and bigger; the tree only dropped one apple. My husband and I observed a walnut tree branch that was growing into our part of the garden. We knew it was reaching for the peace of our place and wanted to be a part of it. He noted the wooden stilt supports on the branch and how they fooled the tree into thinking it was stronger than it was. We were also given the gift of witnessing a fruit laden branch break despite its wooden supports. It had over extended itself. The apple did not have supports and yet it was not showing any signs of distress. In the late summer, the apples were ready to pick because they slipped off of the tree with a slight twist of our hand. The apples ranged from 1” to 2” in diameter; they were small and not very tasty, but the point for this tree was not to produce tasty fruit but to prove that it could support fruit. I am very thankful for the chance to witness this display of plant wisdom and for my husband convincing me to listen to myself rather than the naysayers.



  

 

Forest Garden Year 3 (2012): Huggle-Trenches

Among my goals for the 2012 growing season, I wanted to put in some sort of water catchment. I love the idea of swales, but I was unable to find a resource on exactly how to do it; or at least none I could decipher.  A problem with swales, however, is I am not sure you can apply them to an existing garden without tearing it all up and starting over. My garden was done mostly on intuition and I did not spend time observing the land or researching proper plants and placement. Nonetheless, I am hesitant to dig up these plants because they are a part of me and we are evolving together. Another problem I heard is that swales are better suited to areas that do not have winter; I am not sure exactly where I heard this, but I believe it was from Paul Wheaton talking to either Geoff Lawton or Sepp Holtzer.

I decided I liked the idea of hugglekultur. However, I still had the same problem of it is best suited to a new landscape or gouged out area rather than an existing one. Another problem I have is I had a limited amount of sticks, no large tree trunks, and no extra soil. My dilemma then was how to apply huglekultur to an existing landscape using only sticks and without the assistance of extra soil. I wanted my trees to benefit from the huglekulture too. With these constraints, I came up with the idea of making a hugle-trench and digging it outside the drip line of my baby trees so that the roots can grow into the moistness.

I dug my trenches about 12" deep and averaging about 18" wide; some were narrower and some were wider depending upon the area I was digging. Below is one trench I dug.


 I filled these with sticks, some pencil thin, but most around 1-2" thick. In the trench I dug along the fence for wildflowers, I put in some branches about 6" thick. I also had a limited amount of 4" logs that I interspersed among my trenches. I did encounter some roots from some near-by, existing trees; I cut these roots and since they were mostly small, I do not think that will do any damage to the full-grown existing trees. Below is a trench with some sticks.


When the trenches had a good amount of sicks, I covered the sticks with the dirt, tamped the dirt by walking over it several times, and then thoroughly watered them. Below is a covered and watered-down trench.

 
 

The picture below is an updated graph of my garden space. My measurements were more accurate on this picture than the one before; on the first one I did alot of guess work assuming my space was square :/.  On this graph I show a rough estimate of the current crown of my trees; the first one showed what I expected their coverage to look like a few years from now. The brown areas show the trenches I dug. The pink dashes are stepping stones that line the edges of my beds, as shown above, or simply stones to walk on within beds.

Part 4 of 4: This Year's Goals and Pictures of My Garden


My plans for this summer are to make my keyhole beds more defined and to continue building them up with organic matter. To assist this I want to make more cement paver stones to finish out the outlining of the beds. I am excited to see how well my comfrey does and I am getting impatient to add it to my mulches. I also plan to buy some white clover for a general ground cover because it is low growing, tolerates cutting if need be, and is a good dynamic accumulator. I think it is important to add more garlic and onion and I want to get some marigolds going, which keep failing from seed, so I will probably buy some of these plants to get them going.  The marigolds, onions, and garlic will act as general pest detractors; I will keep my eye out for other odoriferous/strong smelling plants. I will keep researching about building soil fertility and may find some other plants I wish to add to aid in this effort. I also want to research nectary plants to act as an attractor for beneficial insects like lady bugs; insects that act as predators to other pest bugs like aphids. Another goal of mine, more long term, is to plant more items from direct seeding into the ground. Paul Wheaton also made a good argument about transplanting plants means the plants will not have a taproot because it is highly sensitive and is always killed in the transplanting process; I cannot remember the exact podcast but I am sure if you search the archives at the link for the soil health podcast then you can find it along with seeing all his other wealth of information.  Finally I want to figure out how to construct mini swales and integrate some huglekultur into my layout. I will keep you posted on how my garden develops. For now, here is an article that discusses hugle culture http://www.richsoil.com/hugelkultur/.

The picture below is a sketch of my L-shaped garden space. Each square represents 4 square feet or 2'x2'.  


The picture below is of the entrance to my garden. The purple plum with the green leafed plum and apricot growing underneath are in the foreground on the top, left corner. The middle section shows my makeshift arbor; a carport put up originally to serve as a greenhouse but I used as an arbor instead. On the right side of the arbor is the wire fence I attached for vining plants (grapes and kiwis will be trained up and accross and I want some others like peas or something on the fence). The paver stones are my primitive start to laying out key hole beds. As you can see the grasses and weeds are clipped low but are left to cover the bare dirt. At the end of the arbor is one of my volunteer trees (I believe is a plum). In the background behind the arbor but inside the fence are my volunteer trees: to the left are my other two volunteer trees, my apple is in the middle but hidden behind the volunteer tree under the arbor, and the peach on the right. Directly behind those trees and the fence is the grove of trees behind our property (some of those trees are cotton wood trees).


The next two pictures sort of show the plight of the stressed tree trying to reach the sun while the apricot has successfully reached it.



The next picture is a better view of my peach and apple trees with a back view of the arbor. The peach is on the left with a walnut tree touching it (apparently the walnut want to join this garden because he was 4' away last year) and the apple is on the right.


Part 3 of 4: Current Year, The Arbor, and Lessons From a Stressed Tree


Through the winter of 2011-12 I did lots of reading and planning. I started understanding a concept called key hole gardening so I restructured my beds to take that shape. I also realized that I needed to hold off on any other plantings and focus intently on building up the health of the soil. I also started learning about making swales; which I am still looking for a good resource on because I am missing something :).



I left to visit my family just prior to this year’s leafing out of the plants; when I came back three weeks later, I was pleasantly surprised. My peach and apple came back, my grapes came back, and my three mystery trees were lush and vibrant. Six of my eight comfrey plants I planted came up too. All of my strawberries made appearances. Even though nearly all of my mail order plants died and my cereal seeds never came up I still felt a great sense of accomplishment that my important plants, important to me that is, all made it through their first year and were happily establishing themselves.



This year, I took a more proactive approach to my weeds rather than the love/hate bipolar relationship I had before. I decided to trim them down as a general ground cover so I would not have bare soil rather than letting them rule until I had enough of them. This  approach of cutting them has been much more effective control than last year where I was trying to hoe them up. It seems my cutting them back is keeping them in check whereas hoeing seemed to encourage them. I am starting to understand a bit of information about succession and thus I have noticed that the variety of my weeds is slowly changing. The first year I had a ton of milkweed. The next year I had milkweed mixed with grasses. This year I have more grass and fewer milkweeds. I also have another weed which I am not sure what it is; but it provided good mulch. Like I said, the weeds are more manageable this year. This could be due to my perception shift of having them work for me rather than trying to have a love/hate bipolar relationship with them. This could also be due to maintenance on my part. It could be due to the land recognizing my intentions. I could be due to succession. It could be due to all of that or none of that, but the weeds are not as much of a problem.



I have made sure that my main plants are well clear of weed invasions that could choke them out. I am not too concerned with the weeds competing with the tree roots because many weeds have deep taproots which go much deeper than the shallow tree roots. I do know that the grasses may be competing, however, so my goal is to eventually have the beds so well mulched and properly planted that they are not a concern. I know they are nature’s attempt to start succession;  however, I want to control the direction of her succession in my garden and perhaps speed it up.



I still irrigate my plants because I have not built any water storage into the soil; like I said I am trying to figure out how to do that. I have noticed, though, that my plants need less irrigation and when I irrigate the water does not run off like it used to. This is not just my imagination. In the areas where I put the leaves this last fall, the water just soaks in; the areas that did not have the leaves the water quickly runs off. So I guess I am doing something right; increasing the soil fertility by giving it dead plant materials is helping increase the soil drainage. From what I understand then, I can deduce that I have probably increased the earth worm population through my mulch which in turn aerated the soil. During the winter I was also regularly adding my extra water kefir grains and their juice; I am not sure if or how that helped, but I was just following my intuition that perhaps they would add to the soil microbial level.



A surprise I was not expecting this year came from my trees: they set fruit. My one year old apple and peach both set fruit and so did my three mystery trees. It was hard for me to determine the identity of these mystery trees because I had the paradigm that they came from the roots of the grove of trees behind my house; it never entered my thought process that they came from the roots of some trees that were on the property. Last summer I finally figured out that they bore a strong resemblance to two trees I never took much notice of; two trees that I thought were both apricots that had been forced to grow under the canopy of a purple tree which I am told is a plum. I was also told that the two trees were different: one was an apricot and the other was a different variety of plum. I was not convinced because the two trees were nearly identical; or so I thought until I got better at observing them. When those trees set fruit this year I had my last piece of evidence to show me they were different and which one was the parent of my trees: they belonged to the green leafed plum tree. Their fruits were smooth and not fuzzy like the apricots (which had fruited before); so I guess they are plums. Their parent or the purple tree they grow under have never set fruit; this year both set a few fruits so this helped me in identifying the mystery trees.



Now that my observation skills have improved, I have set myself to assisting the highly stressed green-leafed plum; I believe it sent out its runners because of the stress. Unlike its partner the apricot, this tree had never reached the light. The apricot fruited because it was in the light; this one never fruited because no sun ever reached it. Whenever it sent out side branches it was immediately pruned. I took it over this year and kept those side branches and pruned out the top ones that were growing up into the purple-leafed plum in their vain attempt to reach some sun. I also tied a particularly long branch I found over to my arbor with the hope that if this branch was in the sun that it would encourage others to follow it too. I did this only four days ago, but I could swear that the tree looks fuller on the side and certain branches seem like they are taking more effort to reach for the sun. Another interesting event is that the apricot has found my arbor and has taken a fancy to it. Now my arbor that was originally for grapes and kiwis will now host apricots and plums growing over the top.



This is an interesting observation for me to illustrate an important concept in the canopy of the forest garden. From what I read, the trees should be placed in such a way that some sunlight is still able to penetrate to the garden floor. The edge of the forest, where it meets a field, is usually the most productive place of the entire forest; the interior of the forest is the least productive. While many plants do quite well in deep shade and many perennials grew up in forests originally, they were always more productive where they received dappled sun. The lesson that this tree showed me was that some sun is still important; I will keep this in mind so I do not plant too densely. I think this may be another reason that I have intuitively held off on getting more plants.



My comfrey are other plants I want to discuss. The comfrey plant that is the biggest is in dappled sun, but high shade. The next biggest one is near that area too. Both of these plants are in my arbor area for the grapes and kiwis. One grape is also growing in this dappled sun but once it grows up a bit it will be in full sun; just the floor is quite shaded. Four other comfrey plants emerged last week; two on each side of my peach, one by the apple, and the fourth in an area I was going to make a bed but later decided against so it is out in the middle of an area with no companions except the grasses. All four are in full sun and they seem to be struggling. Frankly I am surprised that they are still growing and preserving. I did not realize that they needed partial shade to grow so the full sun is probably quite taxing. The ones under the peach and the apple will eventually be shaded but their trees are still very young and quite sparse. I am interested to see what nature will do with these plants; if they will live or die or die back and come back when there is more shade. Next to the comfrey under the peach are some onions growing so this combination is probably greatly helping the fertility of the soil around the peach; I wonder if this will be enough to keep the peach pest free. I heard from Paul Wheaton in his latest podcast at http://www.richsoil.com/permaculture/1777-162-berms-and-cherry-tree-intervention/ that fertile soil, which leads to healthy plants, is enough to keep most pests away. Time will tell I guess. This little interaction along with how the comfreys develop should be interesting to observe. In part four, I wish to espouse some of my goals for this year and I also want to show you some pictures of what my garden currently looks like and a picture of a scale, but not exact, drawing I did showing the dimensions and the placements of my plants.

Part 2 of 4: 2011 Year Two The Garden Takes Shape


By the spring of 2011 I had compiled a large list of plants I wanted to put in my garden. I had read more on permaculture but I did not heed the advice to observe the land and sculpt it before putting in permanent plantings of perennials. I was too impatient and I wanted to grow my own food. As I was perusing for plants I quickly realized that organic, non-GMO, heirloom, etc were not only expensive but were hard to find. I made the decision that I could embark on that path little by little, but since what I really wanted was to get my forest garden going, I decided to temporarily put those standards on hold. Off to Costco, Home Depot, and mail order catalogues I went. At Costco I purchased a three in one grafted apple tree, a peach tree, and some blueberry bushes. At Home Depot I purchased a red grape, a green grape, and a raspberry. From the mail order I purchased cold-hardy kiwis, sweet pea perennial plants, two paw-paw, some honeysuckle vines, strawberries, and a few other plants. I did not have the knowledge to take starts of these plants nor did I have the resources of where to get those starts from in the first place. I was slightly concerned that my very inexperience would spell doom for these plants but I was too impatient. If these plants did die then I was out a small chunk of change; but I also realized I would have valuable experience.



I had my plants well before it was planting time in my area. I kept them in a dark shed but never the less they decided to prolifically leaf out. Concerned for their health because they were only in a bark medium, I made the decision to plant them even though I was concerned it was too cold. I dug holes, put in leaf debris and kitchen scraps in the bottom hopping they would give some nutrients, placed the plant, and filled with dirt. I did not amend the soil to proper conditions, I did not add fertilizer, I did not add mulch, I did not add sand to break up my clay soil, I did not test my soil density, I did not test soil ph, and I did not do what I was “supposed to do” when planting a plant. I only gave them was a leafy bottom to sit on. I was certain I spelled out their death sentence. I still did not understand that forest gardening was about purposeful manipulation of the environment to provide the best conditions for the plant. I thought forest gardening went in the opposite direction from traditional gardening with its focus on letting the plant fend for itself. I later realized that this fending was only done once all its needs had been met by the gardener. It was never supposed to be a sink or swim on its own ordeal.



Some of my plants died, particularly the mail order ones; however, most survived. My two grapes that I thought had died made a comeback this year. Once I got all these plants in the ground and delineated their actual beds with a border of cement paver stones I made a few years ago, I decided that my next step was to companion plant them. I began looking for companion plant lists and found several plants to add to my wish list for next spring. At this time I kept having a nagging idea that I needed to focus my efforts on building soil fertility. I began searching for dynamic accumulator plants. During this time I also began nurturing two other volunteer mystery trees that were identical to the first. I also took active steps to identify them.



For the fall I ordered comfrey roots and some cereal seeds buckwheat and rye that are supposed to be good cover crop plants. I decided that I wanted to cover the empty spaces with beneficial nutrient offering plants, also known as dynamic accumulators. Once the leaves fell from the trees I piled them up on my new beds. It was so nice to see my garden taking shape. In part three, I discuss the third and current year of my forest garden, I describe my arbor, and my lessons learned from a stressed plant.

Part 1 of 4: Beginnings of My Forest Garden


I have made allusions to the idea that I have a forest garden going and I posted my research paper that first motivated me to start forest gardening; yet, I have never actually described my garden. Here is my attempt to explain what I have going on, where my knowledge is currently, and some directions I want to head in. I split this into four parts. Part one is the first year I tried to implement some forest garden concepts. Part two is the second year where my efforts looked more like forest gardening with the planting of trees and plants that would serve as my backbone of sorts. Part three is my current year of tending my forest garden and the insights I have gained. Finally, in part 4 I listed my goals for this year and posted some pictures of my current garden.  



Two years ago in spring of 2010, I took over the management of an L-shaped garden space. This space was previously organically cultivated with typical row vegetables like corn, peppers, tomatoes, squash, etc. A few months prior to this time I had written my research paper on forest gardening so I was very excited to put into practice what I had learned… which as it turned out barely scratched the surface :).

                                                                                               

I cleared out a section of weeds and proceeded to seed in a 10’x10’ section of corn, sunflowers, beans, and squash. I was trying to grow the traditional three sister’s crop, corn, beans, and squash that I wrote about in my paper. I was also growing the sunflowers for their added shade and to experiment with a rapid, mini-upper story. Those plants were very brave… For the rest of the growing season they only received supplemental watering once a week and they had weeds knocking on their doorstep as constant companions. I was admonished to pull the weeds, but my newbie research led me to believe that all weeds were good, that they had just as much right to live as any cultivated plant, that they would help rather than harm, etc. I now realize that not all weeds are good, that it is ok to direct their growth habits, that they provide excellent mulch, and many other things about weeds; but I also admit that I have a lot of learning in this area.  As for the water thing, I was convinced that plants could live without supplemental watering… Little did I know that this is only true if I put time and effort into sculpting the land to hold the water. Ooops.



Well, by the time fall came I had a garden full of weeds, none of my plants could produce anything beyond some attempts at upward growth because they were so dehydrated, and my first attempt to forest garden was an utter flop. When the leaves began to drop from the trees and all the weeds died back I attempted to put down a kill mulch of several layers of newspaper; needless to say the wind had other ideas so it was a mulch that never was. I did, however, make my first real attempts to nurture some perennials. During the summer a strange tree started growing off to the side of my garden space. I was told to cut it down because it was one of “those pesky trees” that lived in a grove behind our house. I liked it and those trees as well. I said I was keeping it. I carefully wrapped its trunk in newspaper to officially mark it as my tree. I said it would be the upper story in my garden because it would reach 50’ or so if it were one from the grove behind our house. It did not occur to me until later that the upper story did not have reside in my small garden space. Just prior to the leaf drop I also rescued some baby trees from a grove of walnuts and peaches that was cultivated on an adjacent spot to my garden. I transplanted a walnut and two mystery trees. I also wrapped around their trunks at the base. With that I put my feeble attempt of a forest garden to bed for the winter. I am not a master gardener so I did not mulch or “cleanup” my space of dead debris. In part two I will discuss my 2011 planting year.

Forest Gardening: Feeding the World through Sustainability


Self-Responsibility Given Away

Near the beginning of recorded history Adam and Eve were expelled from the Garden of Eaten (Eden) . In Exodus 20:18 the people of Israel said to Moses, who had delivered them out of oppression in Egypt, “Speak to us yourself and we will listen. But do not have God speak to us or we will die.” This set a precedent where people decided that they were unable or unwilling to take self responsibility. In today’s world this is no more evident than the problems of world hunger and the resulting reliance on big business to feed the masses. The production of food requires intervention oriented cultivation which is unsustainable and exploits the environment. This dilemma and solution mimics the ancient Cahokia society as their exploitation of the land to feed their growing population ultimately led to disaster. Is this where present society is heading? Will the earth ultimately retaliate and spew natural disaster to destroy man-made infrastructure? “Climate change and the recent financial crisis clearly show that humans have entered an unprecedented era of fast and possibly dangerous changes” (Lichtfouse, Hamelin, Navarrete, Debaeke, & Henri, 2010). Entry back into the Garden of Eaten requires food production to epitomize the original conditions and for humanity to adopt awareness, responsibility, and motivation to change.

The Cahokia Mirror for Modern Agriculture

It is said that history repeats itself, unless the lesson is learned. In an eerie parallel to modern agriculture, the tale of the Cahokia Indians offers a prediction of doom if attitudes of exploitation do not change. Around 1000 AD The Cahokia Indians populated near what is known as St. Louis. It was the largest tribal settlement in the United States. Their population had grown so expansive that they had nearly eradicated wild animals to hunt. To feed the growing population, an agricultural system was established to grow maize; this system was very similar to modern monoculture. As the population grew and more maize was being grown, the Cahokia quickly overtaxed their stream’s capacities. Their solution was to divert water from a nearby stream into their water supply to create a river. For space to grow they practiced extensive clear cutting of the surrounding forests. This move served to increase maize production and population growth. However, this was not a sustainable enterprise.

“Eventually, disaster struck. Heavy storms which would have been soaked up by forest quickly ran off the agricultural fields, bloating the river, and causing floods and mudslides in the city of Cahokia. A subsequent earthquake was the last straw which broke Cahokia's back. Within a few hundred years of its inception, the city had dissolved back into the earth. The Indians fled the city and developed a more sustainable agricultural system based on small fields of maize surrounded by managed forests of fruit and nuts. ” (Ana & Mark, 2010, Cahokia: a cautionary tale).

Modern Agriculture: History Problems Repeated

It took over 1600 years for human population to reach 1 billion people and it took scantly 400 years for the population to increase 6 fold to 6 billion people. Currently the population has increased by nearly 1 million people in less than 11 years. While the population growth is showing signs of slowing, the rate of growth is so large that current agricultural production cannot keep up with the demand. “Currently, the World Health Organization estimates that more than 3 billion people worldwide – the greatest number in history - are malnourished” (Berg & Hager, 2007, p. 338). To increase food yields farmers have turned to science to create super-producing crops. While this has met much of the population growth, it is also unsustainable, therefore this high intensity food production cannot continue for more than a few decades (Berg & Hager, 2007). What then? How will the growing population be fed?

Modern farming methods involve monoculture, or long rows of one type of food. To feed the growing population science intervened in plant production through genetic manipulation to increase food yield. These crops require massive interventions such as pesticides, high potency fertilizers, herbicides to discourage unwanted weeds, and special machinery to sustain the food through the growing season and onto harvesting. (Berg & Hager, 2007). Pesticides are used in increasing amounts to deal with the out of control pest populations which monoculture encourages. A monoculture is considered a feast to invader bugs, thus their exploding populations require even more pesticides (Agroforestry Research, 2008). All of these things contribute to pollution by poisoning the plants, animals, and people in the environment. “…Agricultural practices are the single largest cause of surface-water pollution…” (Berg & Hager, 2007, p. 346).

The terrestrial resources needed to sustain such large operations are tremendous. Aquifers, rivers and streams are rapidly becoming depleted from the large amounts of water used to irrigate these high yielding crops. Immense tracts of land are needed to meet current and future production demands. However, all the cultivatable land in the world is already taken and that land is giving way to urban development. Wild animal populations are also becoming increasingly isolated as more land is wrest from forest through clear cutting. Clear cutting contributes to soil erosion and floods because there are no longer natural vegetation roots to hold the soil in place or absorb large amounts of water from rain (Berg & Hager, 2007). Soil erosion also occurs when land is tilled. Tilling disturbs the natural ecosystem of the soil killing much of the microbiology and soil structure (Ana & Mark, 2010).

To offer a complete picture, the economics of such large scale farming also need to be accounted for. It takes huge sources of capital to live in such odds with the environment. Nature will eventually reclaim what it loses thus efforts to keep nature away are expensive. “It seems apparent that continued reliance on monocultures is more of a liability than an asset.” (Agroforestry Research, 2008, p. 6). It would also seem that such huge amounts of work and investment for such limited, or unbalanced food return does not make economic sense. Natural disasters must also be taken into account. The old adage about “don’t put all your eggs in one basket” applies to reliance on one huge mono-crop; putting that principle to the test. The Cahokia found their solution in gentle land persuasion, otherwise known as forest gardening. Will modern society embrace their lesson or will history repeat itself?

Forest Gardening: An Ancient Practice

Researcher Charles Mann (2006) delineates an alternative view of the history of American Indian land influence. American History teaches that the, “American Indians had a pure connection with the nearly untouched wilderness they lived in” (Anna & Mark, 2010, What American Indians can teach us about permaculture). Mann’s research has shown otherwise stating that the American Indians had significant influence on the structure of the forests and in created large civilizations sustained by agriculture which covered nearly two thirds of the United States (Mann, 2006).

The tropical rainforests of South and Central America have long been considered virgin forests. The Amazon forest and Mayan forest rank first and second, respectively, for sheer amount of biodiversity present in one place; in other words they have higher species diversity than anywhere else in the world. Scientists have long considered the forests to be an anomaly of nature. Evidence now points to the contrary. Because over 90% of the plants are useful to humans, science concludes that much, “8% to 100%, [of the forest] was anthropogenic” (Ann & Mark, 2010, Anthropogenic forests in the Amazon), or created through carful, human manipulation, see figure 1. To add credence to the argument, forest stewards of the El Piliar Maya Forest Garden Network [El Pilar] (2009) state that “that there is a higher percentage of useful plants in forested areas where the Maya lived than forest where people did not live. This suggests that the Maya manipulated their forest, favoring plants that were useful to them, changing the composition of the forest.”

Clarifying Terms

Forest gardening has become a blanket term for any system which involves the careful manipulation of plants in a forest setting to produce the maximum amount of beneficial plants. That said, there must be a distinction between temperate forest gardening and tropical forest gardening. Technically any gardening which takes place in the tropics is called permaculture. However, these techniques will not work in temperate forests. Robert Hart invented forest gardening as a way to apply the wisdom of permaculturists to the lack of abundant rainfall, less direct sunlight, and seasonal fluctuations of a temperate forest (Ana & Mark, 2010). That said the terms are usually used interchangeably. One thing is certain however, “Once a forest is managed it becomes a garden” (El Piliar, 2009, How a forest garden is different from a plowed field).

The Forest Garden: A Modern Garden of Eaten?

In the Garden of Eaten all was perfect and food was abundant. Adam and Eve had no cares except to be good stewards of the garden eat their fill. They did not have to toil for their food; they only had to pick it. When temptation overtook and they ate from the Tree of Knowledge, the couple forsook the wisdom that partners with knowledge. In so doing they went against nature’s harmony and balance; choosing to follow self-righteousness and abdicating spiritual understanding. They no longer sought direct sustenance rather they chose to eat by the sweat of their brow. They were expelled from the abundant food provision of the Garden to toil away in unfulfilling, meager agriculture that would never cultivate anything resembling that abundance.

Forest gardens, once established, require little human intervention and do not deplete or harm natural resources the way monoculture does. Plants are introduced to take maximum advantage of natural rainfall. Land is not tilled and plants are not removed so soil structures remain intact. Many plants are perennials thus they do not need to be replanted year after year and they contribute to soil health. Even the annuals are encouraged to reseed themselves. Some plants, known as dynamic accumulators and nitrogen fixers, enrich the soil naturally without the use of fertilizers.

Guilds or groups of plants which cohabitate nicely, are created for maximum land efficiency and production. Considerations for finding good cohabitatable plants include: root depth, spread, and type; plant size and spread; mineral, water, and light needs; and growth season. These guilds can then can then provide all their own needs as well as help their neighbors. Pesticides are not used because plants are also grouped so that one plant discourages the pests of another. Herbicides to kill weeds are not used because the plant groupings are so dense that weeds cannot gain a foothold. When the gardener marries vegetation by filling in empty niches with useful plants he or she expands Mother Nature’s plan. Together they co-create a garden of super abundance (Agroforestry Research, 2009; Ana & Mark, 2010).

This guild process creates a system of over yielding which can be further explained by a physicist Eliyahu Goldratt (AGI – Goldratt Institute, 2009). Goldratt applies the principles of physics to management philosophies in a system he called the Theory of Constraints. This, in turn, can be applied to the management of land. A constraint is a limitation. For a farmer, his or her constraint is the land. This constraint limits the production capabilities of the farmer since he or she views the land as having a limited yield. A farmer in this situation accepts this as inevitable and the solution is to find more land or accept their financial cap. More land is not a feasible solution, however, as is discussed earlier. Goldratt would admonish that one has to maximize the potential of the constraint. A forest gardener does just that; growing more in less area; or increasing the land’s efficiency and output.

An example to showcase a guild’s high degree of productivity and beneficial cohabitation is found in the traditional three sisters crop: beans, corn, and squash. Researcher Stephen Gliessman noted that corn production, when grown in the three sister crop nearly doubled under these conditions and the bean and squash yields remained relatively the same as in conventional monoculture. But that is not the whole story. The bean and squash yields may have been the same, however all this was grown in an area less than half the size of the land it would take to grow these same plants as monocultures. He said, “This is known as over yielding. Considering increasing hunger and starvation, this more productive model offers hope for a better future” (Agroforestry Research, 2008, p.5). As far as beneficial cohabitation: the corn stalks provide a vertical surface for the beans to climb upon; the beans gather and share nitrogen because they are known as nitrogen fixers; and the squash grows so thickly as to effectively block out weeds (Agroforestry Research, 2008).

A nitrogen fixer means the plant has a unique root system which can convert otherwise inert nitrogen into beneficial nitrogen. Dynamic accumulators are also used in beneficial groupings because their deep root systems mine minerals from deep soil depths to store in their leaves. Plants are also considered dynamic accumulators if they provide a good home for beneficial bacteria to colonize. The soil benefits of both nitrogen fixers and dynamic accumulators are usually realized as the leaves of these plants are used for compost. (Ana & Mark, 2010).

Forest gardens take agricultural practices to a new level of sustainability while affording high yielding, and highly nutritious food. The sheer diversity of useful plant material grown in such a small area is economical. “A greater diversity in one’s diet leads to better nutrition and health… [M]alnutrition results from…a reliance on a limited number of foods, which generally have lower nutritional value… (Agroforestry Research, 2009, p. 8)” Promoting home gardening in a system of large diversity goes a long way to discouraging malnutrition. Heriberto Cocom, master forest gardener for El Pilar (2009), states that everyone has some land they can garden on; therefore, everyone can plant a forest garden. Plus, if one does not have land, community gardens are always options especially since the large food yields lend themselves well to sharing. Nutritional density also reduces malnutrition. The density is higher in the perennial versions of typical annual plants like spinach and its perennial counterpart good King Henry. Since forest gardens rely on perennials they naturally produce more nutrient density. In addition, the cohabitation and resource sharing of the plants provides higher nutrient density than monocropped plants (Agroforestry Research, 2009).

Forest gardens make more economic sense. A diverse range of plants can be grown in an area a fraction of the size needed for monoculture. This diversity has the added benefit of economic security. Should a natural phenomena like blight attack one crop the others are still intact. Conventional farmers, relying on one crop, would be devastated by the blight (Agroforestry Research, 2009). Polyculture, the cohabitation of many plants, also allows the farmer to grow year round as opposed to just one season. This additional growing time is beneficial for the pocketbook (El Pilar, 2009). A temperate forest example of this is highlighted by Agroforestry Research (2009) when the author discusses harvesting fresh food for his winter dinner party. Finally, a forest garden makes economic sense because of the diversity of cash brining crops. A forest garden, “produc[es] plants to meet a diverse array of human needs, like food, shelter, medicine, and many others” (El Pilar, 2009). Plants like the bamboo plant can also be used for clothing.

The best example of a city sustained on personal forest gardens is found in Kerala, India. Agroforestry Research summarizes forest gardening founder Robert Heart’s book Forest Gardening: Cultivating an Edible Landscape. “Hart’s book cites the 3.5 million home gardens in Kerala, India that provide the majority of food for the 32 million residents in an area the size of Switzerland. Kerala ranks second in The Physical Quality of Living Index for Asia despite being one of the most populous places on Earth and having an average income of less than $400 per year. Only Japan ranks higher. Life expectancy rivals the US, literacy rates are approaching 100%, free hospitals and Ayurvedic clinics are very common, and ninety percent of the Keralese population owns land. Their secret is that they don’t need that much money--practically all of their necessities are growing in the backyard” (2009, p.4)

Forest gardening is a community affair, thus much of the labor is voluntary. A community forest garden would follow the same rules and regulations of a regular community garden. A community garden requires that those community member who wish to benefit from the harvest need to contribute to the upkeep of the garden. A forest garden is self sustained and thus does not involve all the work a regular community monoculture garden requires. It only requires regular pruning and mulching with most of the work occurring at harvest time. It seems reasonable that each community member would harvest their own food. This is the same principle that God set forth in Exodus with the manna. The manna was provided each morning and each member of the community was responsible for acquiring what he or she needed for the day. El Pilar (2009) discusses community involvement is essential for a source of labor and generational knowledge acquisition. This not only keeps money in the community rather than outsourcing for labor, but it allows for greater camaraderie. In addition the garden is, “is almost entirely maintained with local resources, such as household refuse (compost), organic material (dead weeds), ashes from kitchen fires, and manure,” providing all the necessary fertilizer to “enrich the soil” (El Pilar, 2009, What is a forest garden?).

Problems Facing Adoption

People have abdicated their rights to produce their own food to the big business farmer. Forest gardening, despite its benefits, is unlikely to be adopted as a serious alternative by farmers until some biases are dispelled. For one thing forest gardening is a long term proposition not a fix-it-quick scheme; big problems require big solutions. These solutions must be far reaching with true commitment. In a business text book called Wharton on Decision Making (Hoch, Kunreuther, & Gunther, 2001, Ch. 6). the authors describe “Maintaining a normal state of mind requires constant practice.” To further describe this idea they quote from a book named The Book of Five Rings by an author named Musashi, “This is something that requires thorough examination, with a thousand days of practice for training and ten thousand days of practice for refinement” (p.114) They further explained that: “To the ancient Chinese, reflection was closely linked to knowledge. Because the Chinese believe all things are interdependent, knowledge was the ability to trace out the connections between things. Once this was accomplished, the decision maker would know what actions to take today to reap the benefits of the future. The idea was summarized in a saying, ‘To know after seeing is not worthy of being called knowing’” (2001, Ch. 6, p.109).

This concept can be applied to the creation of a forest garden. A forest garden can take up to 10 years to reach maturity; therefore it is not a one season solution like a monoculture. It requires patience. Knowledge acquisition of the land, climate, whether patterns, rain fall, plant characteristics, plant interactions, plants needs, plant cohabitation options, etc. all require patience and commitment. In other words, farmers as businesses people are looking for short term profits, not long term gain. The farmer would justify his or her position saying they are concerned with the bottom line, profits. Mechanized crop harvesting is cheaper than the human labor necessary to harvest food in a forest garden. This translates to fewer profits.

This is a fallacy however. The adoption of the forest garden method of cultivation requires a paradigm shift. It also means that the two systems cannot be fairly compared because they are so different. Sure, the farmer may profit more from mechanized harvesting systems, but the farmer is not looking at the other factors involved; this is narrow minded thinking. The farmer automatically saves money because he or she does not need to spend money on pesticides, herbicides, special machinery, fossil fuels, machine upkeep, fertilizers, new batches of seeds, etc. In addition the costs to the environment of monoculture are not taken into account in this statement. That said, many farmers, particularly those in third world countries are not concerned with environmental preservation if it cuts into their profitability (El Pilar, 2009; Ana & Mark, 2010; and Berg & Hager, 2007).

This narrow minded thinking is based out of fear of the unknown. Fear is an interesting concept as an acronym for False Evidence Appearing Real (author unknown). The Bible further explains this concept in Hose 4:6 when it states, “My people are destroyed from a lack of knowledge.” The idea behind this is fear is often illogically justified by strong emotions not logical evidence. The farmer in this case, would base his argument for maintaining modern agricultural methods on the illogical evidence of the strong emotion of fear. The overwhelming benefit of forest gardening would be lost on him or her.

For the sake of logic, the fear of the farmer is also perpetuated by the biases and discrimination from the farmer’s suppliers that exist against sustainable agriculture. For example, insurance agencies often will not insure a sustainably farmed crop because they consider it too high risk (Bailey & Preston, n.d.). Once again this bias is bases upon fear. An example of discrimination against forest gardeners is in Brazil where the government considers an area to be developed if it is monocropped. Forest land is considered undeveloped and therefore subject to economic pressures to “develop it” (El Pilar, 2009).

Gary Yukl (2006), another business textbook author, provides an explanation of modern managers that provides a striking similarity to the farmer whose motivation is profit. Most people have the misconception that managers have inordinate amounts of time to sit in their offices and create elaborate action plans. This is simply untrue. Managers, he says are involved in a flurry of activities all day long as they run from place to place putting out fires; they react not act on their situation. Their processes are fragmented and their activities lack any real cohesion. They only look at the steps involved at this particular moment and lack a view of the bigger picture of the interaction of things. Likewise farmers do not have an overview of the bigger picture and their processes are thus fragmented.

Perhaps the biggest difference between the forest garden and modern agriculture is the forest garden is not really suited to big business per say. To understand this further, two principles that seem unrelated, warrant introduction. Christine Woodrow and Frances Press, university professors, discussed a concept that is similar to the dilemma of the modern farmer even though they were discussing the dilemma of the child in daycare. “At the turn of the 21st century [people] have been witness to an acceleration of privatization and commercialism in many aspects of everyday life” (2007, p. 315). They further discussed “that values such as trust, respect, good will, sincerity and fairness…are likely to be transformed [into] supplier-consumer relationships built upon profit motives” (2007, p. 318

To further explain that dilemma the views of another pair of professors, Genevive Vaughan and Elia Estola, also discussing education, can be applied. They proposed that two paradigms exist that rule all human engagements. The dominate paradigm is the exchange paradigm where recompense is expected for any service given. This is the paradigm that dominates world commerce and relegates those goods which satisfy human needs, like food, water, shelter, education, etc. to vehicles for exchange rather than nature’s free provision. On the other hand, a paradigm that has just as much to offer, but is only recognized as the domain of mothers to their children, it the gift paradigm. In the gift paradigm, goods and services are offered out of love and respect without expectation of a payment in return. This paradigm is long term whereas the exchange paradigm is short term. For example, mothers tirelessly offer their services and never once do they ask their children for payment. The reason is because the mother’s intuitive wisdom knows that the better the rearing in the present, the better adults their children will become (2007). She knows that someday the fruits of her efforts will manifest or the seeds will flourish.

The gift paradigm relates to the forest garden in once it planted and nurtured to maturity, it freely gives what it has without expectation for recompense. A monocrop may give its harvest but that only happens in exchange for tremendous amounts of interventions and constant vigilance from the farmer. As stated before, the return of the crop is disproportionate to the amount of work involved in getting that return. Because a monocrop cannot give, the farmer does not understand the gift paradigm, thus, these two principles adequately explain the dilemma of the farmer. Farmers have to be responsible to big business which overtakes precedence for what is right. The farmer is driven by the exchange paradigm because that is the dominating force of our world. The farmer will never realize the gift paradigm because it does not follow what he or she has always known.

The gift paradigm also describes Eliyahu Goldratt’s (AGI – Goldratt Institute, 2009) Theory of Constraints when he states that one needs to maximize their constraint. The farmer does not believe his constraint can be maximized. However if he or she were to look at the land as providing a free gift, then that gift paradigm would naturally lend itself to the creation of the forest garden to maximize the constraint of the land. The farmer is blinded by ghosts of profits, rather than looking at the entire picture of expenses. Forest gardening will never be a feasible solution when it is viewed completely through the lens of big business, or exchange paradigm, and thus meddling in the realization of the forest garden or gift paradigm.

Despite showing the illogical nature of the farmer’s for profit argument, the farmer would not be compelled to change his or her mind; they have no reason to. They do not see their system as broken or if they do they are too afraid to take action to fix it. A logical way of looking at all sides of the issue and eliminating the fear, described later, would be to examine John Nash’s Theory of Equilibrium (Osborne, 2002). This theory states that in every game there is a win-win situation, not always a win-lose. This theory when applied to the farmer, would state that what is best for the farmer is for maximum land usage and what is best for the people is to have abundance of food. If food production followed forest gardening, it would overcome the World Health Organization’s prediction that agriculture will quickly become inadequate to supply the demands of the people.

Re-entering The Garden of Eaten

The lesson of the Cahokia basically states if one cannot learn from past mistakes or perceive current misdirection, then one cannot progress toward finding a solution. The Bible explains this differently in John 20:29 when it states, “Blessed are those who have not seen and yet have believed” and in Hosea 4:6, “My people are destroyed for a lack of knowledge”. Exploitation of the land, also known as monoculture, is not a solution for feeding the masses. Exploitation and crop isolation will ultimately lead to a disaster because it does not work with the ecosystem.

Forest Gardening is the art of resisting exploitation as a solution and relying on an intuitive process which draws upon the knowledge of interactions to follow nature’s way. The gift paradigm explains the concept of the forest gardening as the plentiful giving of food without expectation for recompense. Modern agriculture is based on the opposite exchange paradigm. The monocrop does not give freely rather it does so in exchange for the farmer’s intensive interventions.

The Theory of Constraints delineates that the farmer’s land is his or her constraint, meaning that it can only produce so much. The theory also discusses that one must seek to make the constraint achieve maximum profitability. The farmer’s paradigm will not support more yield from the land, however, the polyculturist recognizes the untapped potential land yield through successful plant cohabitation. The Theory of Equilibrium provides the solution stating that the best solution would be something that best provides for the farmer’s and the people’s needs, or win-win. Monoculture, while trying to have the farmer’s best interests in mind, is illogical in nature and is also a win-lose proposition. Forest gardening represents mankind’s journey coming full circle; from original sin to re-entering the Garden of Eaten.
