Permaculture advises: growing a minimalist garden (that requires the least amount of work!)

If you are those kind of people that prefer to start the garden and then do nothing, this is for you.
This is a list of plants to make a permaculture edible garden, made of perennials, that once you start, there is almost no further work required. Some vegetables are perennials, other are self-seeders.


Some plants for a minimalist garden:

Perennials for greens (spacing indicated)

  • 9-star broccoli .... 100cm
  • Daubenton's kale ... 60 cm
  • Good king henry (bitter taste) .... 30 cm
  • Sea beet (tolerates sandy soils) .... 30 cm
  • Tree collards .... 100 cm
  • Skirret .... 25 cm
  • Sea kale .... 90 cm
Perennials for salad use
  • Ḿitsuba (can grow in part shadow) .... 15 cm
  • Musk mallow .... 30 cm
  • Pink purslane (acid soil, and shadow) ... 15 cm
  • Salad burnet (alkaline soil) .... 20 cm
  • Chicory .... 20 cm
  • Garlic cress ... 30 cm
  • Ramsons or wild garlic (for shadow) ... 10 cm
  • Sorrel ... 25 cm
  • Turkish rocket ... 50 cm
  • Watercress ... 15 cm
  • Everlasting onions ... 15 cm
  • Tree onions .... 20 cm
  • Welsh onions .... 20 cm

Perennial 9-star broccoli, can give many crops if you keep cutting them.
Self-seeders for greens

  • Fat hen 
  • Swiss chard ... 25 cm 
  • Alexanders .... 50 cm
Self-seeders for salad use 
  • Chickweed (can grow in part shadow) ... grow without thinning
  • Lamb's lettuce ... 10 cm
  • Winter purslane (tolerates sandy soils) ... 15 cm
  • Bittercress ... 10 cm
  • Land cress ... 15 cm
  • Nasturtium ... 15-20cm
  • Rocket ... 10 cm

The following table can help you calculate how many plants do you need to get full ground cover with perennials. The recommended spacing is described later below.

Spacing, cm ---- Plants
100 ................... 1
60 ..................... 3
30 ..................... 11
25 ..................... 16
20 ..................... 25
15 ..................... 44
10 .................... 100

Biointensive (organic) agriculture

John Jeavons, one organic agricultor has designed years ago, a system of intensive biodynamic farming that produced yields of food around several-fold larger than conventional farms! We can feed ourselves in a much small space, nearly 40 per 40 square meter, and leave three quarters of similar land for wild nature and animals.

"This miniaturization of agriculture is not new. Small-scale sustainable agriculture has supported such widely dispersed civilizations as the Chinese 4,000 years ago, and the Mayans, South Americans, and Greeks 2,000 years ago.
Ecology Action has dedicated almost a quarter-century to rediscovering the scientific principles that underlie these traditional systems. The people in Biosphere II in Arizona have been using techniques based on those outlined by Ecology Action: they raised 80 percent of their food for two years within a "closed system." Their experience demonstrates that a complete year's diet for one person can be raised on the equivalent of 3,403 square feet!"

"This is an improvement over traditional Chinese practices, which required 5,000 to 7,200 square feet. In contrast, it takes commercial agriculture 22,000 to 42,000 square feet to grow all the food for one person for one year, while bringing in large inputs from other areas. At the same time, commercial agricultural practices are causing the loss of approximately six pounds of soil for each pound of food produced.
Biointensive mini-farming techniques make it possible to grow food using 99 percent less energy in all forms - human and mechanical, 66 percent to 88 percent less water, and 50 percent to 100 percent less fertilizer, compared to commercial agriculture. They also produce two to six times more food and build the soil."


Strawberries grown in a city balcony; tasty harvest!
HOW MUCH LAND DO WE NEED TO FEED OURSELVES, OVER A YEAR:

This is, 32 meters x 32 meters for a property to cleverly produce all our necessary food (1 person for a year!) or around 1000m2 (a quarter of an acre, a tenth of hectare).
In chinese practices 42 x42 meters is necessary for producing food for feeding a person over one year (around 1800m2 or half an acre). Conventional agriculture needs around one hectare, 10000m2 or 100m x 100m).



The Biointensive Method

"The basics of this whole-system approach can be summarized as follows:
Most life in nature occurs at the interface of soil, water, air and sun. Biointensive soil preparation practices create growing beds with more surface area to maximize the effect of nature's life processes. Double-dug beds, with soil loosened to a depth of 24 inches, aerate the soil, facilitate root growth, and improve water retention. The health and vigor of the soil are maintained through the use of compost. Close seeding spacing is used to protect the soil microorganisms, reduce water loss, and maximize yields. Companion planting facilitates the optimal use of nutrients, light and water, encourages beneficial insects and creates a vibrant mini-ecosystem within the garden. The use of open-pollinated seeds helps to preserve genetic diversity and enables gardeners to develop their own acclimatized cultivars.

A focus on the production of calories for the gardener and carbon for the soil ensures that both the gardener and the soil will be adequately fed and that the farm will be sustainable.
How can the soil's nutrient fertility be preserved with agriculture continuously removing nutrients as one crop is harvested after another? One answer is surprising. Each person's urine and manure contain approximately enough nutrients to produce enough food to feed that person. However, those nutrients are not enough when they are spread thinly over the one-half to one acre that it takes mechanized commercial agriculture to produce that person's food.
Biointensive mini-farms require much less area to produce the same yield of crops, so the nutrients contained in one person's wastes can be applied in a more concentrated way. This enables the nutrients to be fully effective, and high yields can result.

Because of this higher productivity, Biointensive practices could allow one-half to three-quarters of the world to be left in wild for the preservation of plant and animal diversity.
It has been said that Biointensive practices might make it possible to grow food for all the people in the US in just the area now used for lawns. This possibility could mean thriving agriculturally self-reliant cities with 'green belts' to produce all their food."

The same results are obtained in calculations from other people, by practical experience:
http://thesietch.org/mysietch/greenspree/2007/07/17/self-sufficiency/ 0.1-0.4 acre per person or 4-people family

That would be roughly 30-40 meters per 30-4o meters square land in a property.
We could grow about 10 main cultures in ten 10x10m squares, which would give our 30x30m big square


This is a one-acre square of land for most food self-sufficiency.

These garlic were grown in a city balcony and close to each other, in a small container

However when considering water catchment, compost and grey water treatment, solar and wind energy, wood for fuel, possibly goats for milk, one should have at least 3-5 acres, which is roughly 10 times the size for plant-based food self-sufficiency.

I think a square of quarter-acre for vegetable production (as suggested), plus another quarter-acre for an house and energy/water facilities, plus another two quarter-acres for one orchard and a wildlife forest garden and a goat place, that give a good one acre for self-sufficiency.


Please check our drawing for a self-sufficiency property:






One common mistake is expecting too much land for self-sufficiency.
Our tenth of our quarter-acre is enough for producing potatoes for a year for a couple.
Another mistake is to expect 100% self-sufficiency. Neither is desirable neither humanly possible. Some food is still very cheap. It is more desirable by promoting local shares of different self-sufficiency families to create the necessary abundance of food for everyone.

The Green Spot has returned!! This time, in Iceland!

And after one year after without gardening, we finally manage to live in a place with a garden space, this time in Iceland, at the ecovillage Sólheimar, where we presently happily live and work.


We have a heated greenhouse-like balcony, facing south, and a small space in front of the house. In just 3 weeks, we started from zero and we are growing now about 150 pots with flowers and vegetables!


I just brought all my seeds, and sown them in eight trays. The temperature indoors is around 22ºC, due to Icelandic geothermal house heating, which makes it perfect for growing vegetables inside.


We reuse hundreds of plastic cups, and also yogurt trays, to where we transplant the tiny seedlings, and while we wait that the weather warms outside (it still snows). This is practical, free and environmental friendly!


The list counts with tomatoes, sweet peppers, eggplant, courgette, oriental salads, lettuce, rucula, spinach, chicory, beets, swiss chard, broccoli, kale, kohl-rabi, celery and celeriac, peas, ginger, several mixes of butterfly and wild flowers, aromatic herbs, and some permaculture rarities such as perennial broccoli ("9 star") or the strawberry spinach (chenopodium capitatum). Below, we show some oriental vegetables such as  pak choi, mizuna, tatsoi or komatsuna spinach, ideal for stir-fry.


We are also attempting to establish some perennial flowers outdoors, such as anemones, ranunculus, dicentra, astilbe and day-lilies. I sown poppies, aquilegea,. campanula, delphinum and nicantra physaloides. And I am trying to grow also allium ursinum, atriplex, jerusalem artichokes, scorzonera, salsify, purple carrots and black potatoes. I have sown some of these indoords, in a dish with wet paper, to see if I could sprout them faster, for later transplanting, when the danger of frosts has passed.


This is a true challenge of Permaculture in polar climates! The weather is still cold and windy. Finally, we wish we could improve our food self-sufficiency, and create in this polar landscape, some color and biodiversity. Let's see how this green experience will run!

Important influences to Organic Farming, Permaculture, Self-sufficiency and Environmentalism


Henry David Thoreau (USA, 1817-1862)

"Live at home like a traveler"


T
horeau was an American philosopher, poet, historian and naturalist. Thoreau is best known for his book Walden, a reflection in simple living in a natural environment, and self-sufficiency in the woods. Walden is a declaration of independence, self-reliance and spiritual discovery. Thoreau describes his two year stay in a cabbine, in a forest on a edge of a town, living a simplified life, and discussing his needs of shelter, food, clothing and money.
Thoreau was a leading Transcentalist philosopher, with a core belief that there is a spiritual state that transcends physical reality and can only be realized through the invidual's intuition rather than religious doctrines. He was also one of the founders of modern Ecology and the environmentalist movement, studying the growing patterns in fields and woodlots. He was also greatly interested in the accounts of travellers of that time, such as Cook, Magellan and Darwin.
Thoreau is also well known to have introduced Civil Disobedience as a method of non-violent protest and resistance, that later influenced Gandhi and Martin Luther King.
During a time of a great industrial revolution and urbanization, Thoreau was one of the first ones to call for a return to nature, and to a more simplified, liberating and natural way of living.


Rudolf Steiner (Austria, 1861-1925)
“A healthy social life is found only, when in the mirror of each soul the whole community finds its reflection, and when in the whole community the virtue of each one is living”


Steiner was an Austrian philosopher, social thinker, architect and esotericist. He founded the spiritual movement of Anthrosophy, which is a continuation of the European Transcendentalism. Steiner attempted to find a synthesis between science and mysticism. He provided a bridge between the cognitive thinking of western civilization with the inner and spiritual needs of the human being. He created a revolution in many fields, such as architecture and visual arts, performing arts, (Waldorf) education, medicine and also agriculture.
Steiner invented the concept of biodynamic farming and gardening, which is one of the first sustainable forms of agriculture. He was concerned about the impact of chemical agriculture on the environment and the loss of nutrients on the soil. Steiner encouraged organic practices such as the use of manure, composting, and achieving the right balance between the different species of plants and animals on a farm. He stated that the use of chemicals on agriculture was very detrimental. He also analysed the spiritual energies underlying the growth of plants, influenced by the planets, and the life energy elements on the soil, which were recorded in a serie of his lectures. This marks not only a natural approach to agriculture, but also a spiritual and hollistic one, where all the life forms are respected and in the proper balance.

Sir Albert Hobert (UK, 1873-1947)
"The health of soil, plant, animal and man is one and indivisible"

Hobert was a Botanist and considered the father of organic farming. He travelled to India to teach western conventional farming but came convinced about the importance of healthy organic and natural practices of farming to the health of local populations.


Masanobu Fukuoka (Japan, 1913-2008)
"If we throw mother nature out the window, she comes back in the door with a pitchfork."


Fukuoka was trained as a microbiologist and a soil and plant scientist. At the age of 25 he began (like me) to doubt the wisdom of modern agricultural science. He eventually quit his job after having a moment of great insight in one night, returned to his family farm and developed a pioneering no-till form of organic agriculture. Although he practiced organic agriculture, he took a step farther in not only growing without any pesticides, herbicides, but also without any significant weeding or tilling.
Fukuoka asserted that there is a great difference between organic farming and natural farming; in that organic farming was still scientific in approach like conventional farming, and could still damage the environment. Fukuoka wished to reproduce natural conditions as close as possible. He emphasizes on mainting diversity. On his method with no plowing, the seeds germinated when the provided conditions were right. Ground covers of clover provided nitrogen; weeds considered part of the ecosystem but periodically cut (not weeded) to allow the nutrients to return to the soil without disturbing it; the crops are grown one after the other, but the ground is always covered (therefore allowing the retention of humidity and life beneath it); straw is used as mulching. He detailed his findings in his famous book "The one-straw revolution".
Fukuoka was also a pioneer in the development of seed balls: the seeds are mixed with clay, water and compost and thrown into the soil, allowing germination without tilling.


John Seymour (UK, 1914-2004)

Seymour was a leading figure of the self-sufficiency movement during the sixties and seventies. At the age of 20, he went to South Africa and live through a sucession of jobs. There, we also contacted with the self-reliant life of bushmen tribes, where we spend some time and created a friendship with them, and learn about their life as hunter-gatherers. Later, he was living aboard a sailing boat where he felt he needed to settle down in a land-based life as his first daughter was growing older. He then began living and writting his experiences while living a self-sufficient life with his family on rural smallholdings, in many books on the subject. Seymour was also an opponent to genetic modified food and industrialization, and an environment activist.


Bill Mollison (Australia, 1928-)

"Though the problems of the world are increasingly complex, the solutions remain embarrassingly simple."


Bill Mollison is a researcher, ecologist, naturalist and teacher, and the father of Permaculture. Permaculture is a system of permanent and sustainable agriculture, and also an integrated system of economics, self-sufficiency for local communities, human interaction and ecology. His legacy resulted on the creation of many permaculture farms and communities all around the world, adapted to many different climates.


Mike Reynolds


Reynolds is a architect based in New Mexico and a radical proponent of sustainable living and self-sufficiency. He developed a completely new self-reliant and ecologically friendly system of houses, called Earthships. These houses are made from natural materials, recycled materials, and can mantain a confortable indoords temperature even in very cold or very hot climates. The house collects and recycles water, allows food production and is equipped with solar and other alternative methods for independent production of energy.

More people will be added in the future. Suggestions are welcome!

Self-sufficient gardening - Growing vegetables in a shade garden

Today we harvested a few more vegetables from the garden.
We harvested potatoes (which were grown under only 2 hours of sunlight!), plenty of celery, plenty of cucumbers (in half-shade), and a few tomatoes (which are now slowing due to the lack of sunlight). The tomatoes in shade grow, but the fruits stay green and grow slowly. However, with just 3 hours sunlight, the plants gave a nice crop.

Our pumpkin plant is growing very long, it has several female flowers, let's hope that we can harvest in a couple of months a dozen of nice muskat de provence pumpkins!

I cut the zucchini. The plants were not cropping anymore, due to the lack of sunlight. I guess they are not adequate to shade gardens, and occupy much space. It's much better to grow the prolific cucumbers!! Each plant gave about 5-10 fruits.
We also have some beans growing and cropping (of exotic varieties).

Our jerusalem artichokes, chinese artichokes, yacon, skirret, taro, scorzonera, and tiger nuts, are still growing, and hopefully producing a nice crop of roots under. The yacon plant is huge, with giant leaves and nearly 2 meters high. I had to protect it from the wind.

We also have one plant of celeriac and a few new kohl-rabi. And our good king henry is growing fantastically well, with plenty of its spinach-like leaves for us to cook. The swiss-chard is another crop growing very well even under the shade of a tree.

The nice thing is, with so much mulching and shade, there is no need to water the garden for several days in a row.

The planning of our garden



CLICK IN THE FIGURE FOR SEEING IT IN HIGH RESOLUTION

Vegetables that grow well in our garden with little sunlight
Our garden stays between the city building in a half-shadow, humid place. There is plenty of trees and birds. At most, a few places receive about 4 hours of sunlight per day. Plenty of our vegetables seem to be growing well, such as the celery, lettuce, kohlrabi, rucula, broccoli, swiss chard, carrots, beets, and plenty of herbs. The potatoes are growing fast although slighty leggy. The tomatoes, squash and pumpkins are growing slower, since the place is quite cool. Inside house, in a southern window, they grow really fast! The peas are fruiting but are doing quite poor. Interestingly, the spinach is also very slow, but I guess it was due to the unseasonable warm weather.

A brilliant idea: surround garden edges with colorful flowers!
We have put plenty of flowers surrounding its edges, such as tagete, aquilegia, phlox and petunias. It was a wonderful idea to make an edge of fire-colours in one side with tagetes, and with white, blue, rose and purple colors, in the other side, with petunai, phlox, aquilegia and fuchsia!

Starting from seed: better start indoors and then transplant
The herbs grow really well. We have a few beans sprouting indoors (the mung bean is very slow outside). We also have plenty of celery and basil that started from seed (germinate slowly but it is so nice to see the tiny plants). One word of advice, the celery and kohlrabi seem better when seeded first in trays. The chinese artichokes and tiger nuts also failed to sprout. We have tiger nuts but we bought the plant. The jerusalem artichokes grow surprisingly fast and easily. They seem to require little water. The plastic protection, mulching and hair were excellent deterrents to the slugs and to prevent drying. Yesterday, we planted then sweet and black potatoes. What also failed to sprout were the quinoa and millet, we will try again. And the lentils and all legumes sprout best first indoord and then transplanted to a rich compost-soil afterwards. The problem is really since the weather is so dry (an entire month with no rain!), in places without mulching or compost, the tiny seedlings do poorly. Finnaly, sowing by the moon is a wise idea, if you want to avoid poorly growing seedlings.

Raised beds
Weeds is not a problem anymore. It was just in April they were vigorous. Now, a brief weeding is enough, considering the fact that our raised beds never gain any signficant amount of weeds! However, in the raised beds, the soil is richer but seems to dry faster, since it is elevated. This is a problem. There is some difference for a few cultures, but it is early to say, how better the crops fare in raised beds comparing to normal soil cultures. Mulching definitely helps, if we only add it after the crops are already 5cm high, to avoid the slug problem.

100 Square meters: enough for partial food self-sufficiency
Each side in the figure is about 10 per 10 m. We have plenty of lettuce, celery, rucula, potatoes and carrots. I guess the exciting part would be to see how much harvest will the root crops give (considering the alternatives we have selected: potatoes, yacon, tiger nuts, sweet potatoes, skirret, jerusalem artichokes...). We also have a dozen of tomato, cucumber and pumpkin plants, but definitely these are growing slower outside, but already have a few flower tips. It seems that this size (10 x 10 m, 100 square meters) is already enough for providing a substancial ammount of food for daily supply (except cereals, fruits and rice). With dozens of plants for each food, more than enough will be harvested in a few months, even in our garden with little sunlight hours.

In summary, we are very happy with the idea of growing our own food!

Growing your food in containers - how much for your self-sufficiency?

Suppose you have a 10m wide balcony
You grow your vegetables for your house-needs and ask:
How much is possible for your self-sufficiency?

1) First, our story (after our first year of harvests, a small-scale container experiment) growing food on your balcony
In 2007 we grew:
4 tomato plants (one per container), several containers of lettuce in spring and now in autumn, as well as radish, turnips, endive and rucula; 1 container with two peppers (few ones), 1 of potatoes (only for a week), 2 containers with peas, 2 with chickpeas, 2 with lentils (which were enough for 2 meals each, the usual for a week); only one container with strawberries which gave a very small but tasty crop, 4 brocculi, 2 eggplants which gave very small yields, some leeks and this was my humble first year experience. Some things had plenty of success and nice yields, other not so much but we were also not putting many expectations. This is more of a hobby and a soulful artistic activity for me.


2) Our plans for a realistic 1month self-sufficiency in a balcony (1 year growing) Edible container gardening
Clearly it depends on how much food you use, and on your diet
But we suppose a good uninterreupted harvest of veggies over a entire month, for a good supply (maybe lets say aprox more than half of your food comes from the garden)
I will try a small experience this year.
Grow in my 10x1m balcony vegetables for a month self-sufficiency (indeed the experiment is already running and greens coming to our meals!)
Unfortunely my lovely soul-mate and companion love is living abroad and will only follow this at distance ...
Helder I hope you fell also inspired by this!
And the same applies to many of you dear readers you come here for observing my funny nature-dedicated hobby!

I plan for the following:
6 containers of tomatoes, 2 with eggplants (half-month), 2 containers with peppers, 1 with a courgette and 1 bigger with potatoes, 2-3 containers with peas, 3 with lentils, 2 with broculli or cauliflower, 3 containers with turnips, 4 with lettuce and a few others with other salad greens, 2 with leeks, 2 with dozens of garlics, 2 full of radish, 3 of strawberries, 1 with kohi rabi and maybe adquire a few more berries (i am falling in love with their diversity)

... and maybe i am being overly optimistic!
But I remembered from the book conversations with god this important idea: Serve nature and Life, and you're serving the purpose of your life, and of yourself and all other beings

and this way we also aim at a more natural and soulfull way of living...


3) Lastly:


How many containers to grow for a one year self-sufficiency?
How many plants for true self-sufficiency? (Of course lets assume a continuous sowing and growing for a continuous supply over a year, which in some cases is not very easy, since some plants do not grow in cold weather such as tomatoes, and would need greenhouses. The key is clearly vegetable storage, which will spoken of on another day)


The total of containers for a year in underlined:
Tomatoes (sun facing walls, rich soil): 6 plants for summer epoch, meditteranean climates (and 18 others, for spring, autumn and winter, in greehouse or indoors), 24 in total, 1 plant per container
Eggplant (lots of heat and sun, rich soil): 4 plants for a epoch (16 in a year), 1 plant per container
Peppers (lots of heat and sun, rich soil): 24 containers of two plants, 2 per every month
Courgette (1-2 per big container): 12 big containers for a year?
Potatoes (2-3 plants per big container): 12 big containers for a year?
Fruit trees: not suitable for containers, try berries instead (3 containers with different berrie bushes should supply you with a good crop already)
Strawberries: at least 4 flat containers with some plants, for solely a spring-summer harvest
Garlics: 12 containers, each containing a dozen bulbs, should be enough
Leeks: 24 containers, each with a few plants, should be enough
Peas: 18 containers, sow 3 containers (4plants each) every two months
Lentils: lets assume, could be 6 containers (4plants each) for 2 months, that is a total of 18 for a year
Brocculi: these you can grow 2 plants per container for half month, grow 2 containers for month, 24 in total?
Cauliflower: never tried, but assume also 24 in total
Cabbages: does not grow well in containers, try 24 big containers for a year supply ?
Radish: sow 2 containers full of them every month, 24 in total
Lettuce: sow a dozen plants (4 containers), every month, 48 in total
Turnips: sow 3 containers every month, 36 in total (some for greens, some for bulbs)
Endive: 1 per month, 12 in total
Rucula: 1 per month, 12 in total, and as a note grow also some other very tasty less-known greens
Spinach: 2 per month, or 24 in total or maybe more
Beans, chick peas: not much experience with these; grow in big containers about 2 plants, and assume 5 containers are ok for a month, so some 50-60 containers should be ok!
Carrots: like parsnips (which even require more depth of soil), carrot is hard one for containers, try in deep containers (otherwise you will have only baby carrots, which nevertheless are very tasty), two containers is probably enough for a month, so assume 24 in total
Cereals: we have just harvest one container and gave the seeds to birds, lets assume 5 containers give not more than 2 week supply, 120 containers for a year? (lol)
Rice: ehehe, we tried but with no success!, but assume 50 drown containers and probably more for a year
Herbs (medicinal or aromatic): one container of proper size per each species is more than enough - these are the easiest to grow

Not counting with herbs or cereals, assume nearly 450 containers for your self-sufficiency! This should not disencounrage you, since this is equivalent to the space found on a small yard and is about only about 100 containers per epoch which perfectly fits on my 10m balcony.
Extrapolating, a small yard could in fact easily sustain true self-sufficiency for a person over a year, and possibly for a family, provide that soil was deeply cared and compost added every epoch. A row of 20-30 cereals should provide a supply for a year, but how am I to know about that since I have never attempted.

But as far as Permaculture is regarded, we should try the hardest we can to keep cooperation with nature, a equilibrium in the soil and with wild life and never commit the big mistake of our ancestors of over-explotation of soils and lands!

Love for all, Paulo
