Increasing Soil Building and Growing Capacity at The Energy Garden
Submitted by Aaron Friedman on Mon, 2008-02-25 15:58.
With spring fast approaching, two needs recently became
apparent. We needed to increase our sheltered growing space as well as our soil
building capacities. To accomplish this, we created several designs for
increasing our growing abilities, and in the end, we decided to build an
integrated system.
Currently, we have a worm bin and three bins for compost.
We built the new system in the middle of the garden and it will serve as the fourth
stage of composting. From this bin, we will sift the compost and create our
soil mixes. Because of its placement, it is ideal for distributing the soil and
seedlings throughout the garden.
Twenty-one straw bales were used for the walls, and we used
onsite scrap lumber for the frame of the cover. The cover is plastic, and we
plan on upgrading it with windows from the local recycle center. The growing
space is separated from the compost bin by a wall of straw bales.
To integrate the two spaces we cut sections of rain gutter,
which was onsite from our water catchment project, and put them through the
straw bale wall. This allows the solar gain from the cold frame to heat up the
compost pile during the day, and it encourages the compost pile to release some
of its heat into the cold frame during the night.
We have extended our growing season, soil building capacity,
and when the system starts to decompose the straw will make an excellent top
dressing throughout the garden. The cold frame and compost bin are also well insulated
by the straw bales.
The Signs of the Sebastopol Energy Garden
Submitted by Aaron Friedman on Mon, 2008-02-25 14:35.
Winter is almost over, and with it the time for
introspection also draws to a close. The heavy rains and shorter days have given
us time to create a sign system that illustrates our priorities in the garden. In
the coming year some focuses like crop selection and soil building will stay
the same, and this season they will be enhanced by a winter of planning that we
did not have last year.
Education is also a key priority as we enter the 2008
growing season, and one of the primary tools that we developed this winter is
our garden didactic system. This collection consists of 23 concept signs and 30
profile crop signs. They will be scattered throughout the garden to greatly
enhance its accessibility.
This project was beneficial to the Energy Garden initiative
because in the process compiling the content, we were able to summarize our
work to date. In addition, the signs helped us to identify the focal points of
the garden and the methods that influence its development.
The concept signs consist of:
·
Goals of the Sebastopol Energy Garden
·
Community Compost Collection
·
The Sebastopol Energy Garden Growth Collage
·
Square Foot Gardening Method
·
Natural Farming – The “Do Nothing” Method
· Cover Crops
·
The Water Catchment System
·
Drip Irrigation
·
Culinary Herb Spiral
·
Mandala Garden: The Sheet Mulch Technique
·
Methods of Season Extension: Towards a “Four
Season Harvest”
·
Appropriate Technologies
·
Processing and Harvesting Techniques
·
Tree Guilds: Edible Forest Gardening
·
Garden Cycle Tracking
·
Ethanol Production
·
The Fractional Still
·
Recycling and Compost: Designing “From Cradle to
Cradle”
·
Chickens
·
Biointensive Concepts
·
Permaculture Principles
Each sign corresponds to something that is happening in the
garden or that has influenced its progression. There are also 30 profile crops
that we have chosen because of their ability to help us adapt to Peak Oil.
Instead of a lawn, we are selecting a great range of crops to benefit humans
and the environment. Please see http://www.energyfarms.net/node/1495 for a list
of these crops.
These signs will enable people with a wide range of
understanding of sustainability to experience a transformed suburban lawn. When
people visit this year, during our second growing season, they will be
introduced to a diversity of crops with a large variety of functions. In
addition, they will be exposed to techniques and technologies that are easy to
learn and have the potential to make a big difference in their lives.
The rains will soon stop, and spring will bring a time of
action. We will sow seeds of diversity in the garden and hopefully, inspiration
in the community. The Energy Garden is always open to visitors and we look
forward to helping more people experience the resilience of the Earth.
A Picture Journal of Fall Cleanup, Harvest, and Planting

Regenerative Design Institute Visits The Energy Garden
Submitted by Aaron Friedman on Tue, 2007-10-16 13:20.
In a brief six month turn of the calendar the garden
at the Post Carbon Institute in Sebastopol has become a living demonstration of
possibility. With fall upon us, and a vernal growing season under our belts,
the best harvest of all has been the feedback from the community. Coming in the
form of encouragement, insightfully probing questions, group brainstorms, and
design charrettes, this garden has lit a spark.
Beyond the beautiful and energetic presence of the
plants and their relationship with the soil, the garden is beginning to come to
life. With each new visitor, from neighbors detoured on their walks to
permaculture courses of 20 students, visions are entertained of an abundant
relocalized future.
Sunday October 14th, was an
especially engaging day. The Regenerative Design Institute’s Four Season
Permaculture Course visited the Energy Garden and left a beautiful mark. They came with
twenty students and naturally, due to the style of the education at RDI, formed
a circle in the gazebo. President Julian Darley welcomed them to the garden and
provided the context for the work here saying, “We want to leave something for
the next generation. We know that there will be big changes in the Twenty First
Century and our goal is to ensure a future for the twenty second century.”
After going on a tour of the Garden the students
broke into four design charrettes. A charrette is a small group brainstorm that
focuses on specific design objectives. On Sunday we focused on:
- Stage One Water
Catchment and Constructed Wetlands - The Processing /
Harvesting / Potting Bench / Workshop Area - Site Access Pathways
and Water Reclamation - The Social Structure of
an Energy Network
After the tour the students chose a charrette and
over the next hour proceeded to engage in a condensed design process. Each group was given design objectives and
asked to create a recommendation to address the needs.
The “Stage
One Water Catchment and Constructed Wetlands” charrette was given the
following objective:
With
the given plot, design a system for catching water from the asphalt roof of the
1,500sqft house. Consider how the water will be caught, filtered, stored,
cleaned, and distributed into the garden. There is the constraint of a having
to maneuver a previously existing concrete wall. Please include the biological aspects of permaculture,
(appropriate plants, soil, bioremediation, etc.) as well as the mechanical aspects (pumping,
filtration, storage, collection, distribution, etc.) in your design. Please
consider all inputs (i.e. water,
energy for pumping, money) as well as how the outputs (i.e. biomass, clean water) of this system may be
maximized. Try to integrate a means of measuring water input and output into
your design.
Their
design focused on the principle of “Slow it, spread it, and sink it”.
SLOW
IT: From roof via a water chain into a three barrel system. The first barrel is
for catchment, the second for habitat and plants, and the third for storage and
plants. The output is a y-valve to either a faucet for a watering can, or to
swales.
SPREAD
IT and SINK IT: From barrels into swales going to the garden. Or with watering
can.

The
“Processing / Harvesting / Potting Bench
/ Workshop Area” charrette was extremely creative. I facilitated this
group and given the following objective they created a beautifully dynamic
design.
The
Energy Garden at Post Carbon Institute needs an outdoor processing area and
workshop space. There is a current and pressing need to have a zone to prepare,
handle, and process the seasonal harvests yielded from this garden. Please
consider a constant flow of inputs and outputs. Try to design a system that
handles large harvests (corn, sorghum, community compost) and create stocks of
seed balls/ seedlings on a regular and monthly basis. Key needs to be incorporated are:
Large
surface space for seedling bench, Accessibility,
Efficient use of space (stack the func),Outdoor water source for spray table and sink, Outdoor kitchen
capacities, Greywater/ reclamation/ catchment, Shelter, Weighing area (with
good access), Weatherproof logging area,Storage area (seed starting materials,
harvest baskets, hand and small harvest tools)
Reese
Baker, graduate of New College’s eco-agriculture program facilitated the
charrette focusing on the Site Access
Pathways and Water Reclamation. Given the time, they were able to
analyze a little more than half of the property. Their challenge was:
As
a group, your goal is serve as a consultant with the objective of creating a
design for an in ground water catchment system for this site. Be sure to take
into account basic design considerations when creating the site plan. These
include the directional flow of water such as runoff from hardscapes and access
points such as pathways.
Utilizing
the eight principles of rain water harvesting taken from Rain Water
Harvesting for Drylands:
- Thoughtful
Observation: Low + High Spots. - Start
at the top - or highpoint - and work your way down. - Start
small and simple: labor, materials, etc. - Spread
and infiltrate the flow of water: swales, keyline, ponds, etc. - Always
plan for an overflow route and manage that overflow water as a resource:
spillways, runoff. - Maximize
living and organic groundcover: native vegetation. - Maximize
beneficial relationships and efficiency by “staking functions”: plant used to
harvest water could include food, fiber, fuel, wildlife habitat, medicine etc. - Plan
for reassessment of the system: will the materials be appropriate over the long
term?
Their
findings were:
- Incorporate
in ground biofilter at the highest point (near road) - Replace
concrete driveway with permeable pavers - Divert
runoff water from curb and water through a biofilter and into a small pond or
ethanol producing plants near front fence. - Use
on contour drainage to avoid driveway runoff into garage. - Create
a dry creek bed from front steps connecting to the back garden. - At
the bottom, shaded part of the property, create mulch pile under trees for
mushroom cultivation. - Slow
it, spread it, and sink it.

Mark
Sardella, our new director of operations here at Post Carbon facilitated the
charrette that focused on the design of an Energy Network. Mark’s background is
in engineering and renewable energy systems and for the past six years he has
focused on local energy solutions. He was also core faculty at Ecoversity in
Santa Fe, New Mexico.
His group looked at the social
design of a local energy network, and therefore faced the hardest challenge of
our four charrettes. Essentially, in one hour’s time, they discussed the
transition from the current design of the industrial system to a more
integrated and local system that honors all life.
Impressively, they were able to come
to a general consensus on an approach to take. They decided that focusing on
the promotion of the non-dual nature of reality, giving children and the youth
a voice, developing local energy descent plans, revoking corporations from their
status of personhood, and creating and networking collaborative co-operatives of
groups doing similar things (i.e. guilds of people doing childcare, ecological
restoration, etc.) Given five minutes to
present these were their findings, and their charrette rose to the challenge.
The Energy Garden at
Post Carbon Institute was greatly enhanced by the two and a half hour visit
from the folks at RDI. Like rich compost, the input of these budding
permaculturists will be integrated into our operation here in the future. As we
move into winter we will be focusing our attention on the systems for
processing the harvests, retaining the water, and designing systems for
networking the Energy Farm concept. With mutually beneficial alliances and the combining
of resources and ideas, visits like these have shown us that the best harvest
of the season has been the input from our community. With gratitude, we keep
planting.

The September Garden Tours: Transitioning to Action With a Harvest of Hope
Submitted by Aaron Friedman on Fri, 2007-10-12 10:55.
As the Jerusalem artichokes danced fifteen feet in the air
and the millet waved majestically, the corn and sorghum rustled rhythmically with
the breeze coming from the west, the harvest was celebrated. Once a battered
and neglected yard, infested with Bermuda grass and trash, after one season
of love, intention, and care the demonstration Energy Garden at the Post Carbon
Institute was born. Now teeming with crops that even some seasoned gardeners
have never seen; the kenaf, switchgrass, quinoa, sorghum, and other plants
represent a resiliency and bounty that inspire hope and action. On three days in late September the community
learned about and participated in home scale responses to current global
problems.
On Tuesday, September 25th the Permaculture Class
from the Occidental Arts and Ecology Center (OAEC.org) arrived with thirty people to see the Energy Garden. Well informed
and motivated by the holistic education delivered by Brock Dolman and other
teachers at OAEC, the students engaged in an interactive tour and design
session at Post Carbon’s Energy Garden. To see the details of the design
charrettes please see the blog at http://energyfarms.net/node/1397.
The two hour tour was stimulating as the students learned about the context of
Peak Oil and the purpose and reasons behind the Energy Farm Network. We here at
Post Carbon also benefitted from their understanding of permaculture theory and
design as they suggested several great ideas to improve the Energy Garden site.
Three days later, on Friday, September 28th, the
next day of tours began and about twenty people participated in a series of
free workshops. They learned about ethanol production, appropriate
technologies, and relocalization. The attendees were engaging and several deep
discussions were sparked about responses to the coming transition. As the
methods for developing the Energy Farm were shared, hopes and fears about a
world with less oil were addressed with thoughtful questions and creative group
brainstorms.
Our last day of tours was on Sunday, September 30th.
The workshops were the same as on Friday, and they were honed
to a more family oriented atmosphere. Forty-five people came over the course of the day
and a third of them were children who showed enthusiasm that provoked smiles
all around. The day was filled with joy and laughter, making relocalization a
reality rather than a mere idea. People harvested vegetables from the garden,
used a leg powered Japanese winnower and a mill to process wheat and barley. The bio fuel discussions led to good connections and the sharing of knowledge.
The tours marked the end of summer for us at the Energy
Garden. We are excited to transition into the rainy season and we are currently
planting crops to feed the soil. As we work in the garden, it is a joy to see
cars slow down to look into our “yard”. With time the interest will continue to
rise and hopefully these types of gardens will proliferate. Until we see you again,
enjoy the autumn.
Learning to Network Like Bermuda Grass
Submitted by Aaron Friedman on Fri, 2007-10-12 09:56.
Wednesday was the new moon, so according to biodynamic principles
we have a three day window on either side to start new seeds and plant
seedlings that we started on the last new moon. To prepare for this time, I put
forth a semi-frantic burst of action, harvesting the millet, amaranth, quinoa,
corn, and flax. I have weeded and cleaned nine beds, roughly 1000 square feet,
and now that the frenzy has slowed I am completely haunted by the Bermuda grass.
Yes, the amaranth was a stunning orange, and the yield from
one bed was impressive and exciting. Sure, it was the first time I have seen
quinoa growing in a garden, and it was delicious. The corn, millet, and flax
can make fuel and feed nations, but on more than one occasion in the past week,
I have had dreams (read: nightmares) about Bermuda grass.
After three days of weeding in the hot sun, with the sounds
of birds and cars to keep me company, the rhizomatous pattern of this invasive
weed probed its way into my subconscious.
The grass creates a long chain, penetrating at least 8 inches deep
(probably more) and it relentlessly spreads its way across any open ground. Its
pattern is uniform, its behavior is consistent.
Preparing the beds for the winter crops, as is usually the
case with gardening, I was left with my own thoughts. Daily, my hopes and fears
surfaced as I thought about the state of the world in forty years. I continued
to pull the Bermuda grass. The work developed a rhythm and the birds provided
the melody.
For entertainment, or perhaps because it is harder to
completely quiet the mind, I allowed my thoughts to create pictures of the
future. On the fear end of the thought spectrum, I saw the suburban landscape
as wasteland, ghetto, and desert. Cut off from cities, which were controlled by
a repressive and authoritative government, there was hardly any productive
human activity and the flow of goods and services was extremely limited. Visions such as these are demoralizing and
self defeating, and one night last week, the night of the Bermuda grass
nightmare, I allowed this perspective to darken my mood and disrupt the rest of
my day.
Late last week the energy at Post Carbon Institute was
infectious. There was a slew of activity as more than a dozen people came
through for meetings, tours, and to see the new electric Ford Rangers. As I was
working, I again let my mind entertain itself. This time, with so much
collective energy focused on creating positive responses to global problems, visions
of hope and renewal uplifted my day. The same communities that the day before
were devastated by peak oil and climate change, were thriving. The pace of
travel and the movement of goods were also slower, but the more densely planned
neighborhoods were teeming with life. Gardens were in full bloom and there was
laughter everywhere. People were riding bicycles and there were
baskets offering surplus fruit in front of every house.
Needless to say, with visions of possibility and renewal,
the Bermuda grass came out easier than when I imagined destruction. After a long and insightful week of garden
maintenance, I notice a choice. I can label the Bermuda grass as an unwelcomed,
invasive, and obnoxious problem. Certainly, that would have some truth. Or, I
can see the plant for what it is. By covering the ground, breaking up the soil,
and setting roots relentlessly, the plant is useful for certain functions.
Regardless of how I judge it, I want to model my activism
and work after this fierce plant. Seeing the pattern of its growth, it is
consistent, resourceful, and strong. It
works in network with other strands of its family to create a comprehensive web
that works underground and above the surface to create a movement that will
never be nullified. In order to see my visions of hope and positive change come
true, I will take this lesson in work ethic from a plant that I might otherwise
label “invasive”.
The Garden Gets Curvy
Submitted by Aaron Friedman on Wed, 2007-09-26 17:12.
We have again added bed space to the Energy Garden, this
time in the shape of a mandala. Utilizing techniques from Gaia’s Garden
by Toby Hemenway, we are slowly building the hardpan barren “lawn”, read: super
invasive bermuda grass and clumps of dead sod, into nutrient rich humus. As double
digging was near impossible, we are letting the worms to the work by creating a
sheet mulch close to 18 inches thick.
First we created the design for the area and then marked the
edges of the mandala on the earth. Next we began creating the bed. Otherwise
known as lasagna gardening, we chopped away some of the clumps of grass and started
with an inch layer of manure. We followed that with cardboard, then with an
inch or two of organic vineyard compost from Grab and Grow in Sebastopol. According
to the grab and grow website, it is “made
from a simple blend of grape pumice, green waste and oyster shell flour, this compost
has no manures or supplemental nitrogen fertilizers added to this high
potassium mix.
This was
followed by a single “book” layer of wheat straw, then with another inch or two
of mango mulch. “It doesn’t have any mangos in it, but it does have horse and
cow manure to supply basic nutrients; grape and apple pumice which are high in
beneficial bacteria and yeasts to aid with the breakdown of organic matter;
rice hulls and straw for good soil tilth; soft rock phosphate and greensand to
boost the phosphorous and potassium.” This was followed by a layer of alfalfa
straw and wheat straw mixed together. We will plant by opening pockets in about
a month.
Next we created
the paths by laying burlap bags donated by Taylor Made Farms in Sebastopol. On
top of the burlap we put down woodchips. The irrigation was then laid under the
straw. We have also sheet mulched and
prepared a new berry patch next to the sunflowers and driveway in the front of
the house. In an epic battle with the Bermuda grass we have also sheet mulched
all of the paths on the property with cardboard and woodchips. We hacked down
most of it and hope it never comes back. It looks great right now.

Before...
After... let the worms do the digging!
OAEC Permaculture Course Tours the Sebastopol Energy Garden
Submitted by Aaron Friedman on Wed, 2007-09-26 16:44.
Arriving thirty strong, equipped with cameras, notebooks and perspectives
freshly shuffled by a week of holistic earth care instruction, OAEC's
permaculture class toured the Energy Farm. They came a little after ten and over
the next two hours engaged in a participatory dance throughout the small
suburban site. President Julian Darley addressed the students as they
surrounded the front "yard", now in full bloom with broccoli, millet,
basil, peppers, and many other beneficial plants.
He spoke about the philosophy guiding the Energy Farm Network and the urgent
need to relocalize our food and fuel production. Darley challenged the students
with problems about bio fuels produced using industrial agriculture citing the
huge amount of land and oil that it takes to grow and process these crops. In
his brief fifteen minute intro he gave the students some context related to
peak oil and the adaptation process we face in this lifetime, calling this time
the "great transition."
Brought by Brock Dolman, permaculture elder and master instructor, this tour
was special because it was a large group, very well informed and keen to learn
about and address the deeper challenges of such an ambitious project. After
Julian finished, we divided the group. Half went on tour of the grounds and the
other half engaged in mini design charrettes. After forty minutes the groups switched.
We created four design charrettes aimed helping the students practice their
site analysis and design skills. Each charrette focused on a zone of the
property. The four charrettes were called the Fukuoka forage forest, zone one
patio, sixteen square foot garden bed, and water.
The “Fukuoka Forage Forest”, named after Japanese farmer Masanobu Fukuoka, focused
on the back part of the lot under the apple trees and adjacent to the fence.
The students came up with several good ideas to implement in the zone furthest
from the house: cob benches for seating in the gazebo, an outdoor kitchen to
process food, a cob oven, an outdoor shower, more worm bins, incorporating
bees, temporary fencing for chicken forage, mushroom cultivation, introduction of
ducks to the system, a possible pond under the largest apple tree, birdhouses,
creation of roof structure over the chicken coop for roof catchment and shelter
for birds.
The zone one patio refers to the area closest to the house in the back.
Currently, hot and inhospitable with crushed rock and concrete, the area is
relatively neglected considering the proximity to the house. The students focusing
on this area envisioned; an arbor on the porch, a trellis of kiwi and grapes,
planting a fast growing shade tree, breaking up all the concrete except under
the patio and doors, using broken concrete for pavers to make paths, using the
fence to grow vines on, cultivate bamboo, sandbox in corner with cob walls with
planter pockets, planning a soft ground cover, hanging pots from the eves,
building a culinary herb bed.
The charrettes that focused on water produced an assessment of the incoming
water and cited some of the future tasks for addressing the issue further. They
mentioned: municipal water input, runoff from street and driveway, conservation
techniques, the need to get an accurate square footage of the every roof on
property to calculate water catchment capacity, a need to find the highest
elevation on roof for downspout, a need to find a place for storage tanks, how
to handle wastewater, and they looked at ways to “slow it, spread it, and sink
it.”
We currently have six pocket gardens that are four feet by four feet. We
challenged the students to create planting plans that focused on a theme. One
group chose to create a plan with a medicinal focus, and the other focused on
companion planting with a 60 % calorie, 30 % carbon, and 10% vitamin ratio. The
group that keyed in on medicinal plants decided to sow in a spiral pattern with
echinacea in the center followed by chamomile, lavender, jewelweed, nettles,
mullein, ginseng, purslane, plantain, yarrow, selfheal, valerian, comfrey,
ginger, garlic, and dandelion. The 60/30/10 group decided to plant in a symmetrically
opposing pattern of strawberries, spinach and lettuce, calendula, pumpkin,
amaranth, and scarlet runner beans on trellises.
The hour and forty five minutes was extremely productive as it exposed the
students to the desire to create an energy farm network and it also provided
some key input as to future improvements of the land here in Sebastopol.
Everyone seemed to leave energized and motivated and it was great preparation
for the community tours on Friday the 28th and Sunday the 30th.
In closing, Julian reminded the group that in order to adjust to the coming
changes we need to “reduce consumption and produce locally” and that these two
things are inevitably intertwined because as we begin to produce locally we
will reduce our consumption and as we reduce our consumption because of peak
oil we will have to produce locally. May our net work guide the way.
