Gardening is an ancient craft that grew in importance as a matter of "food security" over the course of the Great Recession. Even so, gardening will not become a widespread skill as long as our system of agriculture monopolizes how we are fed, and what we learn to eat. Agriculture as we know it seems committed to a path of innovation that views soil health and seedstock as solely a commodity, and something we can replace with the chemical and biological innovations of factory farming.
The green revolution of the 20th century, with all the good it has done, will not sustain our health through sterile mediums in hydroponic greenhouses alone. Our human genius for working with plants must itself be cultivated by a new generation of children who enjoy growing seeds and nurturing them into fruit bearing plants. The Nurse Tree Arch is an innovation that I hope can contribute to immunizing the generations to come against what author Rchard Louv describes as "nature deficit disorder," the atrophied awareness and development of our senses that comes from lack of experience with nature, in both it's sublime and dangerous aspects. I believe gardening is one of many ways we can cultivate such an experience and awareness. At the same time, the arch is a tool for bridging gardening culture into a time of much hotter growing conditions.
1) I'm excited to report that Sky Island High School Principal Shari Popen and parents associated with Drachman K-6 Montessori school express interest in fundraising to build arches as a complement to their gardening and ecology programs.
2) The Prototype Raised Bed Arch funded by Scott and Edna has loaded the 2 yards of 60%/40% soil compost mix from Tanks Composting over the 3 yards of gravel that with a fan and perforated landscape pipe comprises the heating and cooling system. Scott calls the arch "my cathedral." Scott and Edna have seed catalogs and plant guides. By the end of January they will be germinating seeds for their beds. What remains is to hook the arch to electric power for the fan, install the Aluminet shade screen, and finish the rims of the bed with some Mexican tile.
3) When I returned home I opened the December 23 & 30th New Yorker to an article titled "The Civilization Kit" that features Marcin Jakubowski's project, the Global Village Construction Kit. That in turn led me to find out more about Shop Bots: computer controlled routers and milling machines that can produce (out of plywood) something as large as a New Orleans Row House, or as the builder's describe it, a Wiki-house. The Shop Bot may be helpful in developing the arch along the path from craft item (200 plus hours of labor time) to a product that could be manufactured to order much more quickly, shipped and assembled more easily. See a photo of the Shop Bot and Wiki house below.

Earlier this week Michael installed a hugelkultur bed for a client in preparation for assembling a Patio Arch in the fall (see photo above). This is for Barbara Warren, the second pioneering arch client! This will also be the first combination of the "sponge mound" technique with the all-season arch.
Yesterday Arizona Daily Star contract writer Elena Acoba interviewed Michael for a June 29th Sunday Garden Section article about the Nurse Tree Arch project! This is a huge opportunity and further sign that piloting the manufacturing process for the arch is a timely development.
Another milestone moment occured today when Michael had his first face-to-face meeting with Gary French, the owner of CNC Routing AZ - the business that will manufacture the components for the 4th Prototype arch and a new version of the Patio Arch.
Gary has 28 years of experience with milling, originally as a cabinet maker. When the recession crashed the building industry, Gary pivoted to serve a diverse set of businesses for whom he mills parts out of aluminum, plywood and a host of other materials. His wealth of knowledge about materials is already aiding the Nurse Tree Arch project.
See photo below of Gary and Michael standing with the Onsrud Panel Pro milling machine. Gary describes it as "scary powerful." That is why there is a yellow "keep back" line around the machine!

With a combined $700 cost for cutting and materials, $1525 could get us the CNC router-cut frame for the fourth prototype and a second frame for the new display arch. With another $475 in contributions we would cover the cost of the Solexx glazing and Aluminet screen material for the next prototype arch.
Proposal: Let's finish the last six days of this campaign with a push to get to $2000 or more in contributions. When this campaign fails to reach the $6000, we will start a second campaign at $2000 or more.This will harvest the good will and contributions you have made in this first round.
That will make it possible to move the Nurse Tree Arch Project forward toward it's goal of a marketable product by January 2015.
Michael will still need to find other ways to fund infrastructure needed to move this to a business footing: an assembly facility that is air-cooled, Insurance, advertizing, legal advice.
All you need to do is contribute before the May 30th deadline, so we can calibrate a goal for the next campaign. See link to site below:

Did I mention planting three fruit trees, building hugelkultur beds, planting more seeds, tending the garden and working on a consulting contract with Partnering Resources in Boston. Yes, I am busy. That is why I call it Protirement. Here are some photos showing developments.

How many arches have I built? The first was constructed as a shade structure in March of 2012. This basic 2 x 4 and gusset structure underwent a Kickstarter-funded transformation of into an all season "green to screenhouse" completed in January 2013. The second arch is a smaller display version dubbed "the Patio Arch" which made its debut at the Earth Day celebration in April, 2013. Scott Rosenbaum funded construction of the third- a raised bed arch. The current manufactured (rather than craft built) patio arch is the fourth, and it will be followed soon after by a full-sized manufactured arch which will be #5. This fourth arch is producing data on manufacturing costs (close to $1500) and finishing costs (probably another $1000-$2500 depending on the design). A sixth and seventh arch are to follow for two "early adopters." Drachman Montessori school is in the process of procuring grants to build arch #8 for its ecology program.
The photos below illustrate the current finishing process on Arch #4. This week it will all come together in time for assembly at the Envision Tucson Sustainable Festival. See the announcement above for time and place.

IT IS A FACT THAT WITH A COMBINED $5000 FROM CROWDSOURCED CAMPAIGNS THIS YEAR AND LAST, MUCH HAS BEEN ACCOMPLISHED. BY THE END OF AUGUST OUR NEW MANUFACTURING PROCESS WILL GENERATE BOTH A 4TH BERMED-SIDEWALL PROTOTYPE AND A 5TH PATIO DISPLAY ARCH, ENABLING US TO BEGIN OFFERING CAMPAIGN SUPPORTERS MANUFACTURED ARCHES LATER THIS YEAR. BY JANUARY OF 2015 WE EXPECT TO HAVE FIVE ARCHES OPERATED BY OUR EARLY ADOPTING CUSTOMERS IN PLACE - READY FOR THE SPRING TO SPROUT.

I'm designing the Nurse Tree Arch for this future of continued drought and heat, for I believe it is coming whether we like it or not. In fact, it is the future we already experience today. Controlling the temperature of a garden bed means also controlling the water those beds retain. My work with hugelkulture beds is in this same vein - finding ways to help the soil stay moist when it is bone dry and the wind is blowing under a hot sun. Gary Nabhan speaks of this challenge in his book Growing Food in a Hotter, Drier Land:
"In essence, to become better food producers in the face of climate change, we must learn how to become better "water and food system plumbers," redesigning our water delivery strategies to best meet the needs of our food plants."
Arch Updates
1. January 13, 14 and 15 I participated in another of Gary Nabhans groundbreaking projects, the Arizona Food and Farm Finance Forum.
2. I'm moving the project to a business footing:

As we complete what will be the warmest year on record in Arizona, plants inside the arch and outside in the food forest show what can be done to produce food year round. Blessed be all the wonderful support people who make this citizen science and small business development possible!

In order to produce arch components with a computer numerically controlled (CNC) router, clean and concisely described components must be drawn and rendered in a file the computer can read. I am using Google SketchUp Pro to produce both two dimensional drawings and a three dimensional model to test the fit of components. The drawing below demonstrates the progress made in this regard. This is the rendering of the components for the 4th prototype, and I hope to have components milled by the end of August. I'm reducing my competing commitments to make this happen, but eldercare and back problems stand in the wings to challenge my focus. I've helped my mom make progress, and with some physical therapy I will get a sore bursa and wobbly back in line as well.
The peat pots enjoy the humidity in the arch, and watermelons were up and secondary leaves appearing within a week. The lettuce need more time in their grow pots before transplanting outside.

On Sunday June 29th, the Arizona Daily Star will run a feature story in the Garden Section on the Nurse Tree Arch Project. People will contact Michael and want to know about cost, where to see the arch, and when will it be delivered?

This winter solstice represents not only the return of the sun's light, but the beginning of the end of the prototype process. The Bermed Arch will demonstrate the capacity of earthen sidewalls to help keep bed temperatures in control on raised beds, without subterranean heating and cooling using warm moist air piped into a gravel heat sink.
This view (see below) does not show the south facing solexx wall and double doors so that the ferrocement raised beds are visible.
Note the adjacent 1320 gallon rainwater harvesting tank. The Nurse Tree Arch is designed to make gardening with rainwater a practical reality.
ARCH UPDATES
1. Preparation of the articles of incorporation for the L3C business entity are complete and ready for review by consultant Sy Rotter. Arizona does not have the legislation for the low-profit limited liability company. I will incorporate in Vermont and then apply in Arizona as a foreign company. I'm taking the time to do it this way because the values of the Nurse Tree Project align with many non-profits in regards to helping people to learn how to feed themselves. We expect many of our partners to be non-profits and want to make it clear that our values align, thus the emphasis on low-profit when we seek investment funding.
2. While the business entity is forming, we have purchased Quickbooks and begun a relationship with Sabino Canyon Accounting LLC and Valarie Levine, CPA, EA. Thanks to Valarie, the Quickbooks are loaded and ready to use. Scott Rosenbaum is also helping with a spreadsheet that can help calculate business metrics.
3. Research into fabricators with computer numerically controlled routers is leading toward several businesses up the road in Chandler, AZ. Next step is to prepare a sample arch frame design in Google Sketchup, and seek help in producing a prototype arch with the new computer-assisted fabrication process. As soon as I select a fabricator for the prototype build, I will set up a crowdfunding site (possibly Indiegogo this time around), and seek support for construction of a fourth prototype using berm sidewalls and the new framing process. I hope this can be accomplished in March. Stay tuned!
4. Meanwhile, Spring is nearly sprung in the Southwest Deserts. The land is parched, and there is always the danger of a late frost. This calls for more water system plumbing projects. I've got five new hugelculture beds to add to the two I used last summer to raise squash under the canopy of the Palo Verdes, Acacia and Mesquite. A Black Jack Fig is planted, and will be joined by a Spanish-era Pomegranite and a Mexican Lime in early March. With the existing Lemon, Olive, Chiltepin pepper and Mesquite, our backyard food forest is taking form! My existing keyhole bed got refurbished with the installation of a perforated landscapers pipe underneath a hugelculture-style bed leading to the future location of the Pomegranite tree - a white 5-gallon pail. See pictures below.

The Monsoon rains arrived July 3rd with a contribution of 1/2 inch of rain on our workshop watershed - about 300 gallons in the Cistern. July 5th another 1.27 inch of rain fell. The 1320 gallon Bushman cistern is now holding about 1000 gallons with room for another 1/2 inch of rain. The arch is now watered primarily by the water in the cistern. Rain is directed to the beds by the Solexx panels inserted in structure's side like wings: what I call the raincatcher mode. It was this configuration that weathered 60 mile per hour winds during the July 5th storm. The drought weakened eucalyptus lost more limbs in this storm.

In his own defense Michael claimed that seasonal variations in temperature were out of his direct control. He lamented that the Snow Pea's are upset at not seeing any snow, as was the case last year.
Readers of this blog know why I think the Nurse Tree Arch is important. If gardening is to survive as a vocation on the new planet we are crafting, it will need to control evaporation and transpiration. Keep the writhing mass of organisms we describe as soil at a temperature below 85 degrees in the summer and above 60 degrees in the winter. Happy soil organisms equals productive plants. The structural solutions offered by the Nurse Tree Arch help make this happen.
I chose to organize as a low-profit, limited liability business. This type of business entity attracts investors who share the values of the enterprise.
“The low-profit, limited liability company, or L3C, is a hybrid of a nonprofit and for-profit organization. More specifically, it is a new type of limited liability company (LLC) designed to attract private investments and philanthropic capital in ventures designed to provide a social benefit.” -Non Profit Law Blog
By reducing the focus on profit taking, the L3C form of organization is explicit with investors that the path forward involves maximizing investment in the service of its social progress goals, rather than making investor wealth building the center of the universe. At the same time, investors can help assure that the investments are smart and productive. Arizona lacks the legislation needed to get that form of organization. That is why the Nurse Tree Arch Design is organized through the State of Vermont.
As an innovator amidst a groundswell of interest in sustainable food supplies, Nurse Tree Arch Design is destined to face many moments of truth. My job as the inventor and business owner is to move through the business making process with integrity as I organize a way from early adoption to mass acceptance of sustainable gardening methods, structures and tools. I hope the L3C will attract investment from foundations and individual supporters.
Are you interested in supporting this Nurse Tree Arch enterprise? In the month ahead you will have at least three ways to help this business grow.

The sandy soil is excavated a foot deep. Relatively small amounts of Portland cement (an energy intensive material) are mixed with water to make a 12 inch deep foundation and a 24 inch high solid wall, thick enough to be stable and functional as a storage mass for the heat of the day. This will create a vessel into which we put a hugelkultur heart - carbon for the microbes and fungi to feed upon, deep below the top soil mixed with compost and the remaining soil. The Nurse Tree Arch spans overhead, providing further protective summer shade and winter cover.
Is it a scalable model, ready for large scale farming? Absolutely not. Yet it is a conceptual departure from normal practice, and a spur to think through what it will take to continue kitchen table gardening on a hotter planet and in a desert environment. From this prototype and others will come understandings about how to care for the underground life that is missing in our current cultural fixation on above ground leafs, stems and flowers. From this shift in perspective may come the capacity to keep trees alive, to keep soil alive and growing our favorite vegetables, and thus to supplement our food and keep the atmosphere from becoming a completely toxic mix of carbon dioxide and methane. I suppose this is the closest I can get to the Nurse Tree Manifesto: Keep microbes happy, and continue to grow what you eat.

Welcome to the newly redesigned Nurse Tree Arch Project Blog site!
This site documents the business development process for the Nurse Tree Arch. In it you will find a record of every milestone achieved since the original shade structure was built over four days in March, 2012.
The Project is currently testing the newly assembled Entry Arch installed as a annex to the original first Nurse Tree Arch prototype. A full size version of the mortise and tenon design (Dale's arch) was recently completed. It features a hugelkultur deep bed with cement board side walls buried three feet deep.
You can also find out more about this innovative garden product at our Nurse Tree Design page, and our

You can help Michael prepare for this golden opportunity.
1) If you haven't already - contribute financially to the project. The $2250 goal of this second Indiegogo campaign only covers the cost of cutting and purchasing components for two arches. There is no margin for covering other costs. There is no better time to contribute.
Go to: igg.me/at/NTarchesforeveryone
2) Let Michael know if you would like to become part of a team to make this opportunity one that will build confidence in the capacity of Nurse Tree Arch to deliver. Initially this will be a voluntary effort. Help will be needed to set up bookkeeping, help with marketing and sales, assemble and test the new materials. This Summer will be spent sorting out the true costs of the business model. If this interests you let Michael know.
