Una Carta De Amor

Calendula My Sweet,

Your purposes are endless; Let us begin with edibility.
You are fit to be eaten in colorful confetti salad and herbaceous potato soup.
Your dried petals can be muddled in jojobaoil or grapeseed oil for a taste of infused cookery.
For the chickens, your extract can be added to seed for enhanced brilliance of yolk.
You nest in my medicine cabinet…
You boast anti-viral, anti-genotoxic and antiseptic properties.

Enough of the anti; On to the pro!

Your tincture is soothing for Peace of Mind, Body, and Spirit. To reduce inflammation, to ease abdominal cramps, and to treat irritated epidermis. You heal wounds and sore throats; Is there anywhere you dare not venture?

You are beautiful in my garden, so easy to grow. Beautiful on my patio in a pot, the root of your common name “Pot Marigold.”

Calendula, I am grateful for you.

The Permaculture Design Certification course is sometimes described as a ride on a whitewater river raft.

There will be exciting rapids that get our hearts and minds racing with enthusiasm, action and hope. Other times there will be peaceful, though-provoking pauses with amazing vistas, reflection, and response.

And along the way, there will be a number of different topics such as soil, water, energy, and trees. The topics, each branches and forks in the river, winding down deep canyons. Each canyon could take a lifetime to explore.

Starting this Sunday, September 19th, we are very excited to begin to explore deeper into one of these canyons with the Deeper Dive: SOILS classes at Hayes Valley Farm.  Classes will be offered twice a week, on Sunday and again on Monday from 3:00pm-6:30pm.  Each week, the three hour class will introduce some of the basic concepts of soil health, compost, worms, compost teas, and soil science. 

In October and November, we'll go even deeper, with Deeper Dive: WORMS, Deeper Dive: COMPOST, Deeper Dive: COMPOST TEAS, and Deeper Dive: SOIL SCIENCE

Beets need boron. What’s a boron? No silly, it’s not a name you call someone you don’t like… It’s a mineral that helps beets develop deep taproots and skin tough enough to keep out the bugs. Boron is the most widely deficient minor nutrient in vegetable crop soils. It is required for protein synthesis, and increases crop yield, flower set, and vegetable quality.

So …. back to beats. Besides being famous for thriller sized crowds at Michael Jackson concerts, beets can serve as a culinary centerpiece in your home. We’re not talking about the nasty canned beets many of us have been forced to eat by Grandma as part of a childhood dinner. We’re talking about the magical root crop that is easy to grow, easy to harvest, and allows you to use the root AND the leaves for cooking. Can you ask for much more? You can bake them into chips, stir-fry them, throw em’ in soups, shred them in a salad, and use them to dye your shirt red!

Here's my favorite recipe:

Beet and Carrot Salad

3 beets (medium size)
2 carrots (large size)
1/4 cup walnut pieces (optional)
Olive oil
Balsamic vinegar
Salt, pepper to your liking
  1. Shred beets and carrots in food processor or with hand shredder (better workout, I prefer this!)
  2. Drizzle Olive oil (1tb) and Balsamic Vinegar (1.5 tsp) and mix up.
  3. Taste, add more olive oil or balsamic to your liking
  4. Taste again, add walnuts on top, a dash of salt and pepper if needed.
Enjoy!

Apples are a classic ingredient and metaphor.  Apples are beginnings. A picture of a rosy apple launches our education as we innocently recite the alphabet in kindergarten. Apples are desire. Their temptation supposedly pushed Adam and Eve out of the first documented food forest. They are a choice between wholesome apple pie or sinful cider. An apple a day keeps the doctor away. But, don't follow in Snow White's footsteps...avoid poisoned apples. And, doesn't a bushel of apples buy security?

The other day, I was walking through Samuel P. Taylor State Park. Imagine redwoods and voluptuous ferns. We followed a winding path that saddled up to a stream. Using the first permaculture principle of observation, I spotted one, two, three apples on the forest floor. I turned this way and that. Was there an apple tree nearby? No, no, a hiker must have dropped his snack. But wait, way above, fifty feet high or more, were branches laden with apples. Fifteen feet away was a second tree. They were robed in swampy grey moss; their bark was rugged and worn. Recognizing their great height, I surmised these apple trees must be more than a century old, perhaps dating back to the paper mill that once churned nearby.

The apples were not quite so sweet as candy. They possessed a slight tang. I laughed. Who would have thought to find apple trees in a grove of redwoods? However, apples are pioneers of our imagination and settlements. Apples have adapted to fit particular purposes and places.

Hayes Valley Farm Permaculture Bootcamp graduate and San Francisco resident Ann Liska decided to "grow her own" and "build her own" ... soil that is. Watch the slideshow below to see how she "sheetmulches" by bringing layers together to build soil and grow food in her own San Francisco backyard.

Are you building soil? Are you growing your own food?
Please OH please tell us your story by adding a comment to this article.

On Thursday, a Hayes Valley Farm volunteer and Permaculture Bootcamp graduate turned their passion into productive power. Wes Frey, in a matter of hours converted trash destined pallets into a beautiful throne which will comfort and provide a relaxing resting space for many members to come. 

Want to get inspired to make your own furniture from pallets? Check out our pallet construction pictures and other inspiring pictures.

Got an idea for how to turn garbage into gold? Come on out to our site and let us know during one of our volunteer days every Thursday or Sunday!

As we look forward to our inaugural Dusker this Friday, August 27, we thought it might be good to talk a little about how the greenhouse and its setting attempt to reach beyond the basic 'performance' metrics of the job description 'Greenhouse'  and suggest a potential evolution in the contemporary models of both 'public space' and 'urban farm'.  To keep it short here, we can invoke the Philadelphian Louis Kahn and his concept of the 'three publics'.   Urban design, Architecture, and even the more current disciplinary rubric of 'Landscape Urbanism', each remain distinct from Art, per se, in that they have an explicit obligation to serve more than just the sensibilities of the artist.  Kahn's argument is that there are in fact three 'publics' that one ought to consider.

Preserve, pickle, jam, can, put up, ferment, jar.  These words have been occupying my thoughts for over a year now.  I have a great fascination with learning methods to make lasting supplies of food.  While this passion tends to fuel jokes about me from my friends, I know I am not alone.  A few months ago, I got together with some friends from the farm to learn how to preserve lemons.  Nearing the end of lemon season, we harvested an abundance of fruit from a friend’s Meyer lemon tree.  I was so excited to see the amount of what we had gleaned, an old recycling container half-full of fresh Meyer lemons that we would enjoy through the next coming months!  This is how we stack functions: through harvesting what would have been a surplus of fruit, we turned the fruit into lasting food instead of allowing it to go into the waste stream, and we reduced the possibility for pests to be attracted to the fallen fruit.  We also learned self-reliance by using an ancient and timeless method for preserving lemons through a memorable experience.   It was so easy; the lemons can be preserved for several months in their own juice with the addition of salt.

Sheetmulching is an example of biomimicry. What is biomimicry? ... It is the examination of nature, its models, systems, processes, and elements to emulate or take inspiration from in order to solve human problems sustainably ("Biomimicry", Wikipedia, 2010). After observing how nature (mainly forests) have built soil for the past 55 million years, we decided to mimic the soil building strategy. This begins the explanation of sheetmulching.

So why build soil? ... Well, currently humans are using an estimated 83 billion tons of soil per year. That's about 2500 TONS of soil per second. Which you can imagine as filling a football stadium parking lot with trucks, all full of soil. Then having those all disappear every SINGLE second. In short, we've got a lot of work to do in order to get to "sustainable" agriculture stage. However, if each one of us did just a little bit, built just a few yards of soil each year, we'd be back to an abundant and fertile planet in no time.

Look at the above picture, you'll notice multiple layers right? Well, that's exactly what were doing, combining multiple layers together in order for them to decompose into a rich, healthy and bacterial diverse soil.

General Recipe

  • Top Layer - Finer wood chips, mulch or dried leaves, - 2 - 6 inches, woodchips are free from Bay View Green Waste in SF
  • 2nd Layer - Green matter - 2 - 6 inches, manure, grass, veggie wastes
  • 1st Layer - Cardboard / newspaper - 2 inch to 6 inches deep
  • Bottom Layer - The Ground, if it's compacted maybe use a digging fork to loosen it up a bit for moisture penetration 

Sheet-mulching is a technique to build new, fertile soil. Cardboard is laid down to cover ivy and weeds and suppress their growth. It also prevents soil disturbance, absorbs water, and retains moisture. We then add layers of manure and mulch 3 or 4 feet high. Lastly, we plant fava beans and clover to fix nitrogen in the soil, to balance out the carbon-rich cardboard and mulch. As the manure and mulch transform into new soil, the cardboard and breaks down. 

Hayes Valley Farm Soil Building Stage 1

During the first 3-6 months we have began the soil building strategy with this formula... it may vary depending on your local climate, available waste resources and soil type.

  • Nitrogen Fixing Legumes - Fava Beans, Pigeon Peas, and other leguminous plants, plant directly after sheet mulching after coating them with rhizobium bacteria.
  • Nitrogen Fixing Ground Cover - New Zealand White Clover
  • Sheet Mulching - read above recipe
  • Ground - usually covered with ivy, or heavily compacted soil

Turn in beans before they start fruiting for maximum nitrogen fixation and after 6-12 months and soil will be fully composted. Best time to sheetmulch is in the fall before the rains(in mediterranean climates), or in the spring (in climates that freeze).
