freeway food forest potato towersAs part of our Hayes Valley Farm Earth Day festivities, site designer and educator David Cody lead a hands-on tutorial in DIY potato towers. Once we learned the basics, a crew of us built more than a dozen towers for our rapidly growing Freeway Food Forest.

Potato towers are vertical structures that provide a practical, no-dig, high-yield way for folks to grow and harvest potatoes in limited space. What do potatoes towers have to do with Earth Day? Potatoes are a high-calorie crop, which means they can feed a lot of people while using little of the earth’s resources. They’re also a great way to build soil. Potato towers = earth care, people care, and fair share!

To make a potato tower:

Get a roll of three-foot-wide chicken wire (or “poultry fencing,” as the more avian-inclusive folks call it these days) and wire cutters. You’ll also need some soil, or if you don’t have soil, use mulch and horse manure, as we do at Hayes Valley Farm. If your soil or mulch is fine, you should have some newspaper on hand to line your tower. You may also need a shovel to load your tower, or just use your hands. Lastly, you’ll need seed potatoes, 20 to 30 per tower. You can either get a bag of potatoes from the grocery store, or you can order seed potatoes from a seed catalog. Seed catalogs offer a wide selection, and their potatoes will be less prone to disease.

Why do you need potatoes to grow potatoes? Potatoes are tubers, which are storage containers for starches, or plant energy. Tubers aren’t seeds themselves, but they can act as seeds when buried, using their energy to propagate a new plant. Those little growths, or “eyes,” you find on old potatoes are plant stems sprouting from the tuber.

Now, to build your tower:
  1. Cut a sheet of chicken wire four or five feet long. You want your tower to be a couple feet across so that it’s stable.
  2. Bend and fasten the ends of the chicken wire to form a tube.
  3. Find a nice outdoor spot for your tower, ideally against a wall or planter that it can lean on if it needs to. It should be in a place with sunlight and water access and drainage.
  4. Tear the newspaper into wide strips to bed the bottom of your tower. This will prevent your soil or mulch from leaking out the bottom and sides of the towers. If your mulch is doesn’t leak through the cage, such as leaf mulch, you can skip the newspaper.
  5. Shovel in five or so inches of soil, or mulch followed by manure.
  6. Plant about five seed potatoes in a layer, evenly spaced. Don’t plant cut or diseased potatoes.
  7. Continue layering newspaper (if needed), soil or mulch and manure, and potatoes until you get close to the top, ending with a layer of soil. Your seed potatoes should be well buried, so they aren’t exposed to light.
  8. Irrigate your potato tower by watering directly into the soil. You’ll want to saturate the tower, but don’t overwater. Water once a week or as needed.
potato towersWatch your tuber tower flourish! As the seed potatoes start to sprout leaves out the sides and top of your tower, they will also form underground stems and new tubers, about 4 to 8 per seed potato. Your crop of potatoes should be ready in about 90 to 120 days, depending on how big you like your potatoes. Watch for when the leaves start to yellow.

To harvest, pull up the wire cage or knock it over, and let the soil and spuds spill out. Root around for the potatoes, being mindful not to bruise or cut them. Compost any potatoes that are damaged, as they will spread disease. Store your potatoes in a cool, dry place, out of the sunlight.

On Saturday, April 17, nineteen people visited Hayes Valley Farm, including special guests from DrupalConSF. We started the day with a site tour where the group learned urban farming strategies such as building soil from the local waste stream, managing dwarf fruit trees with multiple grafts and pruning techniques, and solutions for potential soil toxicity including thick organic mulches, container gardening, and soil and leaf testing.

We also planted 30 lettuces into the east-facing berms of the old freeway on-ramp amongst the favas and clover.  The group likened the sharing of techniques at the farm to the sharing of code in the open source community, and mentioned how Hayes Valley Farm relates to some of the projects they are currently working on.

This past Tuesday April 6th was an exciting day for students and interns alike at Hayes Valley Farm. The farm was graced with its first ever group of youth from Presidio Hill School, a co-educational independent K-8 school located in San Francisco’s Presidio District. The visit was coordinated with the help of HVF Volunteer Allie, who leads the After-School Program at Presidio Hill, as well as HVF activist/organizer Booka and Garden Educator Intern Casey.

Nine children, ages 5-9, and three adults arrived to the farm at 11am to begin their day of holistic education. Blue skies and a pleasant springtime breeze brought smiles to the faces of all. Introductions were in order, as were blue-tape nametags in line with our farm tradition. The group formed a circle and played “Name Yourself and Your Favorite Fruit or Vegetable” which solicited delicious responses like artichokes, tomatoes, and persimmons. On to the farm tour, where the group was led up the south side off-ramp from coconut coir hill to sheet mulch heaven. The curious youth loved touching the various soils and discerning their differences, which led to great Q&As surrounding soil building, organic fertilizers, and nutrient solutions.

The farm tour ended up at the Freeway Fruit Forest where the educators explained the purpose behind container gardening and companion planting, as well as our intentional selection of San Francisco specific flora. The group gazed in awe down below at Fava Bean Hillside for an enlightening lesson on nitrogen fixation, or in kid terms, the bright greens giving back. Fava beans are a great tool to help us reinforce the connectivity of all living things.

The team moved on to a collective brown bag lunch followed by a composting exercise and hands-on worm bin maintenance. The kids loved holding the squirmy wormy invertebrate- Who wouldn’t? They coupled the interactive worm lesson with coloring images of worms to be laminated and stuck to the worm bin itself. This way, the artistic impact of the kids will live on at the farm.

The final hour at the farm was comprised of hands-on planting and button making, two activities that provided the kids with take-home goodies to cherish in the days to come. They were given small plastic planter pots to sow their legume of choice, either Blue Pole Beans or Scarlet Runner Beans. Their homework- to water, watch, and wait 60 days for their bean to sprout. And for the buttons- Each kid decorated his or her very own Hayes Valley Farm seal which was magically transformed into a 3” badge and served as a memento of their amazing inaugural visit to Hayes Valley Farm.


I live in the neighborhood, and I was excited and intrigued when I saw little “Hayes Valley Farm” signs appear on the chain-linked fences a few months ago. I showed up for some Thursday work parties and joined in the sheet-mulching fun, picking up pearls of permaculture wisdom from David Cody while getting some interactive, outdoor exercise. I was drawn in by the easy camaraderie, the opportunity to be immediately useful, and the beautiful audacity of the whole project. But I soon wanted more Farm in my life, and since I lived nearby, I looked for a way to get a little bit into my daily routine.

So I showed up more. I learned more from Jay about the daily needs of the Farm - turning compost, making sure the fruit trees and starter plants had enough water, and checking the moisture level in the berms I had a tiny part in building during the preceding weeks. I discovered the challenges of moving a 200-foot hose (affectionately called Stumpfinder) around the site, and got satisfaction from discovering little tricks of efficiency. Sometimes I am able to come early in the morning, rolling out of bed and down Oak Street for a couple hours of peace among the fava plants. The afternoons are usually more abuzz with activity, and therefore present more opportunities to learn from my fellow farmers - always more fun than learning on my own.

Part of my joy with the Farm is seeing it grow, both physically and as a community. If you haven’t been by to check it out, I encourage you to do so. Talk to people about what they are doing, and tell people what you would like to do. There is something fun for you, whether your idea of fun is frolicking through the favas or getting a physical workout. “Have fun” is the only directive I have heard on the Farm, and it seems to be a mighty fine way to build a community.

For the last couple Sundays, I have spent some time volunteering at Hayes Valley Farm, a new community farm project at the corner of Laguna and Oak. This was the site of the Central Freeway ramp before the 1989 Loma Prieta earthquake. The city zoned it for residential development, but it has remained a vacant, derelict, fenced-off block of ivy, trees, and pavement for the last twenty years. The site was recently activated for community use as a urban gardening education center, sponsored by the San Francisco Parks Trust. Hayes Valley Farm is an interim project lasting two to five years, maybe longer, until the economy picks up and the city’s development plans are back on the table.

This week I was put on site beautification, which involved weeding and cleaning up the chain-link perimeter of the farm. As Hayes Valley Farm Project Director Chris Burley put it, we just want to keep the site clean and green, so that people will respect it. Cleanup involved tearing up ivy, thistle (ouch!), and other undesirables that had spilled over onto the sidewalk. It also meant picking up paper coffee cups, soda cans, beer bottles, syringes, bags of dog poop, and other signs of city life. A cigarette lighter. A dye packet from a hair coloring kit. The cut corner of a cereal bag. There’s something eerily post-apocalyptic about seeing these discarded pieces our lives incorporated into nature, tangled up in ivy, packed into mats of soil that have collected in gutters.

Currently, I'm living in the San Francisco Zen Center, just a block up the street, and as I picked up trash, I thought of American Zen icon Issan Dorsey. I recently read Street Zen: The Life and Work of Issan Dorsey, a wonderful book about someone who could, by all accounts, be considered a modern bodhissatva. Issan was a drag queen and junkie who became one of the original students of Shunryu Suzuki and, later, the founding teacher of the Hartford Street Zen Center. He also founded the Maitri hospice for AIDS patients. Throughout his life, he stayed close to the edges of mainstream society, and his caring presence touched everyone he met. His story is an inspiration, particularly for people seeking meaning in urban life. Biographer and student David Schneider writes:

Moving through his world, I don’t feel that order has been imposed rigidly, or in a clumsy attempt to make sense of things. He seems perfectly willing to go with your arrangement if you have one, or to let things shift as they do. Issan seems instead to be in love with the things around him, and to arrange them out of affection. He told me one about cleaning. ‘You don’t clean to make things clean, so much. You clean even if it’s not a mess. You just go around and make things look like somebody paid attention to them.’

Issan’s philosophy on cleaning has stuck with me, and it came to mind as I walked around the farm site, picking up cigarette butts, bits of glass, shreds of plastic bags. Waste management is an endless, and often thankless, task. There is always more trash, but it does us no good to dwell on that. And maybe it doesn’t help us to think of it as trash at all–such as the pile of torn cardboard that may have been used to pad someone’s sleeping bag, someone’s home. This debris could be incorporated into the sheet mulching project some other farm volunteers were working on just a few feet away. The scraps simply needed to find their place in the new site.

It is therapeutic to interact with an urban space in this way, especially when you have help. Some things I appreciate about farm work are the economy and creative engagement with resources, and the cooperative nature of the work. Bringing that sense of care to this abandoned lot feels like a way of reclaiming it from the city’s neglect, and clearing and blessing it for the life, groundwork, and joy that us soil-starved city folks will bring to it.


Symbiotic relationships exist between many organisms. The teeth-cleaning shrimp come to mind. A little underwater spa treatment would make anyone feel like a new animal. One lifeform needs the other to do its job or survive. Our beautiful bald berms needed a healthy dose of nitrogen, to complement our thick layer of carbon cardboard. Our job, as farmers, was to breathe new life into soil that had been robbed of a lot of its nutrients, by walls of thick ivy.  Our best solution for implementing the nitrogen cure: a healthy dose of water-resilient volunteers!

After the last few weeks of spreading cardboard and organic matter on the farm many people were wondering, what's next? What will be our first "crop" this Spring?


"#1 Helper" by Hayes Valley Farm

This week we had both little ones and big ones come to the site to enjoy the new community playground. The first little one, pictured above, put on his gloves quickly and got to work moving cardboard, filling wheelbarrows and pushing tonka trucks. The big ones, pictured below, spanned the gamut from creating amazing artwork to filling wheelbarrows of mulch like there was no tomorrow. One volunteer taught me the "quick method" to filling a wheelbarrow by tipping it on its side for the "first 2/3rds" then to "tip it up and fill it up" for the last bit. I love how each person can come to the site and interact in their own way, both claiming and reinventing age-old work in our modern surroundings.
