Permablitz & Community

March 8, 2019 by Myke Johnson Leave a Comment

As we plan for a new Permablitz season, I offer you some reflections about the Permablitz held at Margy’s and my house two years ago. (A version of this post first appeared in my blog, Finding Our Way Home.)

Over 20 people came to our yard and worked together on projects organized by the Resilience Hub. They installed rain barrels, built a composting system from pallets, built a fire circle, and created five more growing beds for future fruit trees, raspberry bushes, & hazelnut bushes, and one bed for flowers & herbs.  We also got the first shovelfulls dug for a pond.

Opening Circle-Sylvia, Cathleen, Ali
[Opening Circle]

At the end of the day, I felt teary-eyed with the sense of Gift.  The generosity of so many individuals coming together and creating something so beautiful and full, helping us to realize our dreams for this piece of land, was deeply moving.  There is something about this giving and receiving of human attention and wisdom and care, that feeds our hearts. Much of our lives are shaped by transactions—we pay a certain amount of money, and receive a product. Or, we put in so many hours and receive a paycheck.  But giving and receiving freely and generously touches something much deeper. Giving and receiving must trigger deep neurotransmitters in our internal chemistry, sparking a profound sense of well-being and belonging.

I also realized how many layers of community are involved in such a project.  One layer is this community of people who care about the earth, and who come together to give and receive, to learn, to share, to grow, to get to know each other.  People connections are made.

Another layer is the community of the soil itself.  During the blitz I was mostly working with several others on the project for creating new growing beds.  We were adding nutrients through sheet mulching so that the soil could create a thriving fertile community.  I have learned so much about the variations in soil communities from the book The Holistic Orchard by Michael Phillips.

What a food forest needs, what fruit trees need, is soil whose fungal community is stronger than its bacterial community.  In contrast, annual vegetables and flowers and grasses prefer soil with a stronger bacterial community.  A bacterial community is enhanced by tilling the soil and incorporating organic matter by turning it into the soil.  A fungal community is enhanced by no tilling, but rather adding organic matter on the top of the soil to decompose, as it happens in the forest. (Similarly, compost that is left unturned will generate a stronger fungal community.)

Forking the beds Cathleen

We prepared the soil by aerating it with garden forks–since it had been rather compacted.  We added some granite dust for mineral enhancement, then put down a layer of cardboard to kill grasses and weeds.

Raspberry Bed-manure & chaff Mihku & Heather

Then, we added chicken manure, coffee chaff, seaweed, leaves, grass clippings, composted manure, and a really thick layer of deciduous wood chips.  We were able to get a delivery of 8 yards of wonderful ramial deciduous wood chips–these are chips which include lots of thin branches, which have more lignin content that is not yet woody.  The wood chips are the most important part of enhancing the fungal community.

After-Fruit Tree & Flower/Herb Beds

We also made several pathways with cardboard and wood chips, and I worked to complete those bit by bit in the days after the blitz.  Wonderfully, the process then works on its own–we add some water or it gets rained on–and the microbes will work together over the next several months and years to create a thriving soil community.  We planted trees and bushes the following spring.  My friend Roger Paul said that the Wabanaki word for “soil” means giver of life.

I encourage you to consider participating in a Permablitz to experience this sense of community for yourself!

2019 Permablitz Work Parties – Call For Hosts

February 15, 2019 by Kate Wallace Leave a Comment

It’s permablitz planning season and you’re invited!

•Are you part of a community group that could benefit from increased access to your own fruits and vegetables? From reduced water or electricity bills?

•Are you an organization doing community organizing or direct support work that has an idea for the way that small-scale energy or food/medicine production could support your work?

•Are you a tenant or a renter in an urban area wanting to increase your access to fruits and vegetables, decrease water or electric bills, and learn about and demonstrate urban gardening techniques?

•Are you a property owner in a rural, urban, or suburban area looking to build your household’s resilience and also committed to building equity in your community by leveraging your property towards community benefit? (This could look like land sharing agreements, building a community gathering space, creating a neighborhood food distribution network with surplus, running a community research project on soil remediation, etc.)

The Resilience Hub is seeking proposals for projects to build community-scale resilience for this year’s season of permablitz work parties! To apply with your idea for hosting, fill out this form!

The Portland Permablitz Network organizes work parties to build projects that increase resilience through backyard or neighborhood food production, energy generation, water catchment, and community-building. We take a permaculture approach – a way of designing that mimics nature’s patterns. Together, we can accomplish in a day what it might take an individual or small group a whole season to complete. We will convene 5-6 permablitz work parties from May through November this year.

Do you know groups or individuals that might be interested? No permaculture experience necessary! Can you pass the word along?

To apply with a proposal for hosting, fill out this form by April 1!
Please contact Kate at kate@resiliencehub.org if you have any questions. Thanks so much!

Hail to the 1 Percent

January 15, 2019 by Matt Power Leave a Comment

Are we Sheeple, or people?

You may not know that the Resilience Hub (aka Portland Permaculture Group) is one of the largest meetup organizations in Maine. With 2,933 members, the only group I could find that’s larger is an “outdoor adventures” group.

Which brings me to our current effort to raise money to keep the Resilience Hub alive. So far, 34 members have donated. That’s 1.15 percent of our membership. We’re extremely grateful to have this tiny, but loyal group willing to show their support in a real way, but it’s a pretty shocking statistic.

Think about some non-necessity you spent $5 bucks on this week (I know, it’s hard to think of anything that inexpensive). Perhaps a mocha latte, or a bottle of wine, or a pint of Ben & Jerry’s ice cream. Now imagine instead that you had taken 5 minutes to send that $5 to the Resilience Hub online.

It 2,933 members did this, we would raise almost the entire $15,000 fundraising goal set by the Hub!

And instead of empty calories, what would you get for your money?

How about hundreds of like-minded friends, access to instant garden and herb expertise, kombucha-making workshops, pruning workshops, grafting workshops, mushroom-growing workshops, permaculture design courses, and a path that puts people first, not corporations.

The billionaire Koch brothers—the other 1 percent, spend hundreds of millions of dollars underwriting their bleak vision of our future: exploitation of ecosystems, dismantling what little affordable healthcare we still have, and tearing up protections for women, labor, civil rights groups and retirees. No wonder they often seem to be winning.

Isn’t it worth just a few bucks to make sure The Resilience Hub is here tomorrow, bringing skills, food and real “resilience” to our lives?

Please DONATE now.

Let’s show the 1 percent that we believe in an abundant future.

Urban Leaves: Free, Plentiful, and Laced with Lead

December 12, 2018 by Matt Power Leave a Comment

City leaves often contain heavy metals, so compost with care.

A few years ago, I heard Maine farmer Will Bonsall “go off” in praise of leaves as a natural and free form of compost, better, he claims, than almost anything else you can buy in a bag. But he was talking about leaves acquired on or near his rural farm, not the ones raked off of city lawns.

Mixed Blessing. Although rich with nutrients, urban leaves can also be high in lead and aluminum. Source: Chemical Composition of Municipal Leaf Waste and Hand-Collected Urban Leaf Litter

I’ve been using about 100 bags of leaves as compost every season, collected from curbsides around Portland, where the locals conveniently rake it up and stuff it into paper, biodegradable bags.

What could be wrong with free, easy to access (often pre-shredded) leaves? Unfortunately, there’s a catch. (Isn’t there always?)

While reading an obscure book written in 1870 praising the use of “muck” by southern farmers (their term for half-rotted leaf mold), it ocurred to me that use of leaves in rural and urban settings shouldn’t be assumed to be equally virtuous.

The Lead Problem

In many areas of Portland, for example lead levels in soils are hundreds of times higher than “safe” levels, as determined by the EPA. I know this from samples I have had tested. Certain areas are worse than others, of course. Prior to 1978, most homes were painted repeatedly with lead-based coatings. Any house in Portland older than that likely STILL has lead content in the paint, the plumbing or elsewhere.

Lead doesn’t dissipate much on its own, so our soils are heavily afflicted with it. The older and denser the region of town, the higher the likely lead (Pb) content.

Back to my point about using leaves as mulch. Are they safe? Do they pick up heavy metals such as lead?

The answer, according to a study done in New Jersey on municipal leaf mulch, is yes, (unfortunately).

Researchers  found numerous metals in curbside leaves, including lead,  iron and aluminum. They suggest that this occurs because the fallen leaves “become contaminated with urban soil and dust from the road surface through various processes (raking, lawnmower pickup and vacuum) used for litter collection in the yard and at curbside.”

Of the various contaminants, lead is arguably the most concerning. How bad is the potential pollution in city leaves? They apply a standard of 45 Mg/ha, based on tests of sewage sludge–which equates–by my calculation, to about 45 tons of leaf matter spread on 2.5 acres of land.

Break that down to the garden plot level.  An acre is 43,560 sq. ft. If you were only adding this much material to your beds, you would add about 1.21 lbs/sq. ft  of leaf compost per year (108,900 sq. ft, divided by 45 tons/90,000 lbs.=1.21 lbs. per square foot).

Given this level of application, lead levels in your garden would not exceed the EPA rules for “annual pollutant loading rate”–at least for a few years.  In the worst case scenario, with the highest level of lead contamination the researchers found in leaves, an application of this much leaf matter would take 16 years of repeated use to exceed EPA levels.

Don’t get too relaxed, however. If you’re like me, you add significantly more leaf mulch than that to your beds.

Let’s say you have a 4 ft. x 20 ft. garden bed. At the intensity of leaf mulching suggested by the researchers, you would only add 96.8 lbs. of material to the bed (80 ft. x 1.21 lbs/sq. ft.). But I’ve often added many times that much free leaf mulch to my beds at the end of a season, haven’t you? A yard of compost weighs between 1,000 and 1,600 lbs., depending on water content. That means that if I happen to apply what amounts to a yard of highly contaminated (at the worse end of the scale) curbside leaves to my annual beds, I could exceed EPA safety levels for lead in my garden in less than two years. And this assumes that we can trust the EPA guidelines are strict enough, which is a matter of some debate.

What to Do Now?

All of this is incredibly frustrating of course. Human beings somehow seem to turn the most benign sources of natural abundance into new forms of poison. We’re encouraged to buy our way out of the problem, paying exhorbitant amounts for “clean” compost products in 80 lb. bags. What a racket! It’s not unlike what’s happening with our water supplies. We’re forced to either buy bottled water or install an expensive filter if we want to drink clean water.

So let’s not give up on urban leaf compost. We just have to be more strategic in where we obtain it. And also, here’s one caveat: If the leaves will be used in a garden that is strictly ornamental, you’re probably safe to use as much urban leaf material as you like. The lead levels are probably too low to be of concern for pets or casual contact. I would mainly be concerned with gardens used for food production. The details matter. Certain plants, such as berries and fruit trees, for example, are unlikely to draw lead contamination into the fruit. But other plants absorb lead like crazy, especially in their roots. Brassica nigra, or Black Mustard, is a good example. Mustards seem especially good at extracting lead from soils. So are sunflowers.

Where I would take special precautions, however, is with the introduction of urban leaves to  annual gardens where cabbages and leafy greens are grown for consumption.

Here are my suggestions for reducing the risk to your health and your soils, while still using urban leaf compost:

  • Avoid gleaning from the old City. In Portland, for example, I would not use leaves gathered on the West End or Munjoy Hill, nor in Bayside, for that matter. A lot of the debris from the great fire of 1866, for example is buried in Bayside, and these “historic” areas are often toxic wastelands in terms of the lead contamination of the soils.
  • Look for natural lawns. Much as we’d like to see all lawns replaced with permaculture gardens, that’s a long way off. In the meantime, gather leaves from homes with heavy grass cover that doesn’t look like herbicides have been applied. The grass reduces direct contact between leaves and soil.
  • Favor new developments. Scout out new developments  on the urban fringe, where homes were built after 1978. I suspect someone has a map of Portland with an overlay based on the age of the neighborhood. If so, post it here in the comments please.

Sorry to be the bearer of bad tidings about urban leaves. I wouldn’t take them off your list of permaculture resources. Simply be more selective in where you acquire them. Head for the outer suburbs, and be careful about buying your mulch from organizations that use urban leaf compost as a major component of their mix.
