Bay Area Butterfly Festival Lands May 19

By Annina Puccio, executive director of the Monarch Milkweed Project

The Monarch Milkweed Project and the Vallejo People’s Garden are hosting the inaugural Bay Area Butterfly Festival on May 19!

Join us and experience the beautiful view of the Carquinez Strait from the boardwalk on Mare Island while learning about the importance of protecting our pollinators. This is a family-friendly community festival!

On two stages, fantastic performers and live bands will delight you with their talents. Children’s free games and hands-on activities will entertain young ones throughout the day. Musical performances will fill the air — dancing is not required, but it is definitely recommended! Artisans and small businesses will sell their art, wares, and many fantastic sustainable goods.

On a third stage, community groups will lead pop-up workshops on a wide range of exciting topics, which will include a talk sponsored by Sustainable Solano by Heath Griffith of Grow With The Flow on how to turn your lawn into a native garden. Food vendors and food trucks will offer a variety of cuisines, including vegan and gluten-free options.

We will be hosting over 100 vendors/exhibitors from various organizations and nonprofits at the event. There will be a focus on sustainable living, clean water practices, and environmental education.

This festival is a low-to-no-waste event focusing on commemorating the historic monarch overwintering site on Mare island, as well as the importance of sustainable practices and saving our pollinators — especially the iconic monarch butterfly and our various native bee species.

Testing Your Soil: A Toolkit for Gardeners

By Patrick Murphy, Program Manager

Soil testing is an accurate and definite way to get an idea about how your soil is doing and learn what issues you might be dealing with. But what type of tests are there? What information are you looking for? How do you determine which test is best? You may want to follow a “Learn. Test. Act.” approach. Learn about the site’s history, test your soil appropriately, and act upon the test results.

Learn about your future gardening location — The test you choose depends on the history of your site. Solano County was incorporated in 1850, and the county has seen a variety of industries come and go. As such, many possible urban agriculture sites lack a robust history. Do your research before you begin:

  • What used to be near this garden space?
  • What possible sources of contamination are there?
  • What will you be growing?

You may wish to contact the local museum, or check out some online sources (see our toolkit for some suggestions) to learn more about your site’s history.

Test your soil appropriately — A variety of tests are available to everyday people and many are fairly inexpensive. The most accessible type of test is probably a “nutrient panel” (often called a “soil paste” test), which gives you an idea of the nutrient content of your soil. This will give you a breakdown of each nutrient, soil pH, salinity, etc., depending on the lab and exact type of test. You can learn more about what needs to be addressed in your garden (e.g. a lack of nitrogen, too high a pH, etc.).

The other common type of test would be some variety of heavy metal test. It is important to consider the variety of plants and produce you plan to harvest. Leafy vegetables (lettuce, kale, spinach) are known as hyperaccumulators and draw heavy metals up into their leaves. A key property of many leafy greens is their ability to accumulate heavy metals in their tissues without the traditional signs of toxicity. Do not assume plants will “reject” contamination; a significant number of plants humans consume can accumulate heavy metals in their edible areas. If you are concerned about heavy metals, such as lead and arsenic, you should test the soil you plan to grow in.

Primary Pollutant Metals-13 (“PPM-13”) and the California Administrative Manual-17 (“CAM-17”) are the standard tests to determine if you have heavy metals in your soil. PPM-13 looks for the 13 most common heavy metals, CAM-17 for the 17 most common. Either of these tests are perfect for locations where you believe there is a chance of heavy metal contamination. Additional tests exist to determine if soil has been contaminated with things like DDT, gasoline, etc. For more information about tests and costs, check out our soil contamination toolkit, or consult an environmental health specialist.

Act with the information you have — Once you have your results, decide what to do. You may have perfect soil that requires only that you begin planting. If you discover you do have a significant level of soil contamination in your garden space, you may want to consider alternative locations, remediation methods, or some combination of both. There are a number of good resources from agricultural offices and university extension programs, some are linked in our soil contamination toolkit. Always make sure the remediation technique you’re using is safe, effective, and observable. If you are attempting remediation, you will need to test your soil at regular intervals to evaluate how effective your efforts have been.

At Sustainable Solano, we have selected two potential sites that we plan to test over time to not only see what the soil composition looked like at the start of our work on these gardens, but also how our approach to building healthy soil and using permaculture practices affect the ongoing health of those gardens. We look forward to offering future updates on what this “Learn. Test. Act.” approach yields.

2024 Benicia & Vallejo Demonstration Food Forest Garden Tour: April 27

By Nicole Newell, Sustainable Landscaping Program Manager

Loam Sweet Loam garden in Vallejo

Sustainable Solano’s annual tour of demonstration food forest gardens in Benicia and Vallejo returns on April 27 for its eighth year. Join us for our largest tour of some of the longest-established food forests in the county!

The day will include speakers and activities to keep you inspired and engaged. Register here!

We will start at 9 am at Avant Garden in Benicia with a talk about the many roles mulch plays in supporting a water-efficient garden with Heath Griffith from Grow with the Flow. Learn about:

  • What is the difference between wood chips and bark?
  • Why is mulch one of the superheroes of permaculture?
  • Does mulch increase or decrease fire risk around houses?
  • How does mulch support a water-efficient garden?

Attendees will pick up the itineraries from 9-11 am at Avant Garden for a self-guided tour of the Benicia and Vallejo gardens. This year’s tour will continue to provide education on topics related to sustainability and highlight the amazing organizations and ways people are involved in uplifting the community. In addition to education, we will also have music, an adventurous scavenger hunt for our youth, two inspired gardens and a special guest that will be present to chat about calming calendula.

The Benicia gardens will be open from 10 am-1 pm, and the Vallejo gardens will be open from 1-4 pm. Attendees who can only participate in the afternoon can pick up the itineraries for Vallejo at the Pollinator Pathway garden on Mare Island from 12-1 pm.

You can learn about each garden and the special events going on at the gardens here.

To prepare a garden tour event that is in service to our community is a gift. As I learn what inspires our food forest keepers to live, grow and contribute, I am inspired in return. Spring brings new possibilities to discover what seeds we want to plant, in our garden and in our life. Each garden serves so many functions that support an abundant, healthy life. I invite you to explore these gardens and gain your own inspiration for your gardens, your communities and your lives.

This program is made possible by the generous support from the Solano County Water Agency.

Benicia Demonstration Food Forest Gardens

The Curious Garden

Mature front yard food forest has mostly fruit trees and native plants that attract pollinators year-round. It has a laundry-to-landscape greywater system.

The homeowner started gardening while living in San Francisco, and took a semester-long Garden for the Environment class on all aspects of gardening including permaculture. The family moved to Benicia about 12 years ago, partly so they could have space to grow a garden.

The family has enjoyed growing their own food and exploring the changing yard and the wildlife it attracts. It also has a very steep hill, which presents its own unique issues — and a great canvas for growing yellow lupine among the other native plants.

Giardino su una Collina (Garden on a Hill)

A 4-year-old food forest and pollinator garden installed in 2020 that includes a swale that captures roof water and mediterranean trees and plants mixed with native pollinating and nectar plants to attract bees and butterflies. This site is home to a Monarch Waystation that grows a variety of plants to support Western Monarch Butterflies.

The Monarch Milkweed Project and monarch education will be highlighted. Come to learn how you can support and participate in the Bay Area Butterfly Festival coming to Mare Island on May 19!

Greyhawk Grove

Greyhawk Garden after installationA 9-year-old established food forest with two swales that are dug out and refreshed every 2-3 years, laundry-to-landscape greywater to fruit trees, and chickens. The drip irrigation system was removed four years ago and the garden is thriving! Annual beds are hand-watered once a week during the growing season. Greyhawk Grove is a “high-traffic-survival-of-the-fittest-have-three-young-children garden”. There may be lemonade and baked goods for sale by children, as well as products from the garden to give away (dried calendula, lavender, herbs, eggs, fruit, etc.).

Yggdrasil Garden

An evolving food forest garden and greywater system installed as part of Sustainable Solano’s 2022-23 Permaculture Design Certificate course. Students transformed the front yard with a rain-capturing swale and planted berms in holistic workshops. The west side yard’s raised vegetable bed and passionfruit vines are watered by a laundry-to-landscape greywater system and include edible plants and native pollinators. The monarch butterfly-hosting back gardens are designed and maintained by permaculture designer Michael Wedgley’s Soilogical, nurtured with specially prepared compost, and supported by Seth Wright’s Water Service Irrigation design created as part of a Sustainable Solano irrigation class. An herb spiral was created with bricks repurposed from the chimney of the circa 1850s historic home, retaining walls from pieces of historic on-site stables, and patios from slate and brick on-site. The east side yard (in development) is watered with both a rain-capturing swale and a laundry-to-landscape system and will have an aquatic garden and feature scented contributions to the edible landscape. Displays feature the historic aspects of the home; its background and ongoing tradition of art, design, and healing; information about the Ohlone Sogorea Te Indigenous Land Trust and rematriation of Carquin land; and the garden’s first tree guilds: persimmon, apricot, fig, passionfruit guava, and meyer lemon.

There will be a water harvesting guided tour with designer Michael Wedgley from 10:30-11:30 am, and PERSONA will perform live acoustic pop/R&B songs from 12-1 pm.

Inspired Garden

This homeowner attended our tours and was inspired to transform his yard! This garden, designed by Michael Wedgley of Soilogical, is a unique opportunity to tour a stunning and sustainable backyard that showcases the beauty and abundance of permaculture. This eco-conscious backyard features a rainwater catchment system that can harvest up to 3,500 gallons per year, helping to restore the on-site water table, and providing an abundant source of water for this permaculture food forest.

The carefully designed irrigation system utilizes drip irrigation, which not only lowers water usage but also promotes water conservation. This 1-year-old garden boasts over 80 different species of perennial plants, many of which are edible. You’ll be amazed at the variety and richness of the plants that are flourishing in this environment.

Vallejo Demonstration Food Forest Gardens

Colibri Ochoa (Hummingbird Ochoa)

Front yard food forest garden has a laundry-to-landscape greywater system, a swale, repurposed logs to create planting areas and a variety of plants to provide food for people and pollinators. On the day of the tour there will be a laundry-to-landscape greywater education in Spanish and a translator on-site.

Sustainable Solano partnered with two other organizations to install this garden in 2021 and begin to provide resources in Spanish. Planting Justice partnered with Sustainable Solano on a Spanish-speaking installation. They offer permaculture services and also have an organic nursery in Oakland that sells rare and heirloom varieties. Club Stride translated an educational program about Patio Sostenibles and created a food forest video in Spanish, Entrevista de Patio Sostenible. Both organizations are doing incredible work to reduce inequities. Check out their websites to find out more on how to support their work.

Inspired Garden (Sure-Would Forest)

The homeowners had a nearly blank slate when they purchased this property in 2021, and soon started working on enriching the soil, retaining rainwater, and laying the groundwork for a food forest. This garden was inspired by Sustainable Solano gardens and a love of fresh fruit. In just over two years, they’ve gone from food desert to food forest with the ability to eat from their garden year round. They attended a design class taught by Joshua Burman Thayer with Native Sun Gardens in 2023 through Sustainable Solano’s backyard program. In June 2023 they hired Joshua to update the design and add drip irrigation.

Inspired by rainwater harvesting systems seen on the 2023 demonstration food forest tour, the homeowners bought and installed four IBC totes to collect water from their downspouts. The irrigation system for Sure-Would Forest is designed to feed from either city water or rainwater storage tanks, allowing over 1,000 gallons of rainwater to be used to irrigate the garden.

At 2 pm, the homeowner will talk about how he converted IBC totes to capture water and irrigate his garden.

We are incredibly grateful for the generous support of our funders. The first seven food forest gardens were made possible through funding from the Benicia Sustainability Commission; the Solano County Water Agency continues to support the Sustainable Backyard Program throughout the county.

The Vision for a SuSol Education Center

By Sustainable Solano

Sustainable Solano has had a vision for a while now: To have an office space that serves as a place of education around the many things we teach about, such as sustainable landscaping, water capture and reuse; cooking with seasonal, sustainable local food; and building community resilience.

We have been lucky to spend the past few years in our office at the Global Center for Success on Mare Island. This office space puts us near nonprofit partner organizations and the beauty of the Vallejo People’s Garden and the Pollinator Pathway garden we installed with them and Solano RCD in front of the building. But as our team has grown in number, we find there are limitations in a one-room office, both for our team members’ needs as well as ways we would like to interact with all of you in the community.

And so we are returning to that original vision.

We would love to find a safe and beautiful place where we can create and exhibit the solutions we’ve been teaching and demonstrating for nearly 25 years. These may include a permaculture garden or farm, sustainable water techniques, solar energy and maybe even chickens. There could be a commercial kitchen space for teaching classes and preparing food (or the potential to add such a space). We also need a shared workspace and a place to gather around a table for large team or partner meetings, and an area to house tools and equipment, promotional materials and office files. The property would need to be zoned to allow for office space and would need to be able to support visitors coming to the site for meetings, classes and demonstrations.

We’ve seen creative and innovative ways individuals, organizations and cities have supported such projects. In Berkeley, the Ecology Center runs EcoHouse, which was founded in 1999 when a group of individuals “collectively purchased and transformed a small, dilapidated North Berkeley home into a demonstration house and garden.” In American Canyon, the city offered up an old public works yard to be transformed into the Napa River Ecology Center in partnership with the American Canyon Community Parks Foundation. Santa Cruz Permaculture now stewards a 26-acre farm under a 30-year lease as part of its operations.

We’d love to hear your ideas and suggestions for supporting this vision! Reach out to us at info@sustainablesolano.org

Even with this active vision for an education center, Sustainable Solano is committed to continuing hands-on sustainable landscaping and resilience-building workshops, cooking classes, and internships within Solano communities, because these are the very heart of our work. Our goal is to bring neighbors together in ways that help them connect with each other, the Earth, and themselves.

How to Compost at Home

By Patrick Murphy, Program Manager

Backyard composting often feels like a hobby reserved for those “in the know.” Like sourdough starter and beer brewing, the process seems both too simple and too complex to get started. How do you get from wheat and water to become bread? How do you turn yard waste and food scraps into compost? The answer is planning and time (and bacteria). With a little preparation and some patience, you too can compost your food scraps at home.

Composting requires a little forethought, some dedicated space, and the diligence to do regular light maintenance. If you can keep a houseplant alive, you should be able to get a compost bin started. The most important thing with backyard composting is to choose a system that will work best for you, which you feel you can sustain long-term. There are two common options for at-home composting, “hot pile” and “vermicompost” (or worm bins).

A stereotypical “hot pile” composting system uses a large bin and regular aeration to convert organic materials (i.e. food scraps) into compost. This system works very well when it receives a regular supply of organic materials, and is turned often. However your pile will begin to work less and less efficiently if the bin ever has less than a full cubic yard of material in it. Hot pile systems require that you maintain a specific ratio of high-nitrogen/high-carbon scraps in order for the bacteria to break down the material. I would recommend these systems for larger families, or organizations looking to get into composting. Learn more about hot pile composting here.

A vermicompost system relies on worms to digest and process organic matter to create compost. These systems offer more flexibility compared to a traditional hot pile system. Vermicompost systems can be made in any size, allowing them to fit into more spaces (some people keep their bins under their kitchen sink). Vermicompost systems do require more careful planning than a hot-pile system. While worm bins do not need to be turned, bins need to be emptied more regularly and the worm populations need to be divided to prevent overcrowding. Worm bins also typically cannot be added daily: worms eat in “batches”, so waste needs to be collected and added all as a single, larger quantity. I would recommend worm bins for smaller families, or people who might lack the space or volume of material needed to start a hot pile system. Learn more about vermicomposting here. 

There are multiple options when it comes to composting at home, make sure you check out multiple methods and choose the one which you feel you’ll be able to maintain the easiest. Consider alternatives to compost like indoor bokashi fermentation, or an outdoor green cone digester. Compost alternatives allow you to avoid most of the emissions created by throwing away food scraps while still allowing you to return nutrients to the soil. Focus less on the total volume of compost produced, and more on ease of use for yourself.
