Benicia Food Forest, Pollinator & Community Gardens

Avant Garden

The spring garden tour will begin at 9 am at Avant Community Garden in Benicia with a Permaculture 101 talk from Anne Freiwald. She is an experienced permaculture designer and always inspirational! Anne Freiwald and Lydia Neilsen will teach this year’s Permaculture Design Certificate course that starts in August, so this is a great opportunity to learn more about that program as well. Itinerary pick up will be from 9-11 am. Sustainable Solano Board Member Maggie Kolk, a Master Gardener, will host a Master Gardener information table. Come with your questions! Also during that time, Benicia interns will be highlighting their final project with a local food tasting, seed planting, handing out a scavenger hunt for youth and more.

Bay Vista Homeowners Association

 In June 2024, Bay Vista HOA in Benicia transformed its common area lawn into a waterwise, sustainable landscape to reduce water and beautify the space.

Michael Wedgley from Soilogical was the designer for this project. A lot of consideration went into plant selection. It was important to provide plenty of native species for habitat and food for native insects and birds, while also considering aesthetics as a critical aspect in HOA common spaces.

The plants selected and water catchment from the roof downspouts to the in-ground basins makes the landscape more resilient and builds healthy soil.

Greyhawk Grove

Greyhawk Garden after installation

A 10-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. Water elements in the form of fountains were added last year, which lured in a wild (non-venomous) snake who can sometimes be seen lounging between flagstones, and a frog who can be heard at night. Special thanks to Solano County mosquito abatement for the mosquito fish who overwintered and continue to thrive in the fountains. Greyhawk Grove is a “high-traffic-survival-of-the-fittest” 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.).

Redwood Guild

Food forest garden and greywater system installed as part of Sustainable Solano’s 2021 Permaculture Design Certificate course, with students transforming the front lawn with rain-capturing swales and planted berms and converting the sprinkler system to drip irrigation. The side yard is watered by a laundry-to-landscape greywater system and includes edible plants and native pollinators. This home has its own redwood grove, and certain plants were selected that do well in the unique conditions created by redwoods. The food forest keepers are using that knowledge to add other plants to the garden that will thrive alongside the redwoods.

Wild Cherry Way

Southern slope food forest focused on pollinators, shrubs and native plants. This garden also includes fruit trees, perennial and edible plants, swales and a laundry-to-landscape greywater system.

***Sustainable Solano Board Member and Permaculture Consultant Ron Kane will be on-site to offer tours and answer questions.

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 with native and pollinator-supporting plants. The west side yard’s passionfruit vines and fruit tree guilds are watered by a laundry-to-landscape greywater system. The monarch butterfly-hosting back gardens were designed by Soilogical, nurtured with specially prepared compost, and supported by a Water Service Irrigation design created as part of a Sustainable Solano irrigation class. The site’s current steward, Heath Griffith of Grow with the Flow, cultivates edible landscapes with flowers and medicinal herbs, with an eye towards community engagement and ecological justice. An herb spiral was created with bricks repurposed from the chimney of the circa 1850s historic home, retaining walls were built from pieces of historic on-site stables, and patios were made 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. 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 various permaculture systems and landscape elements.

***Heath Griffith will be on-site to talk about permaculture, water harvesting, sustainable water use, and more! They participated in the 2022-2023 PDC and will be supporting this year’s PDC course in the fall. The garden will also feature kid-friendly hands-on activities and live music!

Vallejo Food Forest, Pollinator & Community Gardens

First Christian Church

The church has two separate gardens: one is a peace garden with mostly flowers, cactus and trees, and the other is the vegetable garden, called Johnson Ranch. The vegetable garden was revived through the Solano Gardens program. The food grown is donated to the local food pantries (Faith Food Fridays, Amador Hope Center, etc.).

***Solano Gardens Program Manager Parick Murphy will be on-site to share DIY Landscape Design templates for both edible and water-efficient gardens. He also will be highlighting opportunities to get involved with local community gardens and available to discuss interest in future community gardens within the county.

Loma Vista Farm

Loma Vista Farm is a program of the Vallejo City Unified School District. Students come to the Farm every week to participate in hands-on plant and animal science lessons.

The Farm is partnered with the Friends of Loma Vista Farm, a community-based nonprofit organization, which fundraises to provide all the expenses for the day-to-day operation of the farm, including all the animal and garden expenses, as well as major ongoing capital improvements.

This has been a treasured part of the community since it began in 1974. Families and individuals are welcome to visit on a drop-in basis during open hours and enjoy seeing the many animals and gardens. The farm is also a field trip site for schools and groups on a reservation basis from all over the Bay Area.

The Food Forest Garden provides a beautiful demonstration to the public on how they can plant their own yard in a variety of fruit trees, perennial vegetables, herbs, native plants and pollinator rich plants.

***This year’s tour is on the same day as Loma Vista Farm’s annual Spring Open House, making it an extra special day to visit. Plants that the students have grown will be available in the greenhouse for sale, animal feeding will be available, as well as entertainment such as a puppet show. For more information check out Lomavistafarm.org.

Morningside Botanical Bounty

Morningside Botanical Bounty food forest was created as part of the Resilient Neighborhoods Program. This backyard garden has a laundry-to-landscape greywater system, fruit trees (pruned to keep them short and easy to harvest), swales, drip irrigation, bee-friendly plants, native plants and shade trees.

It’s now the sixth year after the install and many of the plants are still thriving. The greywater system irrigates the bougainvillea and butterfly bushes, which are popular with bees and hummingbirds. The drainage from the gutters to the swale and hugel mound prevent the yard from flooding during the rainy season. The water is stored in the earth and is available to the trees, artichoke, and roses. The peach tree, selected to be a variety resistant to leaf curl, has provided fruit even in years when most other peaches in Vallejo fail. Once a week watering of the trees on site allowed them to grow deep root systems, and they haven’t needed irrigation the last two years.

Pollinator Pathway (Vallejo People’s Garden)

Pollinator food forest garden filled with a variety of California native plants that support the habitat of butterflies, bees, moths, wasps, hummingbirds and so much more. This garden was installed in February 2023 as a collaboration with a variety of organizations including Vallejo People’s Garden, Vallejo Project, Solano Resource Conservation District and Monarch Milkweed Project. Alana Mirror wrote three songs inspired by the installation, featured in her Pollinator Pathway Lawn Transformation Mini Series!

**Solano Resource Conservation District and Vallejo People’s Garden will be on-site promoting the Bay Area Butterfly Festival on June 1 with information on how to support pollinators! Solano RCD will have six-packs of Milkweed plants for sale for $10.

***Suzanne Briley from Vallejo People’s Garden will be giving talks on Creating Spaces for People and Wildlife, looking at ways to have garden spaces for ourselves while supporting wildlife. Talks and tours will be from 1-2 pm and 2:30-3:30 pm.

Vallejo Unity Garden (Vallejo Project)

Vallejo Project’s Unity Garden initiative restored an abandoned lot that was once filled with sand and garbage and turned it into a multi-level food forest with internationally influenced farming techniques, a mealworm farm and chickens. This garden is focused on urban agriculture.

Vallejo Project imagines a Vallejo strengthened by new generations of youth and young adults who are inspired to give back to their community as role models, advocates, entrepreneurs, and leaders, and who are able to articulate and implement solutions to challenges in the community based on their learned experience and knowledge gained through youth development programs.

***Free annual veggie and companion plants to take home while supplies last

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, the site has gone from food desert to food forest with the ability to eat from the garden year round. The homeowners 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. Magic Cabinet is supporting this year’s tour through its sponsorship.

The first seven food forest gardens were made possible through funding from the Benicia Sustainability Commission; the Solano County Water Agency supported the Sustainable Backyard Program throughout the county  from 2017 through 2024. Occasionally we combine funding from other programs to make larger projects possible.

EcoFarm Insight: Reflection, Observation & Irrigation

By Patrick Murphy, Program Manager

I had the opportunity to attend EcoFarm’s 45th Anniversary conference this year and had a wonderful time. My colleagues and I attended a variety of presentations and participated in a number of wonderful discussions with people from around California who work on similar projects related to urban agriculture, local food, and creating connections in their community.

There were a number of wonderful presentations that affirmed going back to basics like water retention, soil health, building up organic matter and biological activity, as well as taking your time to plan each project.

Again and again I heard from folks working in agriculture, education, farms and gardens that they had the most success when they took their time to reflect and observe before acting. Taking deliberate and well-paced steps to mulch, to build up organic matter in the soil, to increase water infiltration, and to develop rich and biologically active soil were the most impactful things they did. They stressed the importance of avoiding jumping into an idea that sounds good but is untested — the sheer force of nature is too powerful to work against.

Some key recommendations:

  • Take your time when you’re planning, and revisit a site multiple times before beginning work, with and without your plans.
  • Install a flow gauge and Schrader valves (similar to bicycle tire valves) in your irrigation system, and use a pressure gauge to check your system for leaks and issues.
  • Heat stress can make plants more prone to pest issues.

Here is a breakdown of some of the presentations:

Regenerative Landscaper Erik Ohlsen gave a talk about the importance of getting to know a site. He said that to truly understand a location, you should be visiting it in the rain, at night and early morning, and you should always check and recheck your plans with the reality of what is on the ground. Ohlsen also stressed the number of career opportunities which exist in landscape design.

Cameron McDonald from Santa Cruz Resource Conservation District spoke about the importance of monitoring water systems using flow gauges and pressure gauges. McDonald spoke about how farmers (and homeowners) can balance design, operations and maintenance, and irrigation scheduling to maximize yield, conserve resources, minimize nutrient loss, ensure uniform crops, and reduce fuel costs.

The mantra was “You can’t know what you don’t measure” — measuring flow rates is essential, and tools like flow meters for home gardeners, or telemetry systems, data loggers, and remote data collection for large-scale operations provide an enormous amount of information. SRCD has a number of common recommendations they offer to improve efficiency on farms, (1) use pressure regulators (these $13 units have saved Sustainable Solano hours of work), (2) fix leaks, (3) add spaghetti lines to direct the flow of water and (4) opt for oval-shaped hoses to reduce accidental kinks.

McDonald reiterated the standard recommended pressures are 0-30 PSI for drip irrigation and 100 PSI for sprinklers. Proper pressure management is critical for uniform water application; use a hand pressure gauge and Schrader valves to check your systems pressure, use one hand gauge to check the whole system to ensure consistent calibration. Elevation changes also impact pressure — every 2.3 feet elevation changes PSI by 1 PSI (increasing PSI when descending down, decreasing PSI when going uphill). Be mindful of the water hammer effect, a rapid change of pressure caused by quickly turning on/off valves, and look for unexplained pressure loss. Everyone should be flushing their irrigation system more often (once per year at least) and install or use soil moisture sensors for better field or lawn management. By implementing these strategies, farmers and homeowners can optimize irrigation systems for efficiency, cost savings, and irrigation uniformity.

Bill Snyder gave a presentation on a study he and his graduate students conducted on whitefly infestations attacking squash crops. In a 2016-2017 drought, potato whitefly infestation exploded. They had a theory regarding bidirectional stress on cotton plants, where the larva of the whiteflies were born and developed. Cotton plants under extreme heat stress are unable to fight off white fly infections, while populations of bugs and animals which traditionally consume these insects are also decimated by heat stress and overuse of broad spectrum pesticides. Snyder and his team found correlation between these extreme droughts and high volumes of insecticide use (per acre). In a natural experiment using center-irrigated fields and increased mulching practices, the Georgia team feels confident that the combinations of heat stress on plants and insects were a driving cause in the rise of whitefly populations. Learn more about his research here.

Sustainable Solano would like to thank the California Department of Food and Agriculture, Solano County Public Health and CHIP (the Child Health and Improvement Plan) for their support to attend the 45th EcoFarm Conference. Their support allowed us to learn so much about the state of urban agriculture, local food, and what other folks in our state, community and nation are working on. Thank you to the presenters and all the friends we made along the way.

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.
