By attending the tour, you will leave with practical knowledge that can transform not just your own garden but also the way you interact with the environment. Here are a few new projects and educational talks that will be highlighted during the garden tour:

An Introduction to Permaculture

Anne Freiwald will open the garden tour at Avant Garden in Benicia with a talk on permaculture. After the talk she will be available to answer any questions about the Permaculture Design Certificate Course beginning on Aug. 25.

Interns

Interns from our Benicia Youth Wellness Program will be at Avant and Swenson gardens providing opportunities to learn about local food and gardening. There will be a local food demo and taste test. Interns from the Vallejo Environmental Leadership Fellowship will be at Vallejo People’s Garden in the afternoon.

HOA

Visit this lawn conversion project designed by Michael Wedgley from Soilogical and installed by the Bay Vista Homeowners Association. This project not only serves as an example of environmental stewardship, but also as an inspiring model for HOA communities everywhere. This project will show resilient plants that are adapted to our local climate and require far less water than traditional lawns.

Solano Resource Conservation District

Pollinators require specific environments to thrive, and Solano RCD will be providing education at the Pollinator Pathway garden on how to create and maintain monarch habitats; they also will be promoting the Bay Area Butterfly Festival on June 1 and will have 6 pack of Milkweed plants for sale for $10.

Vallejo People’s Garden

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 1-2:30 pm and 2:30-4 pm.

We are still planning so there is more to come……

Together, we can grow more than just plants: We can cultivate a thriving environment for generations to come. Join us on this journey and be part of a movement that makes every garden a step towards connection and sustainability! Remember that every little change you make at home can contribute to a larger, more sustainable world. Whether it’s growing your own herbs on a windowsill or planting a pollinator garden in your backyard, the creative possibilities are endless!

While the tour is free to attend, we welcome donations to help keep this important work alive. This is our first food forest tour since the Solano County Water Agency discontinued funding for our Sustainable Backyard program, which supported the creation of many of these gardens. Your support ensures that we can continue installing new food forests, provide hands-on educational workshops, and empower more people to create sustainable, water-efficient landscapes in their own communities.

This also ensures that we will continue to have gardens to open for annual tours so they can continue to inspire others! It costs around $7,000 to create one food forest garden from design through installation. Our goal is to raise that amount in connection with the tour.

We invite you to mark your calendars for this transformative experience. The tour will take place on Saturday, April 26. Bring your family and friends, pack your passion for gardening, and get ready to be inspired.

EcoFarm Insight: Reflection, Observation & Irrigation

Feb 26, 2025

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

Apr 26, 2024

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.
