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 talk on healthy soil from “CompostGal” Lori Caldwell. Itinerary pick up will be from 9-11 am.

** Refreshments and free seeds will be available

Apricot Alcove

 This front yard food forest primarily focuses on native plants and pollinators. It was established as part of Sustainable Solano’s Fall 2025 Permaculture Design Certificate (PDC) course. The front lawn was transitioned to a large bioswale, fed by a laundry-to-landscape greywater system. Drip irrigation runs to an apricot tree encircled by natives, and the hope is for the apricot tree to provide shade and privacy once fully grown.

 

Giardino su una Colina (Garden on a Hill)

 

A 6-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 June 14!

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.

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 supported the 2025 PDC. Pick up a DIY garden design template with a plant list. The garden will also feature live music!

California Native Plant Society (CNPS) Gardens

Bird Haven Retreat – CNPS

Visit this native plant garden and see what 30+ years of gardening dedication to native plants can create. Welcoming shade plants and green grasses abound under thriving and tall buckeye and big leaf maple trees that gain water from harvested roof rain flowing to a dry creek bed. A mature manzanita row lines the side yard walkway. Feel the intimate wildlife habitat backyard space as you find small birds flying between the branches of tall native shrubs such as the fragrant mock orange, red-blooming spice bush and the heart-shaped leaves of the western redbud. Sun-loving native perennials border a native grass lawn, and alum root hugs the shade of the understory. The owners are grateful for the relaxed and comfortable habitat that native plants provide for them.

Habitat & Harvest Garden – CNPS

(Formerly Barley’s Backyard Food Forest — one of Sustainable Solano’s first installations in Benicia — the garden is now with a new family that is adding native habitat)

The view of this welcoming tiered front garden begins right at street level with sidewalk appeal of a chaparral-inspired garden including evergreen manzanita, easy-to-grow buckwheat, and native grasses. Step down to the next tier to find a cozy deck space to sit within the garden and share the space with emerging caterpillars, hummingbirds and native pollinators as the seasons unfold. Tiered terraces and integrated drainage allow for meadow and sage, milkweed, and strawberry groundcover plantings to absorb stormwater while supporting plant health. View coffeeberry, monkeyflower, penstemon, and salvia which attract and support additional wildlife in this habitat-rich garden. Mature fruit trees, perennial edibles and vegetable beds combine with the abundance of native plantings for a harmonious full habitat that supports biodiversity and spills into the back yard as well. This garden family truly feels a calm connection with nature when they are in their garden space.

Tended Wild Garden – CNPS

Come and visit this wild-like garden to gaze upon the beautiful annual flowering natives such as the yellow and white tidy tips and the purples of lupine in the front garden patch. Travel through the side yard of orange California poppies, stepping rounds and a dry creek bed that collects rainwater, to the large backyard garden that flourishes with a thriving tapestry of wildlife-supporting native plants. Verdant grasses and spring ephemerals surround a bird bath that California Towhees are happy to visit. Tall shrubs such as rosa californica or the keystone tree coast live oak have become safe places for nests of breeding small birds. Flowering colorful annuals are servicing the many pollinators such as hover flies and bumblebees that visit the flowers for pollen. This habitat refuge is where the family connects with the wonders of nature. The owner collects seeds of many native plant species to continue the annual flowering habitat year after year.

Vallejo Food Forest, Pollinator & Community Gardens

Enchanted Cottage Garden

 This front yard lawn was replaced in May 2017 with two swales, above-ground rainwater collection and a variety of fruit trees, grapes, herbs, and year-round pollinator plants mixed with annual vegetables. There is a path through it with seating for anyone who walks by. The food forest concept extends to the back garden. This yard has inspired several neighbors to transform their landscapes. Produce from the garden is used in the food forest keeper’s small home-based restaurant and they donate excess produce.

Loam Sweet Loam

This 700-square-foot front yard food forest was sheet mulched over 3 years ago and it includes a swale. It includes multiple layers of permaculture plants: young fruit trees, drought-tolerant shrubs such as rosemary and lavender, and soil-amending groundcovers.

The homeowners extended permaculture principles into their 900-square-foot backyard vegetable garden, and hosted workshops with Sustainable Solano and Greywater Action for the addition of a laundry-to-landscape greywater system to irrigate young fruit trees. Future plans may include diverting rainwater from downspouts into existing rain barrels to irrigate the yard, expanding the area irrigated by greywater to incorporate more trees, and increasing plant diversity throughout the yard to support a strong and edible ecosystem.

Vallejo Unity Garden (Vallejo Project)

A Youth-Led Food Forest & Community Hub

 The Vallejo Unity Garden is a youth-led initiative of the Vallejo Project, rooted in a vision of food justice, sustainability, and community healing. For the past five years, young leaders have worked alongside community partners to transform this space into a thriving food forest and sustainable garden designed to nourish both people and place.

Blending natural, ancestral, and modern agricultural practices, the garden integrates local, Indigenous, and international growing techniques to maximize food production in an environmentally responsible way. From soil regeneration and composting to water conservation and permaculture design, the Unity Garden serves as a living classroom where youth and community members learn sustainable food systems that can be replicated at home and across neighborhoods.

This work is especially grounded in service to our immediate community, providing fresh, healthy food and hands-on learning opportunities for our unhoused neighbors and residents surrounding the Vallejo Project site. The garden is not only a source of nourishment, but also a space of dignity, connection, and empowerment.

In addition to the food forest, the site includes a small-scale farm with animals and a community workshop space where participants build DIY projects and develop practical skills. Every Saturday and Sunday 10  am-4 pm, the space comes alive with volunteers, youth leaders, and community members working together to grow food, share knowledge, and build sustainable solutions.

This ongoing effort has been made possible through the dedicated partnership and support of Sustainable Solano, the Global Center for Success, the City of Vallejo, and Justice Outside. Together, we are cultivating not just a garden, but a model for community resilience, youth leadership, and collective care.

Inspired Garden (Wildway Garden)

Homeowners Carolyn and Mike attended the 2025 Garden Tour and dug swales for the garden installation at Touro University. They to apply permaculture principles to their yard.

Carolyn is a pruner and horticulturist working towards a degree in Arboriculture at Merritt College. Mike teaches paragliding locally with Penguin Paragliding. They moved into our house in 2022 and were excited to have our first chance to garden in our own space after having worked on various farms in the past.

They could see the potential in the big back yard, which had been neglected for years and was covered in tall fennel but still had a number of mature fruit trees. They immediately planted a peach tree, a nectarine tree, and an asparagus patch and watched with excitement as the mature trees bloomed: apricots, plums, apples, loquats, and two prolific quince bushes. Over the years they have distributed multiple massive truckloads of arborist wood chips from ChipDrop into the garden to build the soil, in addition to planting cover crops and spreading compost. The sunniest part of the yard now hosts the vegetable garden and some perennial edible plants such as tree collards, walking onions, rhubarb, and raspberries. They installed a drip irrigation system and four valves/zones, mostly for the fruit trees and veggies. California native plants fill the front yard and many other spaces in the back yard, where they attract pollinators and provide habitat to lots of critters.

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.).

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.

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.

Why Hampton Bay HOA Decided on Sustainable Landscaping

By Rick Theisen, Hampton Bay HOA Board Member / Treasurer

We’ve worked closely with Rick and the Hampton Bay landscape committee in a partnership to demonstrate how a waterwise, beautiful native garden could replace water-hungry lawns in HOA common areas. Here, Rick offers some insight on that partnership and the first pilot project.

Prior to the 2016-2017 rainy season, the wettest on record, most of the state was experiencing increasingly worsening drought conditions. At one point, people were doing the odd and even dance to conserve water. Remember that? But, after the 2016-17 rainfall, most thought that we were out of the woods. Virtually the entire state was transformed. No more drought, said some! Reservoirs were refilled to capacity. A harbinger of good things to come!?

A couple of us that had been on the board of the Hampton Bay association, at that time for more than 15 years and intimately familiar with the finances, weren’t so sure about the optimistic prospects. There were other factors in play for our community that were compelling us to think otherwise. Common area landscaping was relatively vast with large swaths of grass that required a great deal of water. The plants and shrubs were aging and outdated — most installed at the community’s inception 40 years ago. Most of the irrigation was the original equipment — inefficient and high maintenance spray heads in the plant and shrub perimeter areas, as well. And, to exacerbate matters, the city was steadily increasing the water and sewer rates. So, we were having to increase association dues more than desired due to the rising costs of water and related landscape maintenance.

We knew we couldn’t sustain the path we were on and were also a bit cynical of the drought prospects, suspecting that the overabundance of rain in the 2016-17 season was a teaser by mother nature. In retrospect it was, of course, a fluke year in a worsening 20-year, some say 100-year, drought.

So, we began a campaign advocating to the other homeowners (100 units) for a complete transformation of the common area landscape and irrigation in an effort to mitigate increasing water usage costs and thereby curtailing future dues hikes. It was a challenge at first because the word “drought” was no longer front and center in the media. However, over the next one to two years as talks of the drought resurfaced, the reality we were trying to convey — steadily increasing water/sewer rates, increasing landscape and irrigation maintenance costs and, of course, dues increases — started to bear fruit.  Slowly homeowners began to jump on board.

We developed a three-phase implementation strategy over a two- to three-year period that would allow us to stagger the costs. One of the members of the landscape committee, which we had formed specifically for this broader transformation project, had prior experience with a nonprofit whose mission was to assist the residents and merchants of Solano County to conserve water by adopting sustainable landscaping methods. Prior to the beginning of Phase III (the conversion of the larger areas of grass) we met with Sustainable Solano (SuSol) and immediately realized the benefits of sustainable landscaping. We were hooked.

Hampton Bay HOA Project Slideshow

Hampton Bay HOA Project

We designated a large grassy area as a pilot so that we may learn to adapt the sustainable methods to our unique environment. Michael Wedgley, the SuSol designer and soil enrichment consultant, proposed a design consisting of a variety of true California native plants, water catchment basins (swales), a basic pipe system to divert the nearby roof’s runoff to the swales and wood mulch to help retain moisture. The long-time and trusted gardener for our association implemented the design including a very efficient drip system to help the plants take root, of course.

Keep in mind that we were doing this during the pandemic and experienced several delays due to lockdowns, supply shortages, crew shortages and illness. It took longer than expected, but the end result began to garner approval from homeowners. We observed that the native plants were taking root almost immediately and within a few short weeks had noticeably grown.

In this large pilot area, with the new drip system combined with the moisture-containing properties of mulch, we calculated a water savings between 70 to 90%. Because we installed true California native plants, the theory is that within one to two years we’ll be able to turn off the drip irrigation and save 100%. It will definitely pay for itself over the long term. We’re looking forward to converting the remaining large grassy areas in our community.

Feb. 28, 2022: Preparing for Installation

We will provide periodic updates on the process of creating two sustainable pilot sites at Hampton Bay HOA.

After finalizing the designs for the two pilot sites with the HOA, Permaculture Designer Michael Wedgley and landscaper Jerry Saitta met at the site to talk over the designs. Both sites will replace the grass with sustainable, low-maintenance, waterwise landscaping that captures rainwater and incorporates native plants.

At the larger site, Michael marked the location of the swales — in-ground trenches that will capture rainwater and roofwater from the nearby building so that the water can sink into the ground, build healthy soil and provide on-site water for the plants. The smaller pilot site will also have a swale that captures roofwater.

Jerry and Michael discussed digging the swales, plant spacing and other aspects of the project. The next step will be to begin the installation.

Large pilot site
Small pilot site

Dec. 4, 2021: Town Hall (with video)

We will provide periodic updates on the process of creating two sustainable pilot sites at Hampton Bay HOA.

The town hall with HOA members on Dec. 4 was a great opportunity for Permaculture Designer Michael Wedgley to share the proposed designs for the two pilot sites that will replace the grass with sustainable, low-maintenance, waterwise landscaping that captures rainwater and incorporates beautiful native plants and shrubs.

Hampton Bay HOA has been incorporating sustainable practices at the property, including ending the use of chemical herbicides like glyphosate several years ago and using wood chip mulch on the hillsides.

Michael highlighted how the designs for the larger site and the smaller mailbox site will look to nature as a guide, as opposed to common approaches to landscaping that have relied on indiscriminate water usage, chemical fertilizers and pesticides, and “mow and blow” maintenance. Read his talking points from the presentation here and watch the video below.

Here are some highlights:

Plants

  • The plants are planned and positioned so that they can grow to their full size without the need for constant trimming.
  • Plants in the designs serve multiple functions in the environment, including plants that pull nitrogen from the air and deposit it into the soil where it becomes more accessible to other plants.
  • Native plants are best acclimated to our wet winters and dry summers and have co-evolved in harmony with local pollinators to flower and fruit at the right times.
  • The selection of plants focused on multiple senses (how they look, their fragrance) and a small number of herbs that could be harvested and enjoyed. Multiple layers and heights of the plants make it aesthetically attractive.

Rainwater catchment

  • Capturing rainwater from the roof in basins at the larger site will give that rainwater time to sink into the soil. Multiple basins will create somewhere for the water to overflow into during larger rain storms.
  • In-ground swales (basins) will be filled with wood chips at both sites, which will act like a sponge to hold onto the rainwater until it can sink into the ground.
  • At the smaller site, a diverter will be installed that can send rainwater away from the in-ground swale during larger rain events
  • Because the sites have mostly native, low-water usage plants, they likely won’t need supplemental irrigation after a year or two

Soil

  • Michael talked about the microbes he looks for in healthy soil that help to cycle nutrients that plants need to thrive. Without this soil biology, including bacteria, nematodes, protozoa and fungi, soil cannot release those nutrients effectively to plants.
  • After Saitta’s Gardening & Landscape installs the final designs at the pilot sites, Michael will apply compost extracts to help build soil biology, which in turn will start to create the structure within the soil that will allow it to hold more water and better support plants.
  • Wood chips on top of the soil will protect it from compaction from rain and break down over time to improve the soil.

The hope is that these concepts from the two pilot sites will provide ideas that can be incorporated in later phases that will replace large lawn areas in the HOA. This will make Hampton Bay HOA a model for how other HOAs could do landscaping and conserve water.

Meet Designer Michael Wedgley

Michael Wedgley is creating the designs for both of the pilot sites at Hampton Bay HOA, and will be working with the HOA’s landscaping company to coordinate the installation of the designs. Michael will also build the soil biology of the sites to create healthier, more lush environments in which the plants can thrive.

Michael is a Bay Area native and a Permaculture Designer who specializes in edible and native landscapes, as well as applied microbiology for the elimination of pesticides and fertilizers. He is a certified Soil Foodweb Lab Technician assessing the microbiome of soils to help growers and gardeners understand the biological needs of their soil, and operates under the business name Soilogical BioSolutions and Designs.

He also is the founder of the nonprofit organization Transformative Soil and Landscapes, which operates primarily in Contra Costa County and organizes the community around installing regenerative food forests in people’s yards and in community gardens. His love for nature and food are often brought together in residential homes to help people design their landscapes into foodscapes that provide the best quality food available while integrating rainwater catchment, aesthetics, nature, and biology.

The photos in the slideshow below reflect how Michael’s design work and focus on healthy soil can create a thriving ecosystem in a garden design that attracts and celebrates pollinators. (Photos of this garden in Martinez provided courtesy of Gina Casey of GMC Photography and Video)
