Hannah Hartley’s face lights up as she gestures at the trees and soil around her and talks about regenerative farming, growing, and sharing the harvest and love of the Earth with her community.

“It’s a perfect design. From the soil community to the local community,” she said.

Hannah runs Bless’d Blossom, a regenerative market garden now in its third year on 1 acre she leases at Be Love Farm in Vacaville. The business brings together her love of farming, of growing healthy, nutrient dense, novel produce, and educating and serving others. It is a reflection of the connection she wants to have with the health of the soil and stewarding its care for the future while feeding people.

“For me, farming has always been a lifestyle — having the passion to cultivate garden veggies, and to pick them fresh at the utmost ripest moment for those around me and myself have been a cornerstone of my life,” she said. “It has naturally evolved into my career.”

Sustainable Solano is naming Bless’d Blossom as the recipient of our 2026 Doing Good business award. Hannah’s commitment to Earth Care and community makes her stand out. As does her beautiful heirloom produce and edible blooms.

Hannah specializes in greenhouse growing — pruning plants to grow vigorously, and trellising vertically to make the most of a small space and increase yield. In a 100-foot greenhouse, she can fit eight rows of tomatoes. That equates to more than 600 heirloom tomato plants towering more than 12 feet high. She envisions a future with market gardens built on the foundation of healthy soil in each city, which could revolutionize the food system.

Hannah has sold at farmers markets and farm stands. She also sells directly to many private chefs and local chefs who know the value of local food and seasonal menus, including Backdoor Bistro’s Chef Lindsey Chelini. This season, she has been selling most of her produce to the Food Bank of Contra Costa and Solano. The Food Bank has a grant that helps it pay her organic prices. She picks the food the same day it’s delivered and it stays in Solano County to go to people who need it. That grant has been a huge boon, but it ends in June, and she’s not expecting that it will be available again. Hannah is hoping to have a flower/vegetable Community Supported Agriculture (CSA) subscription soon. She can be found @blessdblossom on Instagram for updates.

Her market garden continues the regenerative farming revolution that Be Love Farm was founded on by original owners Matthew and Terces Engelhart. Regenerative farming places more physical demands on farmers, though once established can yield more through balanced, healthy systems. Hannah notes that weeding by hand is a constant “labor of love” in the regenerative garden. But there are parts that are simple that everyone could be doing as well. Hannah said cover crops are her favorite regenerative practice because they add life back to the soil and help it to flourish.

Hannah met her partner, Terry Ryan, when he was her most loyal customer at the Vacaville farmers market. Their paths aligned, and it turned out he was a regenerative shepherd, tending a flock of St. Croix heritage sheep, grazing them for fire prevention and soil health.

“He is an endless wellspring of inspiration,” Hannah said. “His honorable stewardship of the land and most tender nurturing of the creatures have deepened my understanding in devotion, and in regeneration and animal integration, to such a profound level I did not know was possible.”

At the end of Hannah’s garden season, her partner’s flock grazes on the cover crop, nourishing themselves as well as the garden — and the community of microbial and fungal life under the soil.

As she talks, Hannah returns to community, which has supported her career over the years. A love of gardening and growing started when she was a child in her mother’s backyard garden, lovingly built by her father. The setting allowed both plants and young Hannah to flourish. Her mother instilled a lasting love of nature, while her father encouraged her that any dream was possible if she put her heart and soul into it.

She said her older brother, Holden, instilled in her “the strength to persevere” mentally and physically. She didn’t realize just how much she would need that fortitude: on a midsummer day trellising up another tomato in the 110-degree greenhouse, or going another week of working nonstop during the busiest parts of the season.

And she has Jon, a friend whom she calls her “regenerative farm angel”, who volunteers to help her and offers encouraging enthusiasm on the hardest of work days and guidance on regenerative farming.

When she first approached Be Love Farm about leasing an acre, owners Rachelle and Loren Ditmore encouraged her to grow not out of necessity, but out of love. The Ditmores have since moved, but Hannah keeps that connection. She is building a regenerative flower farm in Yuba City, where she will grow flowers for Rachelle’s nonprofit, “City of Refuge,” a shelter providing housing and services for women and children.

She hopes these women can find peaceful restoration amongst the flowers, recognizing “there is still an abundance of beauty, grace and life to be lived. That there is still so much goodness all around us, to be savored and shared.” Hannah has found that divinity of goodness is most accessible in the natural world and most specially in the tender unfolding of the garden; this is her favorite part to share from the garden with her fellow community members.

She continues to have support from Be Love farm’s current owners, Rob and Zina Kirtlink, who have made her feel like a part of the family. Hannah also holds gratitude for her neighbors on Bucktown Lane, who took such tender care in her daunting early years of becoming a small business owner and farming regeneratively.

“They have always consistently shown up to my beginning farm stands and markets, poured so much life-affirming encouragement over me, and they purchased from me (even when I knew they were purchasing too many vegetables to be able to eat themselves!” she said. They check in on her to see what she needs. They are the epitome of what it means to “support your local farmer.”

Hannah grew up in Vacaville, but spent years traveling and overseas, with many of those spent with World Wide Opportunities on Organic Farms (WWOOF), a program where participants learn to farm sustainably and provide their labor in exchange for room and board. She felt called home in recent years, and now is putting down roots.

“The lifestyle of farming calls for you to be grounded,” she said. Planting a tree is a long-term commitment. “These plants demand your devotion.”

She has a degree in childhood education, and she can see a future where she’s pairing that love for learning and teaching with her passion for farming. She has future-focused approach and wants to instill that love, and the joy at watching that first sprout shoulder its way out of the earth, in the next generation of farmers. She feels it is her responsibility to not only share her knowledge and joys from the garden, but to also pass on the soil to the next farmer, in better condition than she found it. That is why she remains committed to regenerative farming.

“It’s so profound to ponder the garden,” she said. “The miracle of the garden and life itself.”

Learning All Things Compost at the Vaca Valley Garden Club

By Jill Hopkins, Vaca Valley Garden Club

We were excited to bring speaker (and composting expert extraordinaire!) Lori Caldwell to the Vaca Valley Garden Club for their September meeting. Here, club Vice President Jill Hopkins shares about Lori’s talk and the garden club.

Lori Caldwell presents all about compost

At the first regular meeting of the 2025-26 year for the Vaca Valley Garden Club, 54 members and guests were treated to the energy of Lori Caldwell, The “Compost Gal,” on Sept. 10. Lori’s presentation covered a series of compost contrasts for the Garden Club when she spoke of the appropriate Brown/Green Ratio; the difference between Damp and Mushy; the distinction between Aerating and Turning, and the distinct qualities of Hot vs. Cold piles.

Some important compost tips:

  1. Aerate that pile like you are “tossing a salad,” not stirring pancake batter!
  2. Chop your ingredients before adding them to your pile. Do not “dump and run.”
  3. Know your compost’s mood. Too much sun? Too much water? Bad bugs? Stinky? All fixable!
  4. Compost Happens! The time it takes depends on the ingredients, the care, and attention it gets, like most things in nature.

Sustainable Solano connected Lori Caldwell, consultant, landscaper, and educator, with the Vaca Valley Garden Club. In turn, Lori’s expertise in All Things Compost got people excited about a positive use of leaves, fruit peelings, straw, eggshells, tea leaves and branches. It was a good day for the Garden Club and a good day for Mother Earth!

Vaca Valley Garden Club

The Garden Club welcomes everyone with an interest in flowers, vegetables, trees, water, bees, bugs, birds, and the preservation of natural resources.

For additional information about the Vaca Valley Garden Club, attend one of its meetings at 10 am on the second Wednesday of the month (September-May) at Presbyterian Community Church, 425 Hemlock St., Vacaville. Before each meeting, an informal plant sale and boutique are held. Call President Glenda Riddle at (707) 330-8338 to learn more about the club.

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.

Grow Your Gardens and Knowledge Through Our Compost Classes

By Jazzmin Ballou, Program Manager

Compost happens all around us in real time. We see leaves, branches, and fallen fruit decompose back into the soil. In the winter the Earth’s energy is focused on breaking down that which is no longer alive or of use to plants, so that in the spring our soil can be nutrient-rich, and ready to use those nutrients to support the biggest production season of the year.

Soil health is a big focus for Sustainable Solano this year. This March through May, we’ll be offering classes for all levels of composting to build healthy soil. This series will consist of three classes, with a beginners composting class in March, an intermediate class in April and an advanced composting class in May. You are invited to attend the class of your choice or join us for all three to build your composting knowledge and connect with the different gardens where each class will be held.

Composting 101 – A Beginners Guide to Composting will be held at the Peace of Eden Community Garden at City Church in Fairfield. A brand-new three-bin system has just been built as an addition to this community garden, so this class is for folks who may want to compost but don’t know where to start. We’ll learn about composting basics: green waste vs. brown waste, what food scraps are compost-friendly and which aren’t, turning your pile, etc. Depending on time, we may weed or harvest from the garden so that participants can contribute to the compost bin. This class will be led by Lori Caldwell, who is not only a very experienced gardener and composter, but a very experienced teacher on those topics as well!

Composting 101 will be followed by Intermediate Compost Skills – An Introduction to Worm Composting, also taught by Lori Caldwell. This class will go over compost mishaps and how to troubleshoot bin repair, pests, etc. The time will also be used to introduce worm composting, discussing the benefits of worms, worm castings, and this compost method that is very friendly for those who want to compost but have less space to work with. The Vallejo Project Unity Garden will be hosting this class, with a worm bin and a three-bin compost system that has been paused due to pest issues and repair needs. This class will be interactive and potentially hands on, as we hope to show examples of bin repairs and give their compost system a bit of TLC.

Our final class of this series will be an Introduction to Advanced Composting Methods- Thermophilic Composting at the Vallejo People’s Garden on Mare Island. Michael Wedgley, owner of Soilogical, will teach this class, using his advanced understanding of soil biology to cover the thermophilic method of composting. As a more maintenance-intensive compost method, thermophilic composting creates an end product that is much higher in nutrients than traditional compost, as the goal is to heat up every inch of the organic matter being composted to a much higher temperature than we normally see for compost. This means it is turned much more intentionally and often, which is why after hosting this class, we will be offering opportunities for people to come back and support with the maintenance of this pile for the entire duration of time that it takes for it to break down (about six weeks).

We look forward to this ongoing process of learning about soil health and compost with you and encourage you to come ready to learn but also ready to teach! Every question asked, idea shared, comment made, in these open learning spaces feeds our own internal soils for when we are ready to harvest that knowledge and offer it back into the world, be that in our own backyard compost bins, or during a volunteer workday at a local community garden.
