With winter soon upon us, it's a good time to treat your garden bed just like the one where you tuck in at night, says Dustin Blakey, UC Cooperative Extension advisor, director and UC Master Gardener coordinator in Inyo and Mono counties.
Blakey hosted a webinar on Facebook during Healthy Soils Week 2020 (Nov. 30 – Dec. 5) to advise home gardeners how to promote healthy soils to maximize their gardening success.
“Some genius suggested we call garden plots ‘beds,'” he said. “It makes sense. Mom was right. Don't stand or walk on the bed. Keep it neat and tidy. And cover it, in the case of a garden bed, with organic mulch.”
The goal is to end up with garden soil that holds adequate water, nutrients and air, supports soil life forms, like worms, insects and microorganisms, and is convenient to work with.
“If I have to get a mallet to bang a trowel into the ground, it's not healthy soil,” Blakey said.
As a first step, designate permanent walkways in the garden so only those areas become compacted by foot traffic, leaving the plots where vegetables will be grown undisturbed.
“Along parts of the Oregon Trail, almost 200 years later you can still see the ruts where the wagon wheels rolled, and plants aren't growing there,” Blakey said.
He recommended gardeners cover their walkways with gravel, decomposed granite or organic materials like wood chips, bark or grass. Installing raised garden beds is an ideal way to differentiate growing and walking areas. In his own garden, Blakey built the beds four feet wide to have easy access to all the plants while standing on the walkways.
Add compost to the soil inside the beds to reap a variety of benefits.
“It's often said, no matter the problem, compost is the solution,” Blakey said.
Compost provides a food source for beneficial microorganisms in the soil. If soil is sandy, compost helps it hold water and nutrients. If the soil is clay-like, compost loosens the soil, making it more friable.
Covering the garden soil surface with mulch or cover crops is also critical to soil health, Blakey said. The topping moderates the soil temperature, supporting the organisms living below ground. The covering helps prevent weeds, and as the mulch breaks down, it adds organic matter to the soil.
“You can also grow cover crops,” Blakey said. “I'm surprised how few gardeners use cover crops. Put some seeds in the ground instead of buying a bag of amendments.”
Cover crops can be part of a healthy garden crop rotation, keeping roots growing in the soil all year long.
“Grasses scavenge nutrients. Legumes fix nitrogen. I grow sweet potatoes. They shade everything and keep the weeds at bay. A daikon radish cover crop penetrates deep into the ground, naturally tilling the soil,” he said.
Blakey discourages a common habit of some long-time gardeners, frequent rototilling with a heavy machine, and rather encourages what he calls “gentle tilling.”
“You don't need power equipment. Experiment with using a shovel,” he said. “My soil is loose and easy to work. Some beds, I don't even turn. I just plant directly in the healthy soil.”

This is one of a series of stories featuring a sampling of UC ANR academics whose work exemplifies the public value UC ANR brings to California.
The coronavirus pandemic has disrupted life for everyone, with information about COVID-19 changing daily. For Californians who aren't fluent in English, obtaining reliable information is particularly difficult. Aparna Gazula, a University of California Cooperative Extension advisor who serves Santa Clara, San Benito and Santa Cruz counties, has been providing COVID-19-related information in Chinese and Spanish for immigrant Bay Area farmers.
In March, when restaurants shut down to curb the spread of the virus, many restaurants and wholesale produce markets cancelled produce orders placed with farmers. Language, cultural differences, low computer literacy and limited access to computers created barriers for small-scale, immigrant farmers in the Bay Area to quickly find new buyers for their perishable produce. Gazula introduced them to food banks, hoping they would accept the produce donations, but the food banks were not set up to pick up donations from small farmers.
Most small-scale farmers lack the financial capital to absorb the revenue shock. To help offset losses from unsold specialty crops, the UCCE advisor and Qi Zhou, the small farm program assistant specialist, have been helping Asian and Latino farmers complete English-language disaster aid applications.
“Since March, we have helped farmers apply for Covid-19-related farmer relief funds,” Gazula said. So far, she said, four of the 17 immigrant farmers who applied to the American Farmland Trust Farmer Relief Fund have received a total of $4,000, and 10 farmers of the 30 who applied to the California Family Farmer Emergency Fund received a total of $42,500.
Recently the U.S. Department of Agriculture expanded the list of specialty crops eligible for its Coronavirus Food Assistance Program to include bok choy, daikon and other vegetables with a deadline of Sept. 11. Communicating by phone and the app We Chat, Gazula and Zhou, who speaks Mandarin, notified local farmers, and advised them how to apply for the disaster funds. Zhou, USDA Natural Resources Conservation Service rangeland management specialist Ling He and another NRCS staff member assisted 64 farmers in completing applications over the past week.
Bob Kuang, president of the Bay Area Chinese Growers Association, shares UCCE information with the association's growers.
“Most of my members don't understand English so they [UC Cooperative Extension] help, like for policy and safety,” Kuang said, providing information the growers can't find elsewhere in Chinese.”
When she was a girl, Gazula saw how hard farmers work to make a living off the land while spending summers and winter breaks at her grandparents' farm in India, where they grew rice, mung beans and chili peppers.
“Farmers are very hardworking people, and small farmers even more so as they manage everything on the farm,” said the small farms and specialty crops advisor. “Their grit, determination to succeed and hardworking spirit truly inspire me.”
“I'd like to help them be successful as much as I can,” she said, “be it research-based information to farm successfully or bilingual support to help them better navigate regulations or apply for grant funds.”
In addition to helping farmers apply for financial relief, Gazula alerted the farmers to shelter in place rules and is delivering COVID-19 safety information about masks, sanitation and social distancing requirements in Chinese and Spanish to them.
“We also helped farmers implement COVID-19-related protocols on their farms,” she said. “We are currently putting together 200 COVID-19 kits that will help farmers comply with worker health and safety-related protocols on their farms. The COVID-19 kits contain reusable masks, hand sanitizer, bilingual Cal OSHA guidelines for employers regarding COVID-19, and a resources sheet listing where to buy the enclosed items.”
When she's not involved in COVID-19 crisis communications, Gazula continues to conduct research on nitrogen uptake in bok choy and bell peppers and irrigation management. She collaborates with Linda Chu, Guo Ping Yuan, Han Qiang Kuang and other Santa Clara County growers who allow the farm advisor to study crops on their farms.
“They do research, like test irrigation systems for right amount of water for the crop and nutrition – fertilizer – for the crop. They do lot of things,” said Bob Kuang, of the Bay Area Chinese Growers Association, who provides land at his farm in Gilroy for UCCE studies.
Gazula also advises farmers on how to implement the Food Safety Modernization Act (FSMA) on their farms and fulfill irrigated land nitrogen reporting. Fines for not complying with regulations can threaten the economic sustainability of small family farms.
Although the majority of growers she works with regularly have limited English and need assistance filing reports to the government, others consult her for production information they can't get elsewhere for the specialty crops they grow. Farmers of Korean, Japanese, Indian and Vietnamese ancestry and others attend meetings to learn the latest research on Asian vegetables such as daikon radish, napa cabbage, bok choy, on choy and various Asian leafy mustard crops including gai choy and pea shoots.
Gazula, who joined UC Cooperative Extension in 2016, currently works with about 180 small-scale growers in San Benito and Santa Clara counties and hopes to expand her outreach to farmers in Santa Cruz County.
To help small farmers adapt to climate change, Gazula and Zhou partnered with UC Agriculture and Natural Resources' Healthy Soils Program staff and Santa Clara County Farm Bureau for technical assistance and held workshops during the winter. Zhou helped the farmers apply for grants from the California Department of Food and Agriculture's State Water Efficiency & Enhancement Program and Healthy Soils Program. The 22 farmers who received CDFA grants brought a total of $424,111 into Santa Clara County.
The outreach work UC Cooperative Extension does wouldn't be possible without the help of bilingual staff such as Zhou, the scientist Gazula hired with grant funds in September, and some translation support from partner organizations and growers as well.
“Relying on partners for translation support isn't practical,” Gazula explained. “Outreach is most effective when it is targeted. It's not just literally translating words, but translating the information the words convey. Because we provide outreach materials to comply with regulations, the language in these materials is very technical and it's important that the information is presented accurately. We also depend on relationships with the farmers to extend the information within their communities. Long-term, it's easier to do outreach with support from our own staff.”
Competition is stiff for money to serve non-English-speaking Californians because the state is home to so many immigrants with different needs. The majority of the grants she uses for outreach are for food safety. The local Open Space Authority, which promotes preserving land for open spaces, has also provided funds for small and beginning farmer outreach and education.
Gazula draws on the expertise of fellow UC Cooperative Extension farm advisors across the state. For example, she said, Richard Smith, who specializes in vegetable production, and Michael Cahn, who specializes in irrigation and water resources, are always willing to help, even though they are not assigned to serve Santa Clara County.
“Farmers already have tremendous challenges when it comes to being successful,” Gazula said. “I feel language barriers and lack of access to the same resources as fluent English-speaking growers shouldn't be the reason they can't farm successfully.”
Across the United States, Americans are buying and growing plants as a pick-me-up during the COVID-19 crisis, reported Lisa Irizarry in Newsday. The paper focused its story on Long Island, N.Y., its area of local circulation, but turned to UC Cooperative Extension emeritus advisor Rose Hayden-Smith for commentary about the trend.
Hayden-Smith is the author of "Sowing the Seeds of Victory - American Gardening Programs of World War I" and now serves as the educational technology fellow for eXtension, an organization that helps extension professionals generate a more visible and measurable local impact. Hayden-Smith said plants can have a calming effect in stressful times. Increases in gardening occurred during the 1918-19 influenza pandemic and during World Wars I and II.
"We always turn to gardening during times of crisis in this country. The last big surge of gardening interest was during the last economic crisis," she said.
In the current environment, people are gardening for a family activity, to grow healthy food and acquire new skills, as reflected in the rise of other home arts, such as baking.
"It's earth-friendly and connects people with nature," Hayden-Smith said. "It's restorative and a way to be physically active. It feels as if it's something we take positive action on."
Central Valley residents from Visalia to Sacramento look forward every year to the beginning of strawberry season in early April, when roadside strawberry stands operated by Hmong and Mien farmers open to the public.
These farms grow strawberry varieties such as Chandler and Camarosa that haven't traded flavor for shelf life – they don't ship or store well, but they are far sweeter than varieties usually sold in stores, and they reach their peak ripeness and flavor in the fields next to the strawberry stands.
As strawberry season opens this year, farmers are hoping that customers will still stop by the stands to pick up their fresh, seasonal strawberries, and also that they will observe 6-foot social distancing and other guidelines to reduce the spread of COVID-19. UC Cooperative Extension agricultural assistant Michael Yang and I were interviewed on a local news station to encourage Fresno residents to practice these guidelines while supporting local farmers.
To assist Fresno strawberry farmers, the UCCE small farms team in Fresno County developed, printed, and distributed signs for roadside strawberry stands reminding customers to observe social distancing and other safety practices, as well as guidelines for farm stands to reduce the spread of COVID-19. Versions of the signs were also developed for strawberry stands in Merced and Sacramento, as well as a general sign for local produce at any farm stand.
Signs and safety guidelines were printed with funding from the Western Extension Risk Management Education Center, and Michael Yang distributed large printed versions of the signs to all strawberry stands on the Fresno County Fruit Trail map in Fresno County. These materials have also been shared with UCCE small farms and food systems advisors as well as nonprofit and agency partners and county Agricultural Commissioner's offices, and they are available for printing on the UCCE Fresno strawberry website.
Even as Californians shelter in place to contain the novel coronavirus that causes COVID-19, nutritious food remains vital to the health and well-being of our communities.
“Eating fruits and vegetables is known to benefit our overall health and help our immune system,” said Lorrene Ritchie, director of the UC Nutrition Policy Institute. “At a time when we need to be especially vigilant about staying healthy, eating healthy is essential.”
Farms, farm stands and farmers markets are listed as “essential businesses” in the state shelter-in-place order because they are important parts of the food supply. Urban farms are included in this category. As large produce distributors struggle to switch from selling large quantities to restaurants, schools and institutions to supplying supermarkets, these small businesses may offer a better selection of fresh foods, and may be closer to homes and less crowded.
To help minimize exposure and risk of spreading of the virus, urban farms need to follow some key guidelines from the CDC , said Jennifer Sowerwine, UC Cooperative Extension metropolitan agriculture and food systems specialist in the Department of Environment, Science, Policy and Management at UC Berkeley.
UC Cooperative Extension has compiled a list of resources for farmers, community gardeners and other people working in the food system to ensure that they can continue supplying fresh, healthy and affordable food to Californians.
“Social distancing, heightened health and hygiene practices and cleaning and disinfecting reduce the risk,” said Sowerwine.
Although eating a nutritious diet can boost our immunity, the Los Angeles Times reported produce sales plummeted by 90% or more at Southern California produce markets after the statewide shelter-in-place rules went into effect.
“It's worrisome to see that sales of fruits and vegetables are dropping so sharply, but not surprising,” said Rachel Surls, UC Cooperative Extension sustainable food systems advisor for Los Angeles County. “As people shop during the crisis, they may be prioritizing groceries that can be stored for a longer time in the fridge or pantry. And they may be on a very limited food budget, even more so than usual, so they are likely prioritizing essentials like bread and rice and baby formula.”
To support farmers in California, the UC Sustainable Agriculture Research and Education Program created a directory at http://www.calagtour.org for consumers to find local farms to purchase produce directly.
For families who have lost jobs and income, the risk of food insecurity increases. Some families could supplement their food from gardens and urban agriculture during this crisis.
Consumers must practice safety, too, when visiting farmers markets and farm stands. UC Cooperative Extension small farm advisor Ruth Dahlquist-Willard explained, "Things like keeping the minimum six-foot distance from customers, not touching any produce that you're not planning to buy, leaving as soon as you've made a purchase and washing the produce when you get home would be some good guidelines."
The virus is thought to be spread mainly from person to person, however there is evidence that COVID-19 can last for days on hard surfaces, thus the need to ramp up good health and hygiene practices, social distancing and cleaning and sanitizing of surfaces.
University of California research and extension faculty have compiled a list of helpful fact sheets and resources for farmers, community gardeners and other food system workers to ensure fresh, healthy and affordable food for communities across the state:
- Food-related resources for consumers and members of the food industry for COVID-19
- on the UC Davis Food Safety website.
- Sowerwine's PowerPoint presentation Safe Handling Practices for Fresh Produce in a Time of Coronavirus Disease 2019 (COVID-19) for urban farmers.
- A set of policies and procedures for safe food handling at the farm during COVID-19 provides step-by-step instructions for applying new food and health precautions on the farm including checklists, standard operating procedures and signage posting guidelines for preventing the spread of infection.
- COVID-19 safety guidelines for farm stands.
- Handouts for safe food-handling at home that can be distributed to customers receiving food from the farm.
All of these resources are posted on the UC Urban Agriculture website at https://ucanr.edu/sites/UrbanAg.
“During this challenging time, I am heartened by the quick and thoughtful responses by many extension, grassroots and institutional efforts, including Community Alliance with Family Farm's COVID-19 Responses and Resources for California Family Farms, Mutual Aid organizations where groups of young, healthy and lower-risk people are bringing food and services to vulnerable people who shouldn't be in public at all, and Bayareafood.info that seeks to support local restaurants, farmers, and food systems workers as they weather this latest storm,” said Sowerwine. “Crisis can spawn innovation, and I am hopeful that through this, we will come out the other end with a more compassionate and resilient food system.”
