UCCE scientists study feasibility of specialty crops for small urban growers
The vacant lots around your neighborhood could be growing fruits and vegetables and making local produce more accessible – while reducing energy needed to transport and distribute the food. Could turning those empty lots into small farms also become opportunities for economic development?
To answer this question, a team of researchers from University of California Cooperative Extension in San Diego County are investigating the economic feasibility of growing high-value specialty crops in urban settings like vacant lots. The project – led by Eric Middleton, UCCE integrated pest management advisor for San Diego, Orange and Los Angeles counties – is currently in progress at The Flower Fields in Carlsbad, a seasonal attraction for locals and tourists.
Tucked away in the back of the field is the Small-Scale Urban Ag Demonstration Site where Middleton and his team established a small farm on approximately 17,000 square feet, starting fall 2023. Funded by the U.S. Department of Agriculture National Institute of Food and Agriculture, the farm is designed to evaluate containerized production both outdoors and under high tunnels.
Growers don't necessarily need land, just space
High tunnels, also referred to as hoop houses, are semi-permanent structures that act similarly to greenhouses in providing a controlled environment. For the experiment, Middleton will compare cost, effort and durability of two types of high tunnels: one made of steel and the other out of PVC pipes.
“We want to give interested growers information on as many options as we can,” said Middleton, who explained that the project is motivated by the challenges of urban settings, including limited space and lack of arable land.
In the trial, they are growing turmeric, ginger and blueberries. The high-value crops were selected because of their potential to earn a profit. Data evaluating plant variety, soil mix, fertilizer, growth performance, yield and pest and disease pressures will be collected and reported when the project concludes in 2026.
As the crops develop in containers – blueberries in pots and turmeric and ginger in grow bags – Middleton pointed out the mobility aspect of the study, noting that growers don't necessarily need land, just space.
Whether it's a backyard or a rooftop, containerized production means easier transport, especially since vacant land doesn't always remain vacant forever and urban lots may often need soil remediation. Growing in containers solves the anticipated problem of having to relocate.
Where to set up shop in San Diego County
Jan Gonzales, project coordinator and community education supervisor for UCCE San Diego County, is leading the effort to identify available urban land in San Diego County as well as the policies and procedures for growers to access these spaces.
Gonzales is collaborating with community members who are working on similar projects to identify space for prospective growers.
“This has been done before for different objectives and for specific areas in the region, but the information was either project-specific and not publicly available, or not easy to find,” Gonzales said.
Having spoken with people associated with previous or ongoing agricultural land mapping projects, Gonzales has agreed to coordinate and facilitate an advisory work group to discuss areas of potential collaboration and develop project efficiencies. She anticipates holding the first group meeting before the end of the summer.
A production guide to help community members re-create the project
The ideal audience for a study like this is anyone who wants to grow specialty crops, according to Lindsey Pedroncelli, interim director of UC South Coast Research and Extension Center in Irvine, who worked on the project alongside Middleton when she was a staff research associate with UCCE San Diego.
“If you're a new grower or a grower who wants to diversify your crop production, what we're learning here can be applied to you,” said Pedroncelli.
Pedroncelli has been instrumental in bringing the experiment to life and documenting its step-by-step workflow thus far. The production guide, which is being created as the study unfolds, will include instructions detailing how to replicate the experiment from the ground up. Currently, it contains information on how to design your farm, the materials to buy, building structures, irrigation setup and crop management.
The most intriguing open question, whether the operation is profitable, is the driving force behind the production guide and will certainly be addressed, Pedroncelli said.
Book a tour and visit the farm
When visiting the farm, you'll encounter three varieties of blueberries: Star, Snowchaser and Misty. Snowchaser has been a top producer since it was planted in January, but the variety is known to be an early season producer.
Using only one variety of each, the turmeric and ginger were planted in late March-early April. With some unanticipated cold weather in San Diego County, both crops struggled when transitioning out of dormancy, leading to very slow progress, which the team is still navigating today.
Visually, Middleton and his team have noticed differences between the crops growing under the high tunnels versus those grown outdoors, although the data has not been analyzed to confirm or explain notable differences.
Attempting to demonstrate how to profitably grow high-value crops in urban settings using limited space and resources, Pedroncelli said she hopes this study will also encourage people to grow culturally significant crops for their communities.

Detection of fungus causing red leaf blotch spurs call for grower vigilance
Symptoms of red leaf blotch (RLB), a plant disease caused by the fungus Polystigma amygdalinum, have been observed for the first time in California across the Northern San Joaquin Valley.
Molecular DNA testing by the laboratory of Florent Trouillas, University of California Cooperative Extension fruit and nut crop pathology specialist, has detected P. amygdalinum. Pest identification was confirmed by the California Department of Food and Agriculture and U.S. Department of Agriculture.
The disease, named for the characteristic orange-to-dark red blotches that appear on infected leaves, is typically nonlethal for trees but has been a long-standing problem for almond-growing regions across the Mediterranean. Causing trees to lose their leaves prematurely, the fungal pathogen can significantly diminish crop yields in the current year and the next.
“It is one of the most severe diseases of almonds for Spain and the Middle East,” said Trouillas, an associate professor in the UC Davis Department of Plant Pathology. He recently co-authored an explanatory article on the UCCE San Joaquin Valley Trees and Vines blog.
With symptomatic trees seen in multiple orchards across Madera, Merced, San Joaquin and Stanislaus counties, Trouillas said RLB is already “somewhat widespread.”
“From the first observations so far, it seems like it affects some of the most-planted cultivars, like Nonpareil and Monterey,” he added. “We've observed it in a diversity of cultivars already.”
UC Cooperative Extension specialist urges taking preventive measures
According to Trouillas, RLB caused by P. amygdalinum is “highly specific” to almond trees, and generally only affects their leaves. Infection typically happens at petal fall, when small leaflets are first emerging and most susceptible to disease. After the pathogen's latent period of about 35 to 40 days, the first symptoms appear – small, pale-yellow spots on both sides of the leaves.
Those blotches become yellow-orange and then reddish-brown in the advanced stages of the disease during June and July. Now, with RLB symptoms becoming more prominent, Trouillas and UC Cooperative Extension advisors across the Central Valley have seen an uptick in calls.
“PCAs [pest control advisers] have been confused because they've never seen anything like this,” said Trouillas, noting that the yellow-orange-red blotches are symptoms unique to RLB and cannot be confused with other known almond diseases.
Applying fungicides after RLB symptoms appear is ineffective, Trouillas said. The best thing growers can do at this point is to report symptomatic trees to researchers so they can track the prevalence and distribution of the disease.
Growers who see signs of this new disease in their orchard should contact their local UC Cooperative Extension farm advisor.
Preventive measures are the best way to manage RLB, Trouillas said. He urges concerned growers to think ahead to next winter/spring and plan for fungicide applications at petal fall and – if rains persist – also at two weeks and five weeks after petal fall. Fortunately, those are the same three key timings for managing other diseases, like shot hole and almond anthracnose.
“Because RLB is something that is introduced and potentially aggressive, it will be important for growers to keep that in mind next year and be on schedule for next year's spraying program,” Trouillas said.

/h3>/h3>A recently published study reveals that California students appreciate Universal School Meals, reporting that having meals free of charge for all students made school meals more accessible, reduced stigma, improved food security, and streamlined the process for receiving meals. Prompted by the rise in food insecurity during the COVID-19 pandemic, in 2020-2022 the USDA implemented an unprecedented change allowing schools to serve meals free of charge to all students regardless of household income. For many students, school meals are their primary source of nutritious food. This qualitative study, conducted in 9 different regions in California, interviewed 67 middle and high school students, representative of the demographic profile of students in the state, about their experiences with Universal School Meals during the pandemic. Students expressed widespread appreciation for the program and a desire for its continuation. Students of different backgrounds agreed that the program supported food security by relieving the financial burden on families during an economically hard time. This was achieved through easier access to school meals by eliminating income barriers and the eligibility process. Universal School Meals also reduced the stigma faced by those who receive free or reduced-price school meals by including everyone in the program. There is still room for improvement, as students expressed concern about the quality and quantity of food served during the pandemic and perceived greater food waste. California was the first state to commit to continuing Universal School Meals beyond the 2021-2022 school year. This study was published online in the Journal of Nutrition Education and Behavior co-authored by Dania Orta-Aleman, Monica Zuercher, Kassandra Bacon, Carolyn Chelius, Christina Hecht, Ken Hecht, Lorrene Ritchie, and Wendi Gosliner of the Nutrition Policy Institute and Juliana Cohen of Merrimack College. This research was funded by California General Fund SB 170.
In response to the COVID-19 pandemic, US Congress authorized the USDA to provide free school meals to all students regardless of family income. After the 2021-2022 school year, most states reverted to previous eligibility criteria, but California and Maine implemented permanent universal school meal policies. A new study published in the Journal of the Academy of Nutrition and Dietetics analyzed parent perceptions of these policies during the 2021-2022 school year using surveys and interviews. Results showed that parents, whether eligible for free or reduced-priced meals or not, believe universal free school meals help save time, money, and reduce stress. Parents showed high support for these policies and felt they reduced stigma, especially when applying for free or reduced-price meals. Opinions on meal healthfulness and quality were mixed, but parents appreciated the impact of the meals. Researchers suggested that states should consider adopting universal free school meal policies to reduce stigma and encourage higher participation among low-resource families. The study was conducted by Nutrition Policy Institute researchers Wendi Gosliner, Kenneth Hecht, Christina Hecht, Monica Zuercher, and Lorrene Ritchie, Leah Champman and Deborah Olarte from Merrimack College, Marlene Schwartz from the Rudd Center for Food Policy and Health, University of Connecticut, Lindsey Turner from Boise State University, Michele Polacsek from the University of New England, Anisha Patel from Stanford University and Juliana Cohen and Tara Daly from Merrimack College.
