San Joaquin County gardeners boost business with UC Cooperative Extension Green Gardener qualification

For a healthier family and environment, San Joaquin County homeowners can select a UC-qualified Green Gardener to take care of their lawns and landscapes.

Green Gardeners are landscape professionals who are trained and tested on up-to-date, environmentally friendly, science-based landscape practices.

“We're improving the knowledge and skill sets of workers who manage an enormous amount of urban acreage,” said Karrie Reid, the UC Cooperative Extension horticulture advisor in San Joaquin County. “We're helping them understand that they have the power to effect change in water conservation, quality of storm water runoff, and the amount of pesticides that are in the environment.”

To become qualified as a Green Gardener, participants attend classes eight weeknight evenings and two Saturday mornings. The first module addresses the importance of healthy soil for healthy landscapes. UC Cooperative Extension scientists provide training on soil building, pest control and green waste management. The second module focuses on mastering efficient irrigation and conducting an irrigation audit. The final sessions focus on plants in the California landscape, including turfgrass, trees and shrubs.

Because the Green Gardener program is partially funded by a dumping fee paid by residents to the county landfill, green waste management is a key component of the program.

“We have to reduce our green waste,” Reid said. “Our urban soils are in need of organic matter. By building soil with green waste, we are solving two problems that inhibit our urban landscapes' sustainability.”

Beginning with Module 1, the Green Gardener qualification program is being held for the fifth time Jan. 16 to March 12, 2018. The registration deadline is Jan. 12.

On the first day of an earlier session, a landscaper wondered aloud if the $90 fee and, particularly, the time commitment, would be worth it. “Well, I know the answer is that it was worth it,” he said.

Qualified 'Green Gardeners' may use this logo in advertising.
In addition to all the knowledge gained, after passing the class, the participants can place the Green Gardener logo on their advertisements and be added to the online list of qualified UCCE Green Gardeners.

One Green Gardener, Jacob Wilson, wrote to Reid about a visit to a customer's property after a four-week break and found the lawn was significantly greener.

“I asked the customer if she had her sprinklers repaired,” Wilson said. “She said, ‘No, my sister adjusted the water schedule to two or three times during the night with shorter watering duration each time instead of watering once; like you said.'”

As his customer made her way back to the house, Wilson said he was feeling more like a professional.

Home gardeners aren't the only ones who can take advantage of the program. Reid has reached out to landscape professionals working in the county parks department and school districts. There are landscapers who tend apartment complex landscapes, commercial building landscapes, street medians and highway rights-of-way.

“I successfully pitched the program to the Sherriff's Department for their grounds landscape personnel,” Reid said.

No joke: The reality of the starving student and what UC is doing to help

As we celebrate the winter holiday season with its many joyful occasions, it's sobering to think how many people are in need of nutritious food. Millions of people are at risk of going hungry, says Feeding America. And according to groundbreaking studies by the University of California, we now know that a large number of college students are among the hungry.

A significant problem, “starving students” are not a lighthearted joke: students are going hungry and sometimes homeless, too. Food and housing insecurity among college students threatens their health, as well as their academic achievements.

Gauging college student food insecurity

The University of California began examining the issue of student food insecurity in 2015 with the Student Food Access and Security Surveys funded by President Napolitano as part of the UC Global Food Initiative. The resulting Student Food Access and Security Study was authored by the UC ANR Nutrition Policy Institute's Lorrene Ritchie and Suzanna Martinez and UC Santa Barbara's Katie Maynard.

The Student Food Access and Security Study examined the results of two surveys administered online in spring 2015 to a random sample of more than 66,000 students across all 10 UC campuses. Fourteen percent of the students -- 8,932 undergraduate and graduate students in all -- responded.

Nineteen percent of the students responding to the survey had “very low” food security, which the U.S. Department of Agriculture (USDA) defines as experiencing reduced food intake at times due to limited resources. An additional 23 percent of survey respondents had “low” food security, which the USDA defines as reduced quality, variety or desirability of diet, with little or no indication of reduced food intake.

Added together, an alarming 42 percent of the students surveyed were food insecure.

Communicating best practices and lessons learned

Soon after the Student Food Access and Security Survey results were published, partners of the UC Global Food Initiative throughout the UC system began developing the Student Food Access and Security toolkit.

The toolkit compiles best practices that have evolved at UC campuses as the university advanced efforts to nourish and support students.

Each section of the toolkit provides examples across multiple campuses to highlight the range of activities underway, as well as lessons learned.

Meeting basic needs: Food security and housing security

Expenses other than tuition can make up more than 60 percent of the cost of attending college today. The cost of living for college students has risen by more than 80 percent over the past four decades.

To better understand the prevalence of food insecurity among University of California students, the university has continued to examine the issue of student food insecurity and is beginning to assess students' housing insecurity. Food security and housing security are basic needs that students must meet to maintain their health and well-being so that they can focus on achieving academically.

Moving forward: implementing a basic needs master plan

A new report, “Global Food Initiative: Food and Housing Security at the University of California” was released December 20, 2017, and an executive summary is also available. This new report recognizes student basic needs as a statewide and national issue.

UC has done much over the past three years to help students meet basic needs. The findings from the new report will help UC go even further. The new findings will inform strategies for addressing basic needs security, including the creation of a UC basic needs master plan.

Perhaps we can retire the “joke” of the starving student after all.

How does the increased number of dead trees affect the timing and magnitude of wildfire? What would it take to get more Latino children engaged in science? Would volunteers be interested in teaching others how to preserve honey bee health? These are some of the questions that University of California scientists will try to answer through projects funded by UC Agriculture and Natural Resources.

Twelve new projects are being funded by UC ANR's 2017 Competitive Grants Program and High Risk, High Rewards Program to address high-priority issues in California.

With 45 competitive grant proposals requesting over $7 million and six high-risk high-reward proposals requesting over another $500,000, the number of requests received exceeded the funding available. 

“These projects truly demonstrate the forward-thinking nature of UC researchers,” said Glenda Humiston, UC vice president for agriculture and natural resources. “They're tackling problems and issues that strike at the heart of what matters to Californians. We're pleased to support and fund this critical work.”

The list of funded proposals is below and project summaries are posted on the 2017 funding opportunities web page at http://ucanr.edu/2017anrgrantsprojects.

Connecting with farmers over pineapple postharvest practices

At the end of a long year, sometimes it helps to reconnect with what motivates your work.

For Karin Albornoz — a Ph.D. student who works in the Diane Beckles Lab at UC Davis on molecular biology related to tomato postharvest chilling injury — that means getting out into the world to work directly with small-scale farmers.

"I spend so much time in the lab," she said. "Sometimes I spend a whole day in the lab extracting RNA or writing a paper. This reminds me why I am doing this work: to make a real-world impact."

Just over a week ago, she returned from a trip to Uganda where she did exactly that. In partnership with a local organization called Ndibwami Integrated Rescue Project (NIRP), Albornoz shared her expertise with farmers through several hands-on workshops about improving harvest practices and postharvest handling of pineapple, passion fruit and tomatoes. Her work was supported by the Horticulture Innovation Lab, an international agricultural research program led by UC Davis with funding from the U.S. Agency for International Development as part of Feed the Future, the U.S. government's global hunger and food security initiative.

Though Albornoz has worked with rural farmers before, this was her first time working in Africa. 

"Everywhere I looked, things were growing. There were people working in the field, women cooking, and everyone was working with food," she said. "I know there's a lot of stigma – when you talk about Africa, you see people's faces change and they're thinking about things like drought and famine and starving children. But what I saw doesn't fit that stereotype. The challenges they are facing seem to be about not having access to opportunities."

The workshops she led are part of the NIRP organization's efforts to connect farmers with more lucrative markets that pay higher prices for quality produce.


In this 2-minute video, Karin Albornoz visits a pineapple farm, leads a pineapple training and discusses next steps for this project led by NIRP in Uganda. The video clips and photos were taken by Karin while she was working and edited by Hallie Casey for the Horticulture Innovation Lab.


For months, Albornoz has been in contact with NIRP and making plans for the farmer workshops. She prepared postharvest handling manuals for each crop — pineapple, passion fruit and tomato — and asked questions to better understand local resources and the farmers' existing knowledge.

During her 2 weeks in Uganda, she visited farmers' fields and led three full-day workshops. The first workshop for about 50 farmers focused on pineapple — starting with understanding local quality parameters for this fruit, then best practices for harvesting, sanitation, storage and transportation. The second workshop was focused on tomato, with a similar structure, and the third workshop on passion fruit.

During the pineapple workshop, farmers had a chance to measure the fruit's total soluble solids through a refractometer.

Her favorite moment? The farmers' first chance to use a refractometer, to measure soluble solids and learn about sugar levels in the fruit. The refractometers were part of a small toolkit the organization will continue to use.

"They were excited to handle this device and see, in numbers, how the sugar levels of the fruit changed depending on the stage of maturity," she said. "Everyone in the room had a chance to try it."

Karin Albornoz leads a workshop in postharvest handling of pineapple in Uganda.

The experience reinforced her commitment to working with farmers and solving agricultural problems.

"A major mistake is to think that you are going just to train or teach other people because those people are always going to end up teaching you too," Albornoz said. "I made a promise to myself years ago, a personal commitment to working with people in vulnerable situations. I have to do this. Working in agriculture can be a very powerful tool to have an impact in the world."

As Karin's mentor and an Associate Professor in the UC Davis Department of Plant Sciences and Agricultural Experiment Station, Diane Beckles supported Karin's work outside of the lab and views such an experience as important to scholarly development.

"Something magical happens when we teach and engage in outreach," Beckles said. "We often deepen our understanding of what we are teaching, and interacting and engaging with others changes us in that process. It alters how we view and think about science in a way that is positive and rewarding, even though it is not easily quantified."

Almond and Walnut Pest Management Guidelines revised just in time for the holidays

‘Tis the season for baking lots of tasty treats. Breads, cookies, cakes, and candy are just a few that come to mind. What makes many of these treats so tasty is the addition of almonds or walnuts to the list of ingredients.

In California, we are lucky to be at the center of almond and walnut production. According to the California Department of Food and Agriculture's (CDFA's) latest Agricultural Statistics Review, more than 99 percent of the almonds and walnuts produced in the United States are grown in California.

Almond and walnut growers work tirelessly to supply enough nuts to not only satisfy domestic demand, but also for export. Worldwide, almonds rank as the largest specialty crop export. California is the top almond producer in the world, accounting for about 80 percent of all almonds grown. For walnuts, California ranks as the second largest producer in the world. To keep up with this demand, almond and walnut growers must be constantly aware of pests, diseases, and abiotic problems that can affect the tree and growing nuts.

The University of California Statewide Integrated Pest Management Program (UC IPM) has recently published revised Pest Management Guidelines for almonds and walnuts, helping growers prevent and manage pest problems with the most up-to-date information.

Revisions in the Almond Pest Management Guidelines include:

  • A new section on bacterial spot, a new disease of almond in California found in the Sacramento and northern San Joaquin valleys
  • A renamed section on fruit russeting, revised from the old powdery mildew section
  • Significant revisions made to the management section of navel orangeworm, one of the major pests attacking California almonds
  • Improvements on how to do dormant spur sampling section with easier-to-understand information on monitoring and thresholds

Revisions in the Walnut Pest Management Guidelines include:

  • Updated information on the association between walnut twig beetle and thousand cankers disease
  • New sections for Botryosphaeria and Phomopsis cankers, branch wilt, and paradox canker
  • Significant changes to the walnut husk fly management section

Both the almond and walnut revised Pest Management Guidelines also include updated information on fungicide efficacy, weed management, and vertebrate management.

Authored by University of California specialists and advisors, the Pest Management Guidelines are UC's official guidelines for monitoring and managing pests in California crops. For more information on pest management in these or other crops, visit the UC IPM website.
