To reach vets, kids, older adults, UC Master Gardeners partner with community organizations

Successfully supporting farming, homemaking and youth development with science-based solutions during UC Cooperative Extension's first 60 years in California prompted UC Agriculture and Natural Resources leaders to consider other ways the same concept could improve American lives.

One of those was the development of the UC Master Gardener Program in 1980, which recognized the need for science to inform sustainable and safe home food production for healthy diets, physical activity, education and mental well-being.

Over the years, the program has trained tens of thousands of UC Master Gardener volunteers to support residents of more than 52 California counties with environmentally sound ways to manage garden pests, reduce water use and grow fruits and vegetables. Today, there are more than 6,000 active UC Master Gardener volunteers.

Each of the 52 counties within the UC Master Gardener Program has unique projects that support its community needs, from reducing water use in home landscapes, diverting green waste from landfills and creating pollinator habitats to support pollinator populations. All counties answer gardening questions for free using a telephone hotline or email inquiry system. Master Gardener volunteers in many counties support community, school and demonstration gardens to share knowledge and spark inspiration. All focus their efforts on education.

To make still greater gains in outreach efforts, the UC Master Gardener Program enlists community partners that share its values. For example, the UC Master Gardener Program in Contra Costa County works with the County Department of Behavioral Health, Bi-Bett Corporation, Eden Housing and the Veteran's Affairs campus to provide gardening lessons to older adults, behavioral health patients and veterans.

“Gardens bring people together, regardless of race, color, age, sex, disability or religion,” said Missy Gable, statewide director of the UC Master Gardener Program. “Our volunteers in Contra Costa County carefully identified key gardening topics and the best delivery options for a variety of learning styles.”

The lessons covered vegetable gardening, soil health, composting, supporting pollinators and garden pest management.

UC Master Gardener volunteers in San Diego County worked with residential memory care communities and Alzheimer's San Diego to offer sensory gardening activities to people with dementia. The ‘Reminiscence Gardening' project in San Diego County was funded with a community grant and donations.

“Participants explored herbs, fruits and vegetables to activate the senses of sight, touch and smell,” Gable said. “In doing so, they worked their brains and their bodies, connecting their senses with memories, all the while also working on fine motor skills and muscle tone.”

Second-graders engage in activities during a field trip at a Santa Clara County park.

In Santa Clara County, UC Master Gardener volunteers developed science- and nutrition-based field trip activities to present at their demonstration garden and, with local grants, help pay to transport children from low-income neighborhoods to the garden for a day of hands-on learning.

Children learned about the plant life cycle and planted sunflower seeds to take home and watch grow. They tasted vegetables and discovered the benefits of eating fresh produce of many colors. After learning how to collect insects and identify them, UC Master Gardener volunteers invited them to release beneficial insects at the park.

“UC Master Gardener volunteers encouraged the children to return to the garden with their families to share their experiences,” Gable said. “Children are often an important driver of both food and recreation choices for families so encouraging them to continue their gardening journey is key to seeing change at the family level.”

During the COVID-19 crisis, when many families and children had to stay at home for their protection, interest in home gardening surged. UC Master Gardener volunteers and coordinators sought out safe ways to reach new gardeners with research-based information.

In Calaveras County, UC Master Gardener volunteers provided gardening kits for school children distance-learning at home. UC Master Gardeners in San Bernardino County offered monthly gardening sessions via Zoom to their community. UC Master Gardeners in Contra Costa and Alameda counties donated vegetable transplants to students and families in the Oakland Unified School District. In Santa Barbara County, volunteers taught local residents how to grow an abundance of high-demand fruits and vegetables for food banks.

“Our volunteers didn't skip a beat,” Gable said. “They live and work in the communities we serve, so they can identify where needs are and connect with like-minded partners to provide the widest possible distribution of trusted gardening information.”

Home gardening is more pleasant and successful with healthy soil

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.

Designate permanent walking paths so garden beds are not compacted by foot traffic.

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.”

Garden therapy during the coronavirus crisis

Director of the UC Master Gardener Program, Missy Gable, provided helpful advice for families who want to garden to relieve stress during the coronavirus crisis.
"I'm a huge believer in garden therapy right now," famed chef Alice Waters told reporter Aimee Rawlins. To find out how to dig in, Rawlins turned to the director of the UC Master Gardener Program Missy Gable.

"Start modestly and in a way that you can manage it,” Gable said. “If you've never done this before, don't transform a quarter acre.”

She recommends beginning by assessing space you have available for gardening - whether in the backyard, front yard or the corner of a balcony.

“Get to know the space, and watch to see how light moves around," Gabe said.

Most plants need about six hours of direct sunlight a day. Then figure out what kind of soil you're dealing with: Is it dry or rocky? Does it have the consistency of clay? Is there good drainage or does the water often pool? None of these results are “bad” or should dissuade you from planting there, but understanding what you're starting with will inform what you do next.

Gable recommends planting fruits and vegetables that you love to eat.

“For a starting gardener, depending on what your family is most interested in, I always recommend the standards: tomatoes, zucchinis, peppers, carrots, radishes, Swiss chard, eggplants. Those are fun and easy," she said.

If you have kids, Gable recommends including some plants that have a shorter yield time, so they can see the results faster. “Radishes are a really nice place to start,” she said. “They mature really quickly, and it's a fun way for kids to see the fruits of their labor quickly so then they're invested in the plants that take a little longer, like tomatoes.”

The UC Master Gardener Program trains volunteers to extend research-based gardening information to the public. Gable recommends looking up your local UC Master Gardener Program to get accurate information based on local conditions.

Turn food and garden waste into rich fertilizer with worms

UC Master Gardeners in Stanislaus County presented an all-natural, sustainable solution to disposing garden and food waste during a session for the community on worm composting, reported John Holland in the Modesto Bee.

All it takes is an 18-inch deep bin, equipped for drainage, and a supply of red worms. Provide the worms a substrate that contains a mix of high carbon materials - like shredded paper, dry leaves or sawdust - and kitchen scraps - such as fruit and vegetable cores and peels, leftover grains and coffee grounds. A few months later, the worms will have transformed the contents into a rich organic fertilizer ready to be applied to garden plants.

"It's a great fertilizer," said UC Master Gardener Dennis Lee. "It's very inexpensive for you to produce. You can do it indoors. There's very little odor - actually, no odor.

UC Master Gardeners partner with Alzheimer's San Diego in Reminiscence Gardening project

The UC Master Gardener Program of San Diego County has always been open to innovative ways of expanding its mission and passion for gardening into new parts of its community. The San Diego program has a rich history of successful partnering with other local organizations to reach under-served populations. An exciting new collaboration was unveiled in March 2018 when five UC Master Gardener volunteers took their newest public outreach project Reminiscence Gardening to the Alzheimer's San Diego's (AlzSD) social activities program.

Thirty participants, all community members being served by AlzSD, got their hands dirty and enjoyed a day of sensory stimulation through tabletop gardening activities planned by the UC Master Gardener leaders. The 90-minute program gave participants the opportunity to touch, move, smell, hear and see the joys of manipulating soil and plants to construct a simple potted creation to adorn their spring celebration table.

UC Master Gardener volunteers knew it would be important to develop activities that were fun and, hopefully, something those in attendance had previously enjoyed. With marigolds, chrysanthemums and mint varieties in hand, participants and caregivers, worked side-by-side and guided by UC Master Gardeners, dug into the bins filled with soil, pots and tools. Each set of participants was given three plants to pot up. As this first activity progressed, UC Master Gardeners could see that participants were being drawn out and interactions around the worktable were increasing. The physical, intellectual, emotional and social benefits of gardening were being experienced and shared by all.

Other sensory-heavy opportunities, all planned and guided by UC Master Gardeners, were included in the program.  Participants were asked to reach into a bin filled with loose soil and wriggler worms to re-familiarize themselves with that most basic part of backyard gardening – working the soil. A variety of plants in one-gallon containers were passed around. Each container was specially marked with an icon that invited the participants to experience the visual beauty, familiar smell, unique feel and, sometimes, sound and subtle taste of each plant. 

Of particular interest was an activity in which everyone was asked to explore a box filled with hand tools, seed packets and other items typically used in backyard gardening. Clearly, old memories were refreshed. A vintage hose nozzle drew the attention of one gentleman. He held it for a while then began making the motions used in hand-watering the yard, moving the nozzle back and forth while mimicking the sound of water rushing forth from the attachment onto a once green and promising flower bed. Tangible signs of success, such as these, were everywhere during the social activity.

Jessica Empeño, MSW, Alzheimer's San Diego's Vice President of Programs and Services was in attendance and praised the work of the UC Master Gardener volunteers. 

“Gardening was such a treat for our families. This activity stimulated all the senses – from the gorgeous colors of the flowers, the smell and taste of the herbs and the chatter and laughter that filled the room. Most importantly, those living with dementia and their care partners were able to socialize and have fun in a safe, judgment-free setting. We are so grateful to the UC Master Gardener Program for donating their time and supplies. We hope to have them back soon!”

The UC Master Gardener Program of San Diego was inspired by its growing understanding of the need for more everyday experiences to address the issues facing members of our community being affected by dementia-related diseases.  Those numbers are increasing at a staggering rate. The National Alzheimer's Association estimates that currently 5.7 million Americans have been diagnosed with Alzheimer's, with nearly two-thirds of those being women, and that number will almost triple by mid-century. In San Diego County, AlzSD offers social activities for individuals with dementia and their caregivers. The “Reminiscence Gardening” project's goal for those individuals is to boost energy levels, build confidence, prolong maintenance of existing skills and perpetuate a sense of purpose and joy through gardening.

Further collaborations between the UC Master Gardener Program of San Diego County and other memory care communities are in the works. UC Master Gardeners want to share their love of gardening and their advanced training from the university for the benefit of those in our community who need it the most. Many of us know first-hand the responsibility of caring for a family member with a dementia-related disease. We know, too, the joys and benefits of being outdoors and sharing time together with people we love.  We want to make a meaningful difference in our community and the Reminiscence Gardening project is a wonderful way to express that.
