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.

This week much of California is under a heat advisory or excessive heat warning, with high temperatures estimated to range from 90 to 108 degrees. Many home gardeners are wondering how they can help their plants, trees or shrubs survive the intense summer heat.
“We are getting a lot of inquiries around the state from people worried about how the extreme temperatures are going to affect the plants or trees in their yards,” said Missy Gable, director of the UC Master Gardener Program. “With a little extra planning, you can help your garden beat the heat and survive the hot summer weather.”
UC Master Gardener volunteers are available to help answer gardening questions and provide advice on gardening during the hot summer months. Here are four quick and easy ways to help make sure your plants and trees not only survive, but thrive.
- Don't fertilize plants or trees during hot summer months
Fertilizers aim to increase the growth of plants and trees. When a fertilizer is applied, especially one that is high in nitrogen, a plant is triggered to produce more green growth. An increase in growth means an increase in water and nutrient needs. During hot spells, it is especially hard to keep up with plant water and nutrient needs as soils dry out quickly and water may not be readily available. Save your plants (and yourself!) from stress by stopping fertilizer application before hot weather hits.
- Water trees deeply and less frequently
It sounds counter intuitive to water trees less frequently, but this is exactly what UC environmental horticulture experts recommend. “When watering trees you want to consider the roots below the tree and you want to encourage a network of deep roots. If you are only watering for short periods at a higher frequency, the roots will remain shallow since that is where the tree finds its water supply,” said Janet Hartin, UC ANR environmental horticulture advisor. “Deep roots mean a healthier tree that is less susceptible to disease.”
How much water a plant needs depends on the specific plant, how long it has been in the ground, and the type of soil where it is planted. In general, young plants or newly planted plants require more water than older more established plants. Clay soils absorb water slowly so watering can take longer but is typically done less frequently. This is in contrast to sandy soils that moisten and drain quickly. Typically, watering sandy soils take less time but has to be done more frequently. A Landscape Irrigation Scheduling Worksheet from the California Center for Urban Horticulture (CCUH) can be used to help calculate and determine an annual irrigation schedule for one irrigation zone.
- Mulch, mulch, and more mulch
When temperatures get extreme, having a good layer of mulch prevents soil from heating up excessively and loosing water to evaporation. Apply 4 inches of a medium shred bark mulch to insulate the soil. This protects the fine roots that plants use to feed from the surrounding soil. Mulch also helps maintain healthy soil ecology with earthworms and other de-composers that promote nutrients and oxygen in soil. Finally, mulch will pay for itself by maintaining a more consistent soil moisture so you can water less and have better success with your plants. Be sure to maintain the depth of your mulch to ensure you can benefit from all the services it provides.
- Wait to introduce new plants or trees until the fall
In gardening, timing is everything. New plants, whether grown in ground from seed or planted in your landscape from a container, have smaller root systems than more mature plants or plants that have been growing in your landscape for some time. Because root systems on new plants are smaller and need time to develop, these plants require more water more frequently. New plants introduced into a landscape during hot summer months have a significantly higher rate of failure. In California, it is best to introduce new plants in fall when the weather gets cooler. Winter rains can help keep new plants watered so they can establish and thrive in the future when temperatures are high and rainfall is scarce.
Always remember that you should take precautions for yourself while gardening in the summer months, especially during a heat wave. Remember to drink plenty of water and always have at least one quart of water per hour of outdoor activity. Limit time spent outdoors during peak temperatures and schedule any active time during cooler portions of the day. Always wear light loose clothing, a brimmed hat, and sunscreen as protection.
Thankfully we're not trying to garden on the surface of the sun. Unfortunately, sometimes it can feel like it for us and for our plants. Stay cool with these tips and consider planning for the fall to be an important part of your summer gardening activity.
“Fall, with its cooler temperatures, shorter days, and imminent rainfall, is the best time to plant a bee garden in California. Much of the plants' growth at this time will be in the roots rather than the vegetative growth, and that gives new plants an advantage when temperatures warm up and the soil dries in the spring. Fall and winter are usually the wet seasons in California, and a bee garden will benefit from the natural pattern of rainfall that helps plants get established,” according to California Bee-Friendly Garden Recipes (Pawelek et al. 2015)
With fall being the perfect time for planting consider making your home landscape bee-friendly and follow UC Agriculture and Natural Resources' California Bee-Friendly Garden Recipes - 12 rules of thumb for creating a bee-friendly home landscape:
- Learn the seasonality of plants and bees.
Bees need both pollen and nectar resources from plants all year long. Sugary nectar provides energy for adult bees, and protein-rich pollen is used to feed their young. Plant not only a variety of plants (to ensure both pollen and nectar resources) but also make sure that they bloom at different times throughout the year, with the most active times of bees in garden running from February to October.
- Provide a diversity of floral hosts.
A large variety of plants in a garden attracts a more diverse bee population. UC ANR researchers recommend planning a minimum of 20 different plant types to provide plenty of nectar and pollen sources for bees. If space or resources don't allow, consider plants that provide both nectar and pollen resources such as seaside daisy (Erigeron glaucus), blanketflower (Gaillardia x grandiflora), thyme (Thymus vulgaris), and coneflower (Echinacea purpurea).
- Give structure to the garden.
When planning your garden arrange plants so it is easy to observe the bees that are visiting your landscape. Place taller plants or shrubs in the back and smaller or shorter plants in the front. Or you can plant in the shape of an island to allow viewing from all sides.
- Plant in the sun.
Typically bees prefer flowers in the sunshine over the shade. Monitor the amount and location of sun in your home landscape and plant sun-loving bee-attractive plants in the sunniest section of your yard.
- Plant shrubs, perennials and annuals in patches.
Most bees will visit one type or a few types of flowers each time they forage, an abundance of the same flower variety allows for more efficient foraging for bees. The California Bee-Friendly Garden Recipes publication recommends a 3.5 ft x 3.5 ft flower patch of the same variety.
- Don't forget to seed annuals.
Plant seeds for spring blooming annuals and bulbs in the fall and take advantage of the winter rains and provide beautiful flowers in the spring. Great options include sunflowers (Helianthus annuus), Mexican sunflower (Tithonia diversifolia), California poppy (Eschscholzia californica), and zinnia (Zinnia elegans).
- Maintain flowers.
Prolong a plant's blooming season by dead-heading. As soon as flowers begin to fade, wither and brown, pinch or cut-off the flower stem below the flower or right above the first set of healthy leaves. This allows the plant to continue to invest in producing more blooms and not seeds.
- Create a watering regimen.
Regular watering of plants during blooming season allows plants to produce more flowers for a longer period of time. If a plant is water stressed it won't produce new flowers and nectar and pollen production declines. Consider plants that thrive in California's dry Mediterranean climate, UC Berkeley's Urban Bee Lab offers a list of the best bee plants with a large selection of California native options.
- Do not use pesticides!
Applying pesticides to your home landscape can kill beneficial insects and bugs visiting your garden, including bees. Consider using integrated pest management practices that are natural or organic methods like hand-picking, spraying with water or natural insecticides. Contact your local UCCE Master Gardener Program to learn more about integrated pest management.
- Consider plant climate zones.
Consider right plant, right place when selecting plants for your home landscape. Most gardening books, websites, plant labels and seed packets refer to a plants hardiness zone, climate zone or growing zone. Become familiar with the climate or microclimate in your area, the USDA Plant Hardiness Map and the Sunset Zone Map are a great starting guide for determining what plants will thrive in your garden space.
- Provide homes for nesting bees.
A bee-friendly garden provides cover and a safe place for bees to raise young. Most bee habitats are either in the ground or in pre-existing cavities. Provide a nesting home for bees in your garden by leaving a small section of your landscape unmulched for ground-nesting bees. Nesting blocks, drilled holes in untreated wood or “bee-condos” can be offered to bees that prefer a pre-existing cavity habitat.
- Provide nesting materials, including a water source.
Bees build their nests with mud, plant leaves and resins. Bees require a water source to not only drink but also to make mud for nest building. Fill a shallow water dish or birdbath to your garden, add small rocks or a floating cork for bees to rest and to prevent drowning.

Any loss of water is a concern as California's fourth summer of drought comes to a close. Missy Gable, director of the UC Master Gardener Program, suggests removing weeds so they won't compete with ornamental plants or edible vegetables.
If weeds are scattered throughout yard and mixed in with plants, hand-weeding is probably the best eradication method. Cultivation can damage ornamentals with shallow roots, bring weed seeds to the soil surface, and propagate perennial weeds, according to the UC Integrated Pest Management Pest Note on Weed Management in Landscapes.

Does a beautiful, low-maintenance, cost-saving landscape that actually improves the environment sound like a dream? If so, wake up, and welcome to the world of sustainable landscaping. Sustainable landscaping combines planning and maintenance practices for a low-waste, low-environmental impact garden space. Sustainable Landscaping in California: How to Conserve Resources and Beautify your Home Landscape, a new free publication by UC Agriculture and Natural Resources (ANR) demonstrates how creating a sustainable landscape is attainable.
- Choose the right plant
Selecting appropriate landscaping plants for your climate zone is the first step in practicing sustainable landscaping. If you live in the California desert growing tropical plants is probably not the most practical choice for your landscape needs. Visit the California Garden Web to learn more about your climate zone, and find resources for choosing the right plants for your garden.
- Water wisely
A typical California household uses one-third to one-half of its water intake in outdoor irrigation. How can a homeowner reduce water use? The answer is simple – water less. Overwatering an established landscape is more common than underwatering. Well-established plants should not be watered every day, reduce water use with a deeper, less frequent irrigation method.
- Prevent pests (safely)
Put down the pesticide! Integrated Pest Management (IPM) offers solutions for managing insects, diseases, weeds and other organisms. IPM techniques include eliminating pest habitats, encouraging natural enemies (for example, ladybugs for an aphid infestation), hand-weeding and applying mulch to your landscape. Only use pesticides after all other options have been explored and in the smallest quantities possible.
- Get to know (and love) your soil
Understanding what type of soil you have, its strengths and limitations is the first step toward a sustainable home landscape you can be proud of. Take steps to show your soil love and improve it with compost, mulch, and aeration as needed. To amend soil mix with compost evenly and deeply to avoid a layered effect that inhibits proper plant growth.
- Welcome wildlife
For a landscape to be truly sustainable it should provide a balanced ecosystem for a variety of plants and wildlife. Roll out the welcome mat in your landscape for birds, butterflies and other wildlife by providing access to food, water, and shelter.
- Conserve energy
Conserving energy in your landscape is easy. Retire power-tools and use hands tools like a shovel, rake or broom. Install light-emitting diodes (LED) lighting, which requires less energy to operate and lasts longer than traditional bulbs. Reduce energy use in your home by planting a shade tree which helps keep the home cooler during hot summer months.
The University of California Master Gardener Program extends to the public UC research-based information about home horticulture, sustainable landscaping and pest management. In exchange for the training and materials received from the University of California, Master Gardeners perform volunteer services in a myriad of venues.
