It's only right that our University of California Cooperative Extension (UCCE) San Bernardino County Master Gardener ‘Trees for Tomorrow' team of volunteers are our featured ‘Spotlight' Master Gardeners for September, 2021. They provided vital education to Redlands residents receiving gratis trees through a multi-partnership grant obtained by Inland Empire Resource Conservation District Manager Mandy Parkes.
It's an honor and privilege to recognize UCCE San Bernardino County Master Gardener Project Leader Debbie LeDoux and her dedicated team of 'Trees for Tomorrow' volunteers: Zhibo (Sandy) Anderson; Consuelo (Connie) Davis (pictured); Pam O'Connell; Gail Sefl; and Husam Yousef. These dedicated Master Gardeners were tasked with helping residents select, plant and care for drought, heat, and pest tolerant trees. (Species including Chilopsis linearis 'Bubba', and Pistacia x 'Red Push' were selected due to their excellent performance in our University of California/United States Forest Service research project as 'climate-ready' trees able to withstand harsh conditions related to our changing climate.) Working with a team of California Climate Action Corps volunteers, civic leaders, Common Vision Coalition, and other groups, nearly 100 trees were planted in yards and parks lacking the preferred 25% tree canopy cover.
Trees can cool urban heat islands by 50 degrees Fahrenheit or more during spring and summer, creating welcome oases in hot inland communities. With spring 2021 temperatures so high they broke previous records on multiple dates, the project is especially timely and necessary.
In addition to proper tree selection, trees require the right long-term care. Master Gardeners will continue to provide advice on irrigation, pruning, fertilizing and pest control to residents receiving trees long after the trees are planted. This is critical since an average urban tree lives less than 20% of its potential lifespan due largely to poor care. The long-term engagement of Master Gardeners with residents is as important as is selecting the right species.
UCCE Master Gardeners are all volunteers, giving of their time and talents to enhance the quality of life for individuals and families who call San Bernardino County their home. Each Master Gardener is required to complete a rigorous 18-week training class complete with exams, class projects, and lots of participation! Due to COVID-19, volunteers had to master key horticultural concepts during the first ever all on-line training class. Only recently have they been able to meet fellow Master Gardener graduates and, in some cases, the Redlands residents they mentored through the tree canopy enhancement project. They truly exemplify community spirit and all it takes to successfully work together under adverse conditions. Kudos to each and every one of you from Master Gardener Coordinator Maggie O'Neil and myself! You are creating a cooler, greener and healthier environment for our children's children.
I asked the honored Master Gardeners their thoughts on the project. Here's what they had to say:
“The Redlands tree canopy project was the best volunteer project ever. In the midst of Covid-19, horrific politics and way too many good byes, it was a truly joyous experience. The legacy of being a part of the group that promoted healthy sustainable trees, knowledge of how to plant and care for them, tips on maintaining their health and beauty was the absolute best. For me as a Master Gardener, it was so much fun. I loved the site walks and getting to help our participants select the perfect sustainable trees for their properties. What started as a one-on-one visit often expanded to an enlarged group of neighbors and extended family. I got to give out many handouts and publications and promote our excellent Master Gardener program. I got to share our helpline email and phone numbers. I love the fact that I have been asked to revisit sites to see how great they are doing (once to make sure the tree did not look funny!). I receive emails every now and then asking me questions and showing me pictures of "Our Trees.” So much fun, Janet. Thank you. By far the coolest project ever! Pam O'Connell

There are a few things that really made an impact on me.1) It was rewarding to attend the Zoom presentation you developed that provided education to various professionals on the importance of planting sustainable trees. I found it to be open and inclusive allowing for good interchange of ideas and concerns.2) There are many beautiful trees that are sustainable.3) Reaching out to the community to offer beautiful, sustainable trees was a worthwhile way to show how various organizations can work together to benefit the community while trying to improve our environment.4) When dealing with homeowners that belong to an HOA, additional time and communication may be needed to assist them in obtaining approval for trees from their HOA's.

"I see tree planting efforts similar to what a trend of the future is to combat climate change and increase awareness of the importance of trees and tree canopies in our neighborhoods. Not only that but I see this project expanded to other cities in the county of San Bernardino. The continuity of this project is so valuable so that we can see the positive impact on the environment and the well-being of San Bernardino residents in the coming decades. I see this important work being organized and well-coordinated by involving the appropriate stakeholders at all stages of the planning project. It is about time to give back what we have taken for tens of years!" Husam Yousef

It was rewarding to see local homeowners excited about planting trees and grateful for the program providing them. Gail Sefl

an plants help cool our urban heat islands and mitigate impacts of climate change in our inland cities? I've been interested in measuring the temperatures of living and non-living surfaces for some time. Preliminary results are in! Use of dark asphalt, synthetic turf,
What can you do?
Take care of your trees, shrubs, groundcovers, and lawns to maximize their ability to cool the surrounding environment. In the same experiment described above, the coolest temperatures occurred in lawns growing in the shade of a mature tree. This is due to living plants cooling the environment during the process of transpiration. Non-living surfaces don't provide this natural air-conditioning. While many people believe lawns waste water, it's important to fully consider the alternative of replacing a water-efficient warm-season lawn like Bermuda or Buffalograss with either dark mulch or no living plants at all. The lawns are much cooler! Our previous UC studies determined that it's often not the lawns (and other sprinkler-irrigated plants like groundcovers) that waste the water, it's the uneven coverage (low distribution uniformity) of most sprinkler systems, coupled with not applying the right amount of water seasonally.
However, If you're tired of your high maintenance lawn and want to ditch your lawnmower, fertilizers, and pesticides, consider a low-maintenance drought-resistant groundcover that has similar cooling effects without the need for chemical inputs.
Plant drought-tolerant groundcovers
Here are just a few examples:
Peruvian Verbena (Verbena peruviana). This groundcover grows to only 1" tall and sports dark green leaves and white to pinkish (several hybrids available) blossoms that bloom from spring through fall. It spreads quickly and requires little water once established.
Dwarf Rosemary (Rosmarinus prostratus) This particular rosemary species is a low-growing groundcover. It is a great choice for rock gardens, reaching only 6 inches tall. It produces purple flowers in the summer and attracts pollinators and can be used for culinary purposes (bottom).
Gold Dalea (Dalea capitata). This semi-deciduous evergreen grows between 8" to 1' tall and has small yellow flowers that bloom in spring and fall and a pleasant scent. It is very heat tolerant and great for urban heat islands (parking lots, etc.) as well as planters and paths (lower right).

I became a University of California Cooperative Extension (UCCE) Master Gardener in San Bernardino County in January of 2019. I had learned about it from a friend who is an instructor with the UCCE Master Food Preserver program. She knew I liked gardening and suggested I look into it to see if it was something I would like to do. At the time I was working for a City Parks and Recreation Department in Planning and Design and my interest was increasing public open spaces and parks and gardens, knowing how essential they are to a healthy lifestyle. In another way, I was looking for an opportunity to get involved in the community. My interest in gardening and garden design just seemed like a natural fit for the UCCE Master Gardener program.
Within the UCCE Master Gardener program, I have volunteered in the San Bernardino School District (SBUSD), informational tables at farmer's markets, and more recently, with a non-profit after school program in Redlands called Micah House. There are two locations but the Micah House program on Oxford Street has been my main connection in the community, working with the mothers of after-school students on their vegetable boxes.
(The UCCE Master Gardener program would like to express gratitude to Micah House Executive Director Alison Anderson and the Chapel Street Micah House team for opening their doors to allow us to offer our 18-week training class there. In turn, Master Gardeners partnered with Micah House staff, families of their after-school program, and the community at large to transform a grassy area in their front yard into a lovely drought-tolerant garden through a grant from the Inland Empire Resource Conservation District.)
In one of my first UCCE Master Gardener activities with the SBUSD, I quickly became aware that it would be imperative to know Spanish well if I wanted to contribute to the UCCE Master Gardener mission to, "develop and extend practical research-based information in agriculture and natural resource to the residents and workforce of San Bernardino County." The US census states that 54% of San Bernardino County is Hispanic, and that 37% of the population speaks Spanish as their first language.
Thus, the story of how I needed to re-learn Spanish led to becoming the on-site UCCE Master Gardener at Micah House on Oxford Street. It began when I reached out to an extended family member who previously taught an immersive Spanish program and is the program director at Micah House on Oxford Street, for Spanish tutoring. After a couple of sessions, she asked if I might be interested in leading some gardening workshops in their vegetable beds started by the previous program director. Well of course! One hiccup. The mothers I would be instructing in gardening speak only Spanish and I want this to be inspiring, not complicated.
In the fall of 2019, with interpretation help from the program director, we set off together in planning the cool season vegetable garden with four mothers of children in the program. We were able to discuss the appropriate cool season vegetables and they selected the desired plants to grow over the winter. None had grown any of their own vegetables but were superb at gardening techniques such as weeding and planting. Much of gardening workshops can be a physical demonstration and then accomplished by the attendees, and I'm thankful for that because at this point my Spanish is still not up to a working standard!
With Spring coming, the program director had an idea how to include the children. We had an activity for them to plant seeds in recycled egg cartons, to be grown indoors as starts for the Spring garden. Again, the mothers were in the lead with selecting the warm season vegetable types and decided on a salsa garden.
With the help of the seed supply in the UCCE Master Gardener office, the kids were able to plant onion and jalapeno peppers. The mothers decided what to plant, install, regularly maintain. Harvest from the vegetable boxes are generously shared with their neighbors. Even with a few Spanish words, my sub-par communication skills seemed to go a long way with building rapport within the community and the workshops seem to be exciting for the kids and the vegetables are growing well! Fast forward to January, they are now harvesting cilantro, radish, lettuce, kale, and soon beets, carrots, and broccoli.
I like the personal benefits of gardening, doing something outdoors while getting a little exercise. Also, the learning and the organizational skills built on from one season to the next as you learn more about how plants behave in changing seasons. Watching plants form and develop over time makes it an activity of patience, as well, along with the maintenance lessons and mistakes. Before becoming a UCCE Master Gardener, I had experience in developing my backyard from a dead lawn to trees, shrubs, and flower garden (along with vegetable patch gardening). I believe the most outstanding thing I learned is the number of people volunteering in the community and the free resources UCCE Master Gardeners provide. I had not heard of the program up until then, and I think the program has many more ways to develop and transform in the coming years.
What I like best about the UCCE Master Gardeners program is the access to the science-based peer reviewed information regarding growing, pest management, and resources on plants and their requirements. It gives more confidence to the advice and recommendations I give in the community, which supports the work, rather than just relying on someone's personal experience with gardening. I think the first thing I would ask people interested in becoming a UCCE Master Gardener is whether they have a personality that likes to engage with the community. You can't stay sheltered away from the public while being a UCCE Master Gardener and you can't just have an interest in more information to be an arm-chair expert without experience. We test our knowledge in the community with questions they have or with activities which go along with instruction.
You may not have a natural desire for teaching, but you will need to have some interest in passing along knowledge with an open mind and appreciation for varying levels of experience in others. I tell people just because I have the UCCE Master Gardener badge does not make me a master of gardening -- it's the process of mastering, which never ends. I have a list of community service, both domestic and international. I've been involved with a City's Arts commission, 5k founder and organizer, an overseas director's assistant on a construction project, installed California Native gardens, community garden volunteering, and various past volunteer work with churches and work.
The purpose of this brief article is, even though you may think a little isn't enough, your efforts extended to the community can go a long way and grow into something you may not have planned. Stay open to opportunities and activities; you just never know where 'yes' will lead you.
