This week on “In the Garden with UC Master Gardeners”, we take you to a remarkable success story of pairing core elementary school learning and a school garden.  Master Gardener Bill Brooks traveled to Laguna Beach’s Top of the World Elementary School and talked with fellow Master Gardener and teacher Kelly Osborne.  Imagine that through a simple school garden, the varied concepts of Mathematics, History and Social Studies, and of course, Science are incorporated into this remarkable outdoor classroom.  Learning outdoors is a key element of student excitement and engagement. The sense of pride when the students see their garden’s bounty featured in the school cafeteria is immeasurable. The surrounding community also benefits and contributes when they purchase the products and produce made and grown at the Top of the World School Garden’s Farmer’s Market.

It is time for another installment of what to do in the garden this month for the month of September on “In the Garden with UC Master Gardeners”.  Despite the likelihood of heat outside, work may be necessary to start CLEANING UP the garden. Out with the old!  Prep for transition to Cool Season color and crops.  Be aware of  the Fire Season danger potential. Look for bulbs now for planting in October.  Dethatch your lawn or consider PLANS for removing lawn in exchange for drought-tolerant plantings.  That project will take more than just plant material!  Irrigation is a giant part of the plan for lawn removal.  Next month, we’ll say “IN WITH THE NEW” as October will be a better month to plant!  UC Master Gardeners Teena and Katrina are at their best giving advice on monthly garden tasks.

Not to be confused with the chocolate treat, today on In The Garden with UC Master Gardeners, we are talking about Truffles - the mysterious yet delectable underground fungus. Truffles are mycorrhizal fungi which play an important role in the health of soil.  The truffle/tree relationship is beneficial for both the environment and for the tree.  Because they grow underground, their aroma and flavor are tantalizing to both humans and animals. Today we’ll learn about how truffles are being cultivated and then how to cook and enjoy them.  UC Master Gardener Host Bill Brooks recently spent this episode with his expert guests located across the country - Dr. Tom Michaels, trained as a Plant Pathologist and expert on EVERYTHING Mushroom and Truffle-related.

Now is your chance to understand the classic example of METAMORPHOSIS! Simply imagined, the word means changing structure, form, or substance. A word which applies to this process could be “supernatural”.

 What does gardening have to do with the University of California? Quite a lot! The latest episode of In the Garden with UC Master Gardeners explores the science, education and community service behind the UC Master Gardener Program.  In “Rooted in Research: The UC Master Gardener Program,” host Bill Brooks talks with Randy Musser, Program Coordinator for the Master Gardeners of Orange County, about the many ways the University of California helps Californians make informed decisions about gardening, agriculture, natural resources and environmental stewardship.  The program highlights the work of UC Agriculture and Natural Resources (UC ANR), the University of California Cooperative Extension, and the UC Master Gardener Program. Listeners will learn how UC research is translated into practical, research-based information that can be used by gardeners, homeowners, schools and communities throughout California.  Musser also discusses what Master Gardeners do, how the program serves the public through workshops and educational outreach, and what it takes to become a UC Master Gardener.  Tune in to discover how a statewide network of university researchers, educators and volunteers is helping Californians grow healthier gardens and communities—while putting science to work right in the backyard.  In the Garden with UC Master Gardeners airs Thursdays from 8:30–9:30 a.m. on KUCI 88.9 FM in Irvine.

Gardening is more than a hobby—it’s a natural way to nourish both the body and mind. Growing your own fruits and vegetables makes it easier to enjoy fresh, nutrient-rich produce picked at its peak, while spending time in the garden connects us with the living world around us.  Healthy garden soil contains diverse communities of beneficial microorganisms, and our interaction with natural environments may support a healthy relationship with the microbes that live around and on us.  Gardening is exercise, too. Digging, planting, weeding, lifting, and walking through the garden build strength, flexibility, balance, and endurance. Reaching, bending, and stretching as we care for plants can keep our bodies moving in ways that feel productive rather than like a workout.  Perhaps one of gardening’s greatest benefits is mental health. Being outdoors, working with plants, watching seeds grow, and enjoying the sights and smells of a garden can help reduce stress, encourage mindfulness, and provide a wonderful sense of accomplishment.  Join Master Gardeners Bill and Artemesia to explore how gardening may be one of the healthiest things you can do - because when you grow a garden, you are growing a healthier you, too.

This week on In the Garden with UC Master Gardeners, we air a much-needed show on the topic of pest control.  Integrated Pest Management, or IPM, is the primary tenet of Master Gardeners’ philosophy regarding pests. The key word is “INTEGRATED”.  According to the UCANR.edu website, Integrated Pest Management is “a process you can use to solve pest problems while minimizing risks to people and the environment.”  Master Gardener Sally Richards met with retired UCANR advisor Dr. Cheryl Wilan to talk about pesticides – their labels and proper use. Plus, some direct methods like squishing, squashing, and drowning!  All methods are part of Integrated Pest Management!  Just as your plants are hungry now, so are the pests that bother your plants.  Feed the plants and you are, in turn, feeding those bugs that eat the fresh new growth.  Stay on top of them the moment you spot them. Look up what you find on our UC IPM (Integrated Pest Management) website for specific pest notes at Pest Notes Library / Home and Landscape / UC Statewide IPM Program (UC IPM). Another indispensable resource is our Hotline Gardening Questions? - Ask Us! | UC Master Gardeners of Orange County.

 Plumerias (aka Fragipani)!  Maybe the most coveted of the tropical flowers grown and blooming now in Southern California.  These flowers are more likely identified as Hawaiian as they are a favorite flower for leis, but they are actually endemic to Mexico and Central America.  They thrive in Southern California’s Mediterranean climate with a little water.  Even inland regions of Southern California are HOT spots for plumeria culture. This week on In the Garden with UC Master Gardeners, Master Gardener and host Bill Brooks talks with fellow Master Gardener Pennie Louwers and past President of the South Coast Plumeria Society Jaki Kamphuis about how to grow plumerias. Learn all you need to know about the needs of the plants (water, temperature, soil, feeding, and propagation) to get you off and growing.

 On “July in the Garden” Master Gardeners Teena Spindler and Katrina Kirkeby are at it again to tell our listening public about what to do this month.  The heat is expected for the next two months so, control of the water is the key.  Manage your sprinkler system.  Make sure the water soaks deep enough into the soil.  If changing from a hose or an overhead sprinkler watering system to a drip system method, you will be surprised how much longer a drip system needs to run in comparison!  Consider planting a second round of summer crops.   The episode discusses gardening in shade as well as care of turf during the summer months. Have fun gardening in July.

Master Gardener Host Mark Oertel sat down with fellow Master Gardener Teena Spindler and discussed Heritage and Pass-Along Plants.  We call them that because these are plants that have been given or taken another person, and that person is often someone close to us.  This is a plant or a descendant of a plant that has been lovingly cared for or admired from afar.  You know what I’m talking about.  That blue iris that blooms “out of the blue” telling you that someone is looking down and smiling upon you today!  You may have inherited your family home and would never, ever consider digging up any of the beautiful plants your parents or even your grandparents tended for years.  You know the feeling, right? On the other hand, think about what you have in your garden that you cherish and would like to share with someone! They will remember you forever! But also remember this. Be aware of the regulations and common sense around sharing plants that may be either invasive or simply unclean in terms of pests and diseases. Share with love!  Listen in and smile!

 “In the Garden with UC Master Gardeners” Explores “Landscapes as Nature” on KUCI 88.9 FM.  Reimagine your outdoor spaces with an inspiring new episode titled “Landscapes as Nature.” Host Teena Spindler welcomes special guest Ron Vanderhoff of Roger's Gardens in Newport Beach for an engaging conversation on the growing movement toward naturalistic landscape design.

This episode highlights how landscapes can function as living ecosystems. Known as “landscapes as nature,” these designs mimic native environments by incorporating layered plantings, diverse species, and regionally appropriate vegetation. By prioritizing native plants, gardeners can create outdoor spaces that are not only beautiful, but also sustainable and supportive of local wildlife.

Listeners will learn how to design with layers, variety, and texture—combining groundcovers, shrubs, and trees to reflect the structure of natural habitats.

“Landscapes as nature blend human creativity with ecological function,” says Spindler. “This approach helps gardeners create spaces that are both resilient and deeply connected to the environment.”.

 This week “In the Garden with UC Master Gardeners” on 88.9 FM KUCI Irvine explores the captivating world of bromeliads.  In this episode, Master Gardener Bill Brooks sits down with Cristy Brenner, President of the Saddleback Valley Bromeliad Society, who shares her deep passion and decades of experience with these unique and eye-catching plants. Brenner, who has been “addicted” to bromeliads since 1995, offers listeners an engaging look at why these plants are gaining popularity—especially among California gardeners.

Bromeliads are exceptionally well-suited for California’s climate. As waterwise plants, they thrive with minimal irrigation, making them an excellent choice for sustainable landscapes. Their long-lasting blooms provide extended color, but it is often their striking foliage—featuring bold patterns, textures, and colors—that truly steals the show.

Listeners will learn about the remarkable epiphytic nature of many bromeliads, meaning they can grow without soil by attaching themselves to surfaces like trees, walls, or mounts. Whether displayed in pots, nestled in rock gardens, or artistically mounted, bromeliads offer versatile design possibilities for any garden space.

Beyond their beauty, bromeliads are also incredibly easy to care for. They are low maintenance, have few pest problems, and require little to no fertilizer, as they absorb nutrients directly from the air. Even more appealing, bromeliads “keep on giving” by producing offsets, or “pups,” allowing gardeners to expand their collection over time.

Discover how bromeliads can transform your garden into a low-water, high-impact oasis.

 California is almost ten years into the legislation, planning, and implementation of one of the most significant environmental plans ever developed. Senate Bill 1383 was passed in 2016 with the goal of diverting methane-producing organic waste from California’s landfills. This week on In the Garden with UC Master Gardeners, our intrepid host and Master Gardener Bill Brooks met up with David Tieu, Central Region Deputy Director of OC Waste and Recycling recently to talk about what the regulations mean for residents of Orange County and beyond. This is a show we are calling Composting and Organic Waste in Orange County. Your city may have already started a waste bin system requiring the household to separate its waste three ways. The bottom line for the discussion of organic waste is this – It is illegal to put organic waste in the landfill bin. Waste management companies have been turning your household green waste into thousands of tons of certified disease and weed-free compost and mulch! And then, they provide the finished product back to residents for  pick up so we can replenish our gardens!  This mulch and compost is free of charge. You can leave the composting to your trash haulers if you don’t want to deal with composting yourself!  Regardless of the state you live in, many municipalities across the country are implementing programs like Orange County’s.

 The hot and dry season can occur year round in California.   Our intrepid “In the Garden” host Master Gardener David Letourneau is bringing you a much-needed episode called “Creating A Defensible Space Against Wildfires”. David talked with OC Fire Authority representatives Teri Merritt, Fire Prevention Specialist / Wildland Pre-Fire Management and Captain Larry Kurtz to bring you new ideas plus all the recommendations to help keep your property safe from an oncoming wildfire. Beware of Mexican Feather Grass, a very popular landscape plant ,but it is now considered invasive and a fire hazard.   Those dead palm fronds up in the canopy easily catch fire. “Oily” plants like cypress are drought-tolerant but very flammable. Brush clearance 100 feet from structures is the rule of thumb. This may require cooperation from your neighbors so be a good neighbor and listen in on what to do to be safe from wildfires.

Have a small space and love to grow food? A reprise of a popular show on “In the Garden with UC Master Gardeners", our beloved former “In the Garden” host Mark Fierle spoke to an icon of the gardening world – Mel Bartholomew. In this show, first aired less than one year before Mel passed away - Mel talks about his visionary concept called Square Foot Gardening. From learning what went wrong in his community garden, Mel developed a space-defying, compact design to solve the weed problem in his community’s row garden.  Most people now have vegetable gardens in raised beds, and it was Mel’s engineering background and ability to solve problems that led him to engineer the Square Foot Gardening method.  It has enabled people around the world, including people with disabilities and the blind, to feed themselves as well as to enjoy the joys of gardening.

In the Garden presents a new episode titled “Garden Innovations at The Giving Farm,” hosted by Bill Brooks. In this episode, Brooks explores groundbreaking work happening at Westminster High School’s The Giving Farm.  Located on the campus of Westminster High School, the Giving Farm is home to a vibrant eight-acre farm and orchard that has become a model of innovation, education, and community service. This dedicated team of UC Master Gardeners in Orange County developed an orchard management program designed to streamline essential tasks such as fertilization, pruning, and pest control—ensuring long-term tree health and productivity.  A standout feature of the program is the use of QR-coded signs placed on each tree, linking visitors directly to easy-to-use care guides. Master Gardener Ronald Cheung led the thoughtful design of these signs, combining in-depth horticultural research with accessible information to help every tree thrive. The result: healthier trees, stronger harvests, and increased fresh food donations to support the Orange County Food Bank.  Our Master Gardeners refer to SCREC in the episode, and that means the South Coast Research and Extension Center in Irvine, California.  

Beyond orchard management, the Giving Farm initiative has expanded to include nutrition education, culinary connections, and even the rich history of the fruit grown there, helping students and the community understand not just how food is grown, but why it matters.

“Garden Innovations” highlights how collaboration, technology, and passion for service can transform a school farm into a powerful resource for education and hunger relief.

You might be anxious to revamp your garden layout. You might want to try a method that will put issues like pest control, soil quality, and accessibility all in YOUR hands! The subject of this edition of “In The Garden with UC Master Gardeners” is Raised Bed Gardening. Master Gardener Bill Brooks got together for a long-distance interview with a fellow Master Gardener from Colorado who is an author, media creator, educator and innovator. His name is Scott Wilson (AKA Gardener Scott). Bill and Scott will compare and contrast what it is like to garden in Orange County, California, compared to the 7000-foot-high environment where Scott lives and grows. The concept is the same, but challenges may be quite different. But the similarities win out! With the soil management from season to season, there is no need to worry about replanting the same crops in a bed year to year. There are ways to control underground pests and rodents. 'Intensive planting’, ‘Succession planting’– key phrases discussed here to help you incorporate beautiful, raised planting boxes in your regular garden too! Remember, you are in control! With help from Mother Nature of course!

The topic this week on “In the Garden” with UC Master Gardeners is Bird-Friendly Gardens. We join Melissa Rapp, a current UC Master Gardener AND Executive Committee President at the Sea and Sage Audubon Society on bird friendly gardens.. Melissa will bring us up to current times at Society based in the San Joaquin Wildlife Sanctuary across the road from UCI off Michelson (Riparian View Road). They maintain a 6600 sq. ft. demonstration Pollinator’s Garden which benefits hummingbirds and native bees. The focus of today’s conversation will be how you, the home gardener, can maintain a safe environment for birds as they feed and nest, and what are the best varieties of plants (mostly natives) that attract local birds to eat and create their homes in your garden! Find out more about the Society and their resources by visiting their website.

It’s time for This Month In The Garden for the month of March.  The key emphasis at this time of year are three words: Plant, Feed, and Control. But don’t jump the gun.  Remember to think about what plant you want where.  By knowing what you want to plant, you’ll know the type of fertilizer you will need.  Think about TOMATOES! How are you going to keep them off the ground? Teena and Katrina have wonderful suggestions and techniques for trellising or caging your plants. More than just tomatoes need support so what they describe can be used year-round.  Annual and perennial flowers! Yarrow, Coreopsis, Globe Amaranth, Rudbeckia. Look up how big they get so you can avoid overcrowding or planting tall varieties in front of short. Plumbago! There is a reason they are used as freeway plantings! 6' to 15' tall x 6' to 8' wide! Beautiful blue flowers that bloom for most of the year.  Just as your plants are hungry now, so are the pests that bother your plants. Feed the plants and you are, in turn, feeding those bugs that eat the fresh new growth. Now we talk about CONTROL. Stay on top of them the moment you spot them. Look up what you find on our UC IPM (Integrated Pest Management) website for specific pest notes.  Just put UC IPM in your search engine.

26 Miles Across the Sea!  This week on In the Garden with UC Master Gardeners, we head that way with Master Gardener Bill Brooks. Bill spent the day talking to various plant propagators at the Catalina Conservancy’s Ackerman Native Plant Nursery about starting native plants from seed to repopulate the natural landscape of Santa Catalina Island. Over 85 species of container stock and over 2000 seed collections that represent 243 species are grown/housed at the nursery. All the projects conducted at the nursery are controlled under protocols that are strict enough to avoid negative impact to the special and unique environment of the island. There is more to Catalina than Avalon! Join us and learn techniques valuable to the rest of us on the mainland and to understand what there is to love, garden-wise, about a local environment just “right over there”!

Citrus is a $3.3 billion industry in California, and it is currently under threat from one of the tiniest insects and the disease it carries. In this episode of In the Garden with UC Master Gardeners, we will detail the threat of the ACP (Asian Citrus Psyllid) and HLB (Huanglongbing or Citrus Greening). If infected, the tree will die. The threat started by the simple practice of sharing and moving plant material between gardens (and even countries). Doing so can unknowingly spread the disease. Since the introduction, there are currently quarantine zones covering from the coast of LA and OC to the mountains and out into the Inland Empire. Pockets of agricultural land in San Diego County and Ventura Counties are impacted. The boundaries are expanding. ACP is known to infest CA trees from Kern County on east and south to the border. Hear from Jennifer Pelham, (former) Horticulture Advisor of UCANR (University of California Agriculture and Natural Resources) on this subject.

Aquatic plants are those that can be found in any salt or freshwater environment - a small fish tank, home aquarium, lake, pond, water feature - you get the idea. Whether they live above the water, are fully submerged in water or somewhere in between doesn't make too much of a difference. The main concept is that aquatic plants are any species that naturally prosper in a wet environment. Our own Master Gardener and Podcast Host Bill met with fellow Master Gardener John, an enthusiast turned expert turned entrepreneur, to talk all about the subject! If this topic suits your passion, get your feet wet today and don’t worry about your plant! They LOVE wet feet!
