By examining these diverse projects, the audience gains a broader appreciation for the ingenuity inherent in modern horticulture. The following sections delve deeper into the specific locations and design principles featured in the broadcast, offering a detailed look at how these remarkable environments were created and sustained.
Gardening Australia 2025 Episode 39
The Chelsea Australian Garden at Olinda
The broadcast begins in the Dandenong Ranges on Wurundjeri country, where host Costa Georgiadis explores a monumental achievement in landscape architecture. The Chelsea Australian Garden at Olinda is a permanent, upsized adaptation of the “Best in Show” winning entry from the 2013 Chelsea Flower Show in London. Designer Phillip Johnson, who led the team to that historic victory, describes the new site as a “natural encyclopedia” that allows the public to experience a design originally squeezed into a 220-square-meter plot, now sprawling over a generous 6,000 square meters. This massive expansion required significant engineering, including excavating six meters into the hill to create depth for garden beds and a central billabong.
A defining feature of this landscape is its sophisticated approach to water management. Johnson emphasizes that in a dry continent like Australia, water bodies should not remain static. Consequently, the garden’s central billabong is designed to fluctuate seasonally, mimicking natural cycles. A key element of this system is a stormwater engineered drain, which Johnson highlights as his favorite feature. Rather than channeling water away quickly, the design slows it down, capturing it to create a thriving ecosystem habitat. This sustainable approach ensures that the garden actively contributes to cleaning waterways, utilizing local plants like Nardoo, Baumea, and Water Ribbons to uphold water quality and provide habitat for frogs and other wildlife.
The garden is also a sanctuary for biodiversity, housing over 400 species of native plants, including nearly 100 that are threatened or endangered. Johnson notes that the site acts as an amplifier for conservation stories, allowing visitors to see rare flora like the Queensland Bottle Tree and Qualup Bell in a tangible context. Interestingly, Johnson reveals he is colorblind, a condition that influences his design philosophy. Unable to distinguish red flowers against green foliage, he focuses intensely on texture, light, form, and contrast. This perspective results in a garden that emphasizes structural harmony and the interplay of light, reminiscent of black-and-white photography, ensuring the space is visually arresting regardless of the color palette.
Tropical Intensity in Far North Queensland
Moving north to the humid climate of Cairns, the episode shifts focus to a private sanctuary in the suburb of Freshwater. Here, horticulturist Mark and interior designer Fairlie have cultivated a lush, foliage-driven oasis that thrives on the region’s intense rainfall—over two meters annually—and warm winter temperatures. Gardening Australia 2025 Episode 39 presents this space not as a wild rainforest, but as a curated collection of rare and exotic tropical plants. The garden is defined by its bold use of mass planting, where species like Licuala grandis fan palms, Philodendrons, and Sacred Bali Bamboo are grouped to create significant visual impact and structural shapes.
Gardening in the tropics is portrayed as a labor-intensive pursuit requiring a robust toolkit. Mark describes the necessity of using machetes and ginger knives to manage the rapid growth rates of plants like Heliconias, which must be pruned aggressively—sometimes removing entire sections—to allow new growth to emerge. The soil requires constant replenishment due to nutrients leaching away in the heavy rain, necessitating fertilization four to five times a year. Despite the challenges, including the annual washing away of garden paths, the couple views the constant renewal as a source of joy and a way to maintain physical fitness.
The collaboration between a horticulturist and an interior designer results in a garden that adheres to strong design principles. Fairlie explains that they treat the outdoor space like a lounge room, using plants to create vistas, focal points, and functional areas. Bright colors, such as the golden yellow of bamboo or the pinks of Aglaonemas, are strategically placed in shaded areas to draw the eye. The couple’s shared aesthetic ensures a cohesive look, where individual plant specimens are positioned to complement one another, forming a seamless tapestry of texture and color that spills out onto the street.
The Village Inside a Shed at Elevated Plains
In Central Victoria, Millie Ross introduces viewers to one of the most innovative concepts in the episode: the Daylesford Longhouse. Situated on a windy ridge at Elevated Plains, this 110-meter-long structure functions as a residence, a working farm, and a garden all under one roof. Owners Trace Streeter and Ronnen Goren designed the building to combine their passions for cooking, gardening, and self-sufficiency. The architecture protects the internal environment from the harsh elements, creating a microclimate that allows them to grow produce that would otherwise struggle in the region, including avocados, almonds, and apricots.
The interior of the Longhouse is described as a “village,” containing multiple dwellings, a central kitchen, and extensive garden beds that marry the architectural elements together. The sheer scale of the enclosed space allows for impressive vertical gardening, with fruit trees reaching the ceiling. Trace notes that the protected environment accelerates growth significantly compared to the outdoors. However, this Edenic setup comes with its own set of gardening hacks and challenges; the high humidity and lack of airflow can encourage pests, requiring constant vigilance. To mitigate this, the building features large sliding panels that can be opened to allow the structure to “breathe” and generate necessary air movement.
Productivity is a core theme of the Longhouse. The indoor garden ensures a supply of tomatoes by Christmas—a difficult feat in the cool Central Victorian climate—along with capsicums, chilies, and melons. The operation is a closed loop where nothing goes to waste; prunings are converted into fodder for the farm animals, mulch, or compost. In a humorous revelation, Trace admits that the apricot tree is so prolific that wheelbarrows of fruit are fed to the pigs when they cannot process any more. This segment illustrates the potential of diy gardening when combined with bold architectural thinking, resulting in a space that feels “fecund” and smells of life.
Whimsy and Resilience on the Limestone Coast
Sophie Thomson travels to the Eyre Peninsula to visit “Fiddlestix,” a garden in Coffin Bay that stands as a testament to perseverance. Owners Helen and Mike Bowyer have transformed a block of land defined by harsh, salty winds and a base of solid limestone rock into a colorful, quirky retreat. The creation of this garden involved immense physical effort; planting a single geranium often requires the use of a jackhammer and a crowbar to break through the rock, a process that can take an hour for a small hole. The excavated limestone is then repurposed into gabion walls and garden linings, turning a waste product into a structural asset.
The aesthetic of Fiddlestix is characterized by its playful use of recycled materials and vibrant color. Helen, a retired nurse, uses the garden as a canvas for “stuff and nonsense,” incorporating elements like a “wine garden” sunk into the ground for protection, and the “Great Wall of Coffin Bay” made from demolished jetty planks. Her husband Mike contributes sculptures created from old tools and colored bottles, including the “Mike-o-sphere.” These artistic additions ensure that the garden remains colorful and engaging throughout the year, even when the flowers are not in bloom.
Despite the challenging conditions, the couple has successfully established a mix of tough Mediterranean plants and natives that can withstand the environment. The garden layout is informal and evolutionary, dictated by where the rocks allowed them to dig. This organic approach has resulted in a space that Helen describes as vital for their mental health, offering a sense of pride and accomplishment. The segment highlights how gardening australia can be adapted to the most inhospitable terrains through creativity and sheer determination.
A Venezuelan Jungle in Western Australia
In the suburbs of Perth, Josh Byrne meets Daniel Antonio McLean, a landscape designer who has recreated the landscape of his childhood in a standard backyard. Originally from Venezuela, Daniel arrived in Australia as a refugee in 1997. His garden in Bicton serves as a profound connection to his origins, specifically the memories of fishing in the Orinoco River with his father. Gardening Australia 2025 Episode 39 explores how Daniel transformed a brick-heavy, heat-absorbing courtyard into a cooling tropical jungle filled with ponds, waterfalls, and lush vegetation.
Daniel’s design process involved removing extensive paving to reduce heat and amending the soil to support moisture-loving plants like bromeliads, papyrus, and bananas. He emphasizes the importance of creating shade and humidity to mimic a tropical environment within the dry climate of Western Australia. The sound of running water is a central element, contributing to the meditative quality of the space. For Daniel, the garden is more than an aesthetic pursuit; it is a form of medicine that has helped him manage post-traumatic stress disorder. The act of caring for plants, playing music to them, and witnessing their growth provides him with peace and purpose.
The property also features a productive verge and front courtyard where Daniel grows herbs, silverbeet, and custard apples. He views gardening as a way to save money and improve wellbeing, a message he is passionate about sharing. The contrast between the native and succulent plantings on the street front and the dense, green sanctuary in the backyard illustrates the versatility of garden design. This segment serves as a powerful reminder of the emotional and psychological benefits of cultivating a personal landscape.
The Collector’s Paradise at Woodgreen
The final segment of the episode profiles Peta Trahar, a landscape designer and horticulturist based in Bilpin, Blue Mountains. Her property, Woodgreen, is described as “heaven” and sits on rich black volcanic soil that allows for a vast array of planting possibilities. Peta’s approach to gardening is that of a collector; she treasures rare and unusual species, such as the Origanum dictamnus (Dittany of Crete) and the Neomarica caerulea (Apostle plant), the latter of which requires a clump of twelve leaves before it will flower.
Woodgreen is designed to celebrate the four distinct seasons of the region, which Peta likens to an orchestra. Summer brings hydrangeas, lilies, and heritage roses, while autumn provides natural color through deciduous trees. Winter reveals intimate treasures like her collection of Galanthus (snowdrops), and spring explodes with rhododendrons and blossoms. The garden layout relies on informal curves rather than straight lines, utilizing foliage texture and contrast to create depth. Peta emphasizes the importance of vistas, using trees like liquidambars to create ceilings that frame views through the landscape.
This segment touches on the evolution of a gardener’s mindset. Peta admits that she was once possessive of her rare plants but has learned the importance of sharing them with friends to ensure their survival—a lesson learned the hard way after losing precious specimens. She advocates for the conservation of exotic and native plants alike, viewing the genetic diversity available in Australia as “gold.” Her garden is a personal legacy, a space that has grown alongside her and provides a deep sense of belonging and permanence.
