Liam TaylorZach Galifianakis launched a gardening show on Netflix on 22 April 2026 — and within days, search interest spiked across Australia. This Is a Gardening Show is a six-episode series in which the comedian plays an earnest, bumbling amateur learning to grow things for the first time. It is charming, self-deprecating, and wildly entertaining. It is also, landscape and horticulture professionals warn, a gentle reminder of how quickly enthusiasm without expertise can go sideways in a garden.
What the Netflix Show Actually Shows
This Is a Gardening Show is not a how-to series. Galifianakis does not emerge at the end of each 15-to-20-minute episode as a reformed garden expert. He learns, makes mistakes, asks questions of actual professionals around him, and is honest about the limits of improvised enthusiasm. That format — the curious amateur, the patient expert — happens to map almost perfectly onto the consultation model that professional landscapers, horticulturalists, and home improvement specialists actually advocate.
Produced by RadicalMedia and Galifianakis's own Billios Productions and directed by Brook Linder, the show is shot around the comedian's rural Canadian property. It premiered four days ago and is already trending in Australia, where backyards are a serious cultural institution. The timing — arriving just as the southern hemisphere autumn gardening window opens — has given the series an unexpected relevance for Australian viewers with spades in hand.
The DIY Temptation and When It Gets Expensive
Autumn is one of the best times to tackle outdoor projects across most of Australia. Temperatures are cooler, soil moisture is better, and transplanted trees and shrubs have months to establish root systems before summer stress. It is also a season when hardware stores fill with enthusiastic new gardeners inspired, perhaps, by a four-day-old Netflix series.
Australian households spend billions annually on garden and outdoor improvement, encompassing both professional services and consumer products. The DIY segment is substantial — and so is the segment of that work that subsequently requires professional remediation.
The most common expensive mistakes professional landscapers encounter from self-directed projects fall into predictable categories:
Drainage errors: Incorrect grading and poor drainage installation can redirect water toward house foundations. Structural rectification is almost always more expensive than getting the drainage right initially.
Invasive plant selection: Australia has strict biosecurity rules around which plants can legally be grown, particularly in Queensland, Victoria, and Western Australia. Planting a species that turns out to be a declared weed — through good intentions and a bad hardware store label — can result in removal notices and significant costs.
Tree proximity: Planting large-canopy trees too close to structures, fences, or utility easements creates root intrusion problems that can take five to ten years to become fully apparent, and structural damage to pipes and footings that can be substantial.
Retaining wall failure: Poorly engineered retaining walls can collapse under hydrostatic pressure. In many Australian states, retaining walls above a certain height require a building permit and in some jurisdictions a structural engineer's sign-off.
What Professionals Actually Do That a Weekend Warrior Cannot
The Australian Institute of Landscape Architects — the peak professional body for landscape architects in Australia — distinguishes between aesthetic landscaping work and the technical disciplines that underpin it: drainage engineering, soil science, plant ecology, and structural design. A landscape architect or licensed landscape contractor brings competencies across all of these, in addition to knowledge of local council requirements, easements, and erosion controls.
This is not to say that a home gardener cannot safely plant a vegetable bed, install a path, or reshape garden borders. The practical line professional landscapers draw is between projects that change the physical structure of a property — earthworks, retaining systems, permanent planting that will affect drainage — and projects that add to it without altering it. The former carries engineering risk. The latter generally does not.
Galifianakis's show, to its credit, never pretends otherwise. Every time a genuinely complicated task arises on screen, an actual professional is consulted. The comedy comes from his willingness to ask questions rather than bluff. It is a more useful model than many home renovation television formats have offered.
What Australian Homeowners Should Assess Before Starting
If you are planning autumn garden or outdoor improvement work, a few questions help determine whether professional input is worthwhile:
Does the project change drainage? Any earthworks that alter how water moves across the property — including raised garden beds larger than a few square metres, or any re-grading — warrant a conversation with a landscaper or drainage professional.
Does it involve a retaining structure? In most Australian states, retaining walls over 600mm to 1,000mm in height (the specific threshold varies by council) require a permit. Higher walls typically require engineering.
Are you near a boundary, easement, or utility service? Plants and structures near property boundaries, underground services, or council easements can create legal and practical complications. Your local council's planning department and a licensed professional can clarify what applies to your block.
Are you in a bushfire overlay zone? Properties in bushfire-prone areas across New South Wales, Victoria, Queensland, South Australia, and Western Australia face specific vegetation management requirements. Tree and shrub selection near structures is not discretionary — it is regulated.
When to Call an Expert Before You Start
The ExpertZoom consultation model that Galifianakis inadvertently illustrates — curious amateur, patient expert, no pretence of knowing more than you do — is precisely the approach professional landscapers and horticulturalists recommend for Australian homeowners undertaking anything beyond basic garden maintenance.
A one-hour consultation with a qualified landscaper or garden designer before a significant outdoor project typically costs between $150 and $350, depending on the professional and the region. The cost of undoing a drainage error, removing an invasive species, or repairing a retaining wall failure is substantially higher. The Galifianakis heuristic — when in doubt, ask someone who actually knows — is good advice even when the stakes are lower than a Netflix series requires.
ExpertZoom connects Australians with qualified home improvement specialists, including landscape professionals, who can assess your property, clarify council requirements, and advise on project feasibility before work begins.
