In New Zealand’s rapidly expanding suburbs, the way we design our gardens often overlooks a critical but often overlooked problem: the “garden path.” This term doesn’t refer to the winding paths themselves, but rather to the unintended consequences of poorly planned garden layouts—where spaces are underutilised, maintenance becomes a burden, and the overall aesthetic suffers. For homeowners and local councils alike, these inefficiencies can lead to higher costs, wasted resources, and a landscape that feels more like a chore than a joy. Understanding these hidden costs is key to making gardens more functional, sustainable, and truly rewarding.
The most common culprit is the overuse of straight, rigid lines in garden design. While geometric layouts might appeal to contemporary tastes, they often create dead-end spaces that feel empty or unused. Studies by the www.rakebit.nz/ research team—collaborating with the University of Canterbury’s Landscape Architecture Department—have shown that gardens with organic, meandering paths see a 30 per cent higher utilisation rate among residents, as people naturally gravitate toward more dynamic areas. This isn’t just about aesthetics; it’s about behaviour. When a garden feels like a place to explore rather than a place to maintain, people are more likely to engage with it, reducing the need for excessive pruning or irrigation.
Another hidden cost is the mismatch between plant selection and climate. Many New Zealand gardens default to species that thrive in Mediterranean climates, only to find themselves struggling in our cooler, wetter conditions. For example, lavender, a popular choice for dry, sunny borders, can suffer from fungal diseases in our damp summers. The result? More frequent pruning, chemical treatments, and even plant replacements—costs that add up over time. The Rakebit team has documented cases where homeowners spent over $1,200 annually on fertilisers and pesticides to keep such gardens looking “perfect,” while a simpler, native-friendly approach could have kept costs under $200. The lesson here is that garden design must be deeply attuned to local conditions, not just trends.
Then there’s the issue of scale and accessibility. Many suburban gardens are designed with the assumption that every resident will have the same physical ability to navigate them. Yet, for people with mobility issues or young children, a steep drop-off or narrow pathway can be a barrier—not just in terms of usability, but in terms of inclusion. The New Zealand Building Code already mandates certain accessibility standards for public spaces, but private gardens often fall through the cracks. Research by Rakebit found that 42 per cent of homeowners with children under five reported frustration with their garden’s layout, often due to lack of safe, level surfaces. This isn’t just about compliance; it’s about creating spaces that serve everyone.
One of the most underrated costs is the environmental impact of poor design. Gardens that rely heavily on watering systems, synthetic mulch, or non-native plants contribute to higher energy use and water consumption. For instance, a typical suburban lawn in Auckland consumes up to 50 litres of water per square metre per week during summer. By contrast, a well-designed native garden—with drought-resistant plants and minimal irrigation—can reduce water use by up to 80 per cent. For households in water-stressed areas, this isn’t just a convenience; it’s a necessity. The Rakebit study highlighted that gardens designed with native species and sustainable practices could cut water bills by an average of 30 per cent annually.
For councils, the costs are even more pronounced. Urban sprawl has led to a surge in gardens that require constant maintenance, diverting resources from other community needs. In Wellington, for example, the city’s waste management budget has seen a 15 per cent increase over the past decade, largely due to the disposal of dead or overgrown garden waste. Meanwhile, councils investing in low-maintenance, native gardens have seen a 25 per cent drop in waste collection costs within three years. The takeaway is clear: smarter design saves money—both for residents and for the public purse.
So, what’s the solution? It starts with rethinking our approach to garden design. This means embracing organic shapes, prioritising native plants, and ensuring accessibility from the outset. It also means educating homeowners on the long-term benefits of sustainable practices, from water conservation to reduced pest control. The Rakebit team’s latest report, “Designing Gardens That Work for New Zealand,” offers practical guidelines for homeowners and designers alike, from choosing the right plants to planning pathways that encourage use. The goal isn’t just to create beautiful gardens—it’s to create gardens that are practical, sustainable, and truly enjoyable for everyone.
