From Seed to Site: A Journey Through Scrub Nursery

Visiting Scrub Ecology Ltd at Scrub Growers Nursery is not just a tour of a nursery — it is a full journey through the life of a native plant, from tiny seed to thriving restoration-ready tree. The “Seed to Site” experience reveals the depth of planning, science, care, and trial-and-error that sits behind every planting project across Auckland and beyond.
Harvesting seeds: sourcing the future of our forests
One of the most important steps begins long before a plant ever reaches a pot. Seed collection is a highly skilled process led by experienced ecologists, including Jane Straka, who oversees Scrub’s native plant nursery and seed sourcing programme.
Seeds are carefully harvested from a wide range of locations across Auckland, including regional parks, ecological reserves, the Auckland Botanic Gardens (under permit), private land, and even Scrub’s own managed sites. This broad network ensures strong genetic diversity and resilience across planted ecosystems.
This approach — known as eco-sourcing — ensures plants are grown from local genetic stock, meaning they are naturally adapted to local soils, rainfall patterns, and climate conditions.
Why eco-sourcing matters
Getting eco-sourcing right is critical to long-term restoration success.
When plants are sourced from outside their natural ecological range, they may grow quickly at first but often struggle long-term. They can be less resilient to local pests, less adapted to environmental conditions, and ultimately less effective at supporting the wider ecosystem.
Scrub’s team has seen this firsthand. Trial and error over time has shown the difference between strong ecological outcomes and inconsistent survival rates. These lessons have shaped a firm commitment to local sourcing and ecological integrity.
Every success — and every setback — contributes to refining the system.
Planning ahead: the backbone of restoration
One of the most surprising insights from the nursery is just how far ahead restoration projects are planned.
Ideally, planting programmes are mapped out up to two years in advance, allowing time for seed collection, germination, propagation, and growth before plants ever reach a site.
However, real-world conditions don’t always allow for this. Funding cycles, weather events, and urgent restoration needs often compress timelines. Flexibility becomes essential — balancing ecological best practice with practical delivery.
Inside the nursery: systems, tracking and growth
Every plant at Scrub is part of a highly detailed production system.
Seedlings are tracked through every stage of their lifecycle, from germination to site readiness. Fertilising, watering, and growth data are recorded, building a complete history for each plant.
QR coding systems allow staff to instantly access this information, ensuring full traceability. It means every plant leaving the nursery has a documented journey behind it.
This level of detail turns restoration planting into precise ecological work rather than simple horticulture.
The potting shed: where precision meets care
The potting shed is the operational heart of the nursery.
Specialist equipment supports efficiency and plant health, including mechanical “fingers” that gently lift seedling plugs from trays before transplanting them into 1/4 or 1/2 litre containers for their next stage of growth.
Every step is designed to minimise stress on young plants and ensure strong, healthy development before they head out into the field.
Innovation in every season
Winter presents its own challenges in nursery production. Frost can be a serious risk for young seedlings, particularly in exposed propagation areas.
One surprising solution is a large automated fan system, designed to keep air moving through the nursery. This prevents frost settling on plants and mimics, in a controlled way, the protective microclimate of a mature forest canopy.
It is a simple but highly effective example of innovation driven by observation and experimentation.
From nursery to landscape: restoration in action
Scrub Ecology Ltd is not just a nursery — it is part of a wider restoration network working across Auckland.
Their work supports ecological restoration projects in local reserves, regional parks, riparian zones, and community-led planting sites. Each year, the nursery produces hundreds of thousands of native plants to supply these projects and support long-term landscape recovery.
If you spend time in local parks or regional green spaces, there is a strong chance you have already seen their work — from new native plantings along waterways to regenerating bush and restored ecological corridors. Much of what they do happens behind the scenes, but the results become increasingly visible as landscapes mature.
This connection between nursery production and field delivery is what makes their approach so effective: plants are grown with a specific site, ecosystem, and long-term outcome in mind from the very beginning.
The people behind the plants
At the centre of it all is Jane Straka, whose knowledge, curiosity, and willingness to trial new approaches has shaped much of the nursery’s success.
Alongside Rodney Straka and the wider Scrub team, she brings together ecology, science, and practical problem-solving. Their work is constantly evolving through learning, experimentation, and refinement.
This culture of innovation allows the nursery to trial new native species, improve propagation systems, and continually push the boundaries of ecological restoration.
From seed to site
The Seed to Site journey ends where it begins — back in the landscape.
Each plant leaving the nursery carries years of planning, care, and ecological intention. Once planted, these seedlings begin their next chapter: growing into forest, stabilising soils, supporting biodiversity, and restoring ecosystems across the region.
A visit to Scrub Growers Nursery makes one thing clear: restoration is not just about planting trees. It is about systems, patience, precision, and a deep understanding of how nature works — and how to support it.
And behind every planting site is a seed, a story, and a remarkable amount of care most people never see.
While the nursery is not open to casual visitors, we would like to extend a sincere thank you to Jane and the Scrub Ecology team for generously sharing their time, knowledge, and passion during the “Seed to Site” tour. Their commitment to ecological restoration and continuous learning is helping shape healthier, more resilient landscapes across our region.
