Poor soil builds failure; TreeLife Urban™ builds forests!
Planting trees in the modern cityscape is far from simple. Beneath our feet, most urban soils are compacted, contaminated with road salts, and stripped of vital nutrients. This creates a hostile environment where young trees struggle to take root — and too often fail.
The impact is costly and visible: around the world, 20–25% of urban trees die within their first five years.
The result? Lost canopy cover, wasted budgets, and fewer green spaces to cool our cities and improve our air. This fact alone makes it critical in nature that the products and plants we select are suited to the function we need them to serve, and in our experience most bulk soils don't function very well, especially in tough urban environments.
At 59degrees Soil Architects, we’re changing that. Our mission is to turn lifeless, stressed soils into vibrant, living ecosystems — providing urban trees with the best possible start and helping cities grow resilient, healthy green architecture that lasts for decades.
The Urban Problem
TreeLife Urban™ doesn't just amend the soil; it ignites and supports a living, self-sustaining engine of fertility.
TreeLife Urban™ — Engineered for Urban Tree Planting Success
TreeLife Urban™ is the professional-grade solution to the toughest challenges in city tree planting. This bioactive soil amendment is scientifically formulated to build living, self-sustaining soils that give urban trees the best possible start.
Purpose-designed for use with the renowned Stockholm tree-planting model, TreeLife Urban™ integrates seamlessly into modern urban forestry practices — delivering healthier roots, faster establishment, and long-term resilience in even the harshest city environments.
• Ignites self-sustaining soil fertility
• Speeds up establishment (up to 4× root biomass)
• Works with existing site soils (no need to replace all substrate)
• Consistent, lab-controlled formulation

TreeLife Urban™ Built for Urban Realities
How it Works!
TreeLife Urban™ is the “AG1 for soil”—but it’s engineered for rigorous, professional use.
Purpose-built as a catalyst for soil autopoiesis, TreeLife Urban™ initiates a self-sustaining, microbially driven soil ecosystem, powered by high-purity, long-chain organic carbon.
This strategic carbon introduction fuels the formation of a resilient microbial network, actively binding soil particles, optimising nutrient cycling, and co-evolving in direct response to root exudates and other plant derived carbon inputs.
The BioComplete™ formulation delivers bioavailable carbon fractions and precision-selected microbial consortia. These components work in synergy, driving continuous soil regeneration, enhancing physical structure and porosity, suppressing soilborne pathogens, and establishing robust, lasting plant-microbe symbiosis. Unlike traditional, passive amendments, TreeLife Urban™ initiates an active biogeochemical feedback loop—where carbon sources, microbial communities, and plant roots dynamically interact to establish a high-functioning, living substrate.
The result: a resilient, self-organizing fertility system built to support sustainable urban landscapes at scale. TreeLife Urban™ empowers industry professionals with a data-driven, systems-level approach—ensuring that landscape installations achieve rapid establishment, superior root development, and long-term soil health outcomes.
TreeLife Urban™ Ignites Long Term Lasting Soil Fertility
To ensure a truly hospitable environment for root establishment, it is essential to have:
- High-quality organic matter that supplies a sustained source of energy and nutrients.
- A balanced spectrum of macro and micro minerals to support healthy growth and metabolic processes.
- An actively growing community of beneficial soil microbes that cycle nutrients, suppress pathogens, and interact synergistically with roots.
Trees thrive only when all these conditions are met—they rarely tolerate deficiencies or imbalances. For robust root development and long-term health, there can be no compromise: the soil must be rich in organic matter, mineral diversity, and microbial life, each working together to create the optimal ecosystem for trees to flourish.

Why TreeLife Urban™?
- Faster Establishment, Less Shock
- Trial results show trees grown with TreeLife Urban™ develop 4x more root biomass and approximately 2x more leaf mass, powering rapid establishment and resilient growth during the most critical weeks after planting.
TreeLife Urban™ is the complete planting substrate, crafted to transform urban tree planting success. Specifically created for city landscapes to ensures rapid root establishment to drive vigorous, resilient growth from leaf burst. TreeLife Urban™ is mixed at 20% by volume with your standard planting substrate—no need to source an entirely new medium.
