Introduction Municipal street reconstruction is often triggered by aging underground infrastructure: water mains, sewer lines, utilities, sidewalks, curbs, or drainage systems that have reached the end of their service life. But once a street is opened up, the project becomes more than a repair. It becomes a planning opportunity. Instead of simply replacing old infrastructure… More
Introduction Helping cities grow trees is what we do at DeepRoot — but it’s important not to think about tree count as the sole metric in achieving urban canopy goals. Thriving tree canopies are built one tree at a time, one project at a time, through individual decisions that determine whether a tree merely gets… More
Introduction: Supporting Tree Success with the Strongback With Silva Cells, the strongback — our temporary installation lid used during soil placement — is not an afterthought or a mere convenience: It’s an intentional design element that plays a critical role in how soil enters the system, gets compacted, and ultimately performs for trees. This Silva… More
Download our research overview document here. Today, the idea that urban trees need real soil volume to reach maturity is no longer controversial — it’s widely accepted among urban foresters and landscape architects. We also recognize that providing that soil volume, especially with systems like Silva Cells, represents a meaningful upfront investment. But decades of… More
Introduction Cities around the world are setting ambitious urban canopy targets, an essential step toward climate resilience and healthier public space. Yet many municipalities struggle to turn those targets into reality. As identified in a recent cross-city urban forest study, the disconnect is rarely a lack of vision — it’s a breakdown in implementation. One… More
Introduction People often ask us how Silva Cell grows large trees and treats stormwater. The truth is: it doesn’t. At least not by itself. Silva Cell isn’t some magical, mechanical device that generates roots or filters water on its own. Instead, it’s a simple yet powerful framework that lets nature perform at its best, even… More
Introduction Soil is the foundation for healthy urban trees. It provides essential space for roots to expand, creating conditions for a mature, wide-canopy tree — but only if it’s actually there in the quantity and quality the tree needs. That’s why soil volume is one of the most important metrics for determining a city tree’s… More
Introduction Why are streetlights and sidewalks considered municipal assets — but not trees? Most cities manage detailed inventories of their physical infrastructure: light poles, sewer lines, benches, trash bins, snowplows. These things are logged, valued, maintained — and budgeted for. They’re viewed not just as integral components of the public realm, but as long-term investments… More
Introduction Silva Cells grow healthy trees and manage stormwater in built environments all over the world — but there’s something especially meaningful about Silva Cell projects on school and university campuses. These spaces are more than just places to pass through — they often feel like a second home for students, faculty, and staff, who… More
Introduction Silva Cells were the first commercial soil cell product on the market, but did you know the idea of suspended pavement systems date back many years to urban European streetscapes? From Paris and London to Boston and Redwood City, let’s take a brief tour through the use and evolution of suspended pavement systems throughout… More
At DeepRoot, we’re very comfortable in the cold – in fact, Minneapolis is the home base for our technical and marketing teams (with even more hardworking DeepRooters spread across the Canadian landscape). This is equally true of our Silva Cells, which have been supporting urban forests and treating stormwater in some of the world’s coldest… More
Introduction The economic vibrancy of many downtown cores, particularly in small- to medium-sized towns, has been waning in recent decades, losing retail and residential ground to adjacent suburbs. The reasons why are complex — but there’s no denying that at least part of the problem is the space itself: downtown districts often feature outdated and… More
