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
Susan Day and her team at Virginia Tech published a paper earlier this year about a soil rehabilitation technique called Soil Profile Rebuilding, or SPR. They were looking for a way to rehabilitate soils damaged by land development in a way that would restore their biological function and be more supportive of plant growth. I… 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
To quote DeepRoot Vice President Al Key: “No matter the issue, trees have an impact.” This axiom is certainly true: Thriving urban forests are an important feature of any healthy city. The environmental advantages of these trees are obvious, everything from carbon sequestration and stormwater management to air-quality improvement. Even the financial impact of these… More
Introduction Trees have often been called the lungs of the world for their respiratory-like ability to release breathable oxygen into the air. But they could equally be considered the liver of the world, as they also filter atmospheric toxins and make the air cleaner and healthier to breathe. Urban areas typically feature worse air quality… More
Introduction Did you know that there are enough parking spaces in the United States to fill up the state of Connecticut? There are approximately 2 billion parking spots in America (servicing the needs of about 200 million cars). On average, a quarter of every major city’s land is parking area — with some cities, like… More
Cities at the Forefront Biodiversity, the mix of animal and plant species in a given region, is an important measure of environmental health and a crucial component of conservation efforts. Traditional thinking on biodiversity has viewed cities as its antithesis — a disturbance to the natural environment where life organically thrives. And there’s no doubt… More
