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
It is hard to tell just by looking at a tree-lined street, but soil and its microbes — in combination with trees — can form a powerful system for improving stormwater quality. Some pollutants are filtered or retained by soil, while others are taken up or transformed by plants and microorganisms. The U.S. EPA’s 2023… More
At DeepRoot, helping trees thrive means supporting them throughout their development — from their first days after planting to the mature canopy they can become. We manufacture ArborTie because the establishment period deserves careful attention. Temporary tree support may be a small part of a planting project, but when it is needed, choosing the right… More
We get asked to compare Silva Cells to CU Soil with some frequency. It’s a comparison that we always hesitate to make, because to us it’s really a case of apples and oranges. While they may seem to be solutions to the same challenges, there are some very significant differences that affect their value and performance for tree growth… More
Introduction The question of how much soil is required to grow a big tree is one that has been debated among arborists and landscape architects for decades — and the answer isn’t black and white. Space, pollutants, and engineering requirements are all major considerations that affect the growing conditions of urban trees. And, other than… More
You don’t need much experience in arboriculture or landscape design to notice that planting trees in cities is very different from planting trees in forest environments. There are many reasons for this, but perhaps the biggest is the difference in composition of the soil.
– Dortmund Square in Leeds City Centre was refurbished with Silva Cells at the base of a London Plane Tree in 2013. The results, eight years later, are stunning. – Leeds City Council endeavored to refurbish the square located off the Headrow by improving walkways, street lighting, and seating to open and enhance the space… More

Mosquito Creek Watershed in North Vancouver is a unique natural retreat nestled within a large urban footprint. The area is a popular retreat for hiking, mountain biking, and walking, and leads directly to the Trans Canada Trail, the longest hiking trail in the country. Due to its proximity to the City of North Vancouver, however,… More
Back to laboring over here at Deep Root HQ. Mike James of Deep Root Canada Corp., snapped this picture in Vancouver in 2010. Looks like a group called the Stick Shift Project — “a collaborative act of urban transformation” — has taken the engines and other guts out of four cars and replaced them with… More
A big part of this blog is devoted to the discussion of trees, soil, and stormwater in the urban context. Today we want to walk through the three processes that allow trees in uncompacted soil to provide stormwater quantity and rate control benefits: Soil storage Interception Evapotranspiration
Soil. Stormwater. Sustainable Infrastructure.
