Introduction The first licensed airfield in Canada, City Centre Airport opened in 1927 on 144 acres of land just north of Downtown Edmonton. Serving as a military airbase during the Second World War, it became a stop on international passenger flights between North America and Asia in the 1950s. As jet technology progressed during the… More
From New York City’s Metropolitan Museum of Art to Wembley Stadium in London, DeepRoot has helped ensure the success of green infrastructure projects in big cities across the globe. But these high-profile initiatives are only part of our story — Silva Cells grow large trees in towns big and small, partnering with designers, engineers, and… More
A recent research study conducted by Bartlett Tree Research Laboratories tackled the question of the best methodology to grow trees in cities, with the ultimate goal of reaping benefits that mitigate the impact of climate change. The study (Comparison of Tree Responses to Different Soil Treatments Under Concrete Pavement) was produced by Dr. E Thomas… More
Introduction When we talk about low-impact development and design today, the term “suspended pavement” is frequently used — but rarely defined. It’s important to understand this practice within the field of green infrastructure, so let’s examine what suspended pavement is as well as its history, uses, composition, and case studies. What is Suspended Pavement? Suspended… More
One of the most common questions posed when beginning an urban forest project is: how wide do tree roots grow? According to studies conducted by Colorado State University, most tree roots occupy an area two to four times the diameter of the crown. Other research done at Iowa State University suggests that roots may extend… 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
A previous blog entry, Healthy Soils for Healthy Trees, discussed the importance of preserving soil structure from being destroyed by compaction. Together, soil texture and soil structure have the greatest influence on pore space in soil, and how easily air, water, and roots can move through a soil. Many people are aware of what soil… 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.
DeepRoot is key to the growth of urban forests everywhere for everyone to enjoy. Parking lots and car parks have not traditionally been designed with the health and longevity of trees top of mind. DeepRoot’s Silva Cell is intentional in creating more space and accommodating more soil where it is most imperative: at a tree’s… More
If you are of a certain age (like me), you remember when shopping malls were the place to be. However, online shopping and cultural changes have greatly impacted the popularity and profitability of malls, resulting in vacant storefronts and little foot traffic. Now, hundreds of “dead” and dying malls sit decaying throughout North America –… More
