Introduction The space constraints of dense city environments present a challenge for project planners implementing an urban forestry element. There are, however, a number of solutions to help improve conditions for healthy tree growth. The Silva Cells are one such choice, a suspended-pavement system allowing for maximum soil volume. Another option is structural soil —… 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 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
Following our post about critical questions to ask prior to using Silva Cells with existing trees, the following are a few examples of successful applications in the USA and Canada. As with any root pruning operation we always recommend close consultation with a local certified arborist. Gallant Ave | Deep Cove | British Columbia This… More
At DeepRoot, we promote large volumes of non-compacted, biologically active loam as essential for street tree health and longevity. Urban foresters generally adhere to the following minimums: 300 cubic feet for small trees, 600 cubic feet for medium trees, and 1,000 cubic feet for large trees. However, some municipalities are taking soil volume cubic feet… More
Trees do a tremendous amount for our communities in a number of essential ways. Unlike a streetlamp or a water main, their influence is diffuse— they affect everything from air and water quality, to flooding, to temperatures, to property values and incidence of crime. Urban trees are under more pressure and facing greater challenges to… More
