I recently presented a webinar where I discussed three high-impact design decisions that affect long-term tree performance: tree spacing, sizing the tree opening, and water harvesting into soil below paving. Attendees asked a lot of good questions, and by far the most asked one had to do with the use of tree grates. As anyone… More
Cities are the cultural and economic centres of the world whose progress depends upon effective management and evidence-based policy making.” – ISO 37120 Briefing Note “Unless someone like you cares a whole awful lot, nothing is going to get better. It’s not” – Dr. Seuss, The Lorax Cities are growing rapidly and we all have a… More
One of the questions I am most frequently asked is, “How often do you root prune?” This is a tricky question and one for which I wished there were a more clear cut answer. First let’s dispel a myth. Ready? Ok, here it is. We do NOT root prune every tree in the nursery. (Take… More
In part 2 of this series, I gave an example of an i-tree study that analyzed the Chicago Region and encompassed seven counties. But i-Tree tools work on a much more granular level as well, so today I want to discuss about a study that looks at just one city: my hometown of Minneapolis, MN…. More
We’ve all taken shelter under a tree’s canopy during a storm, grateful for its ability to intercept rain. You may not realize this, but rainwater that passes through tree canopies is modified both volumetrically and chemically in processes that have been relatively well studied in forests. That modification, which encompasses several different components, is what… More
In anticipation of the American Society of Landscape Architects tradeshow later this week, today we’re highlighting an iconic tree planting project using suspended pavement – including archival photos and original section details – that took place in Denver in the early 1980s: the 16th Street Mall. -LM Denver has long been a place of significance in the… More

Mississauga Civic Centre is a 37,280 square meter complex that houses the Mississauga City Hall, a towering monument of post-modern architecture designed by Edward Jones and Michael Kirkland that opened in 1987. Although it received numerous accolades, the surrounding campus and Civic Square suffered from mid-century design perspectives on public spaces, catering toward keeping people… More
I meet many people in the landscape architecture community who have heard of i-Tree… but don’t really know what it does. Basically, i-Tree is a suite of tools designed to quantify the structure of a community forest as well as the environmental services provided by that forest. It can be used at a wide range… More
Production/manufacturing nerds, this one’s for you! We regularly get questions about how and where we manufacturer Silva Cells to meet target performance requirements. I asked our Director of Operations, Rebecca Stevens, to discuss the various steps involved in our quality control process. -LM By the time a Silva Cell order is received by a customer, it is simply a necessary… More
My window looks out on 9 Mile Creek, a rural looking creek in an urban/suburban environment in Minneapolis/St. Paul, Minnesota. In the six years our company has been here, this is the closest I’ve seen water come to the parking lot. For a number of weeks this spring and summer, the large ash trees on… More
