When the Ray family bought the DeepRoot business in 1992, we only sold root barrier, Geomembranes, and ArborGard. Over time, the focus of the business grew as Graham and Julian brought on ArborTie. The business grew some more – actually, a whole lot more – with the addition of the Silva Cell in 2006. As these changes kept piling up, and as we shifted and… More
Here is Part 2 of Peter MacDonagh’s series on the history of street trees in Holland. Peter’s knowledge is incredible; I promise you don’t want to miss this unusual history of Holland through its trees. -LM The Low Countries, as one would guess, were perpetually wet – abounding with swamps, marshes and bogs. To increase… More
People accustomed to observing trees, especially in urban areas, find no shortage of dismaying situations to gnash their teeth over. Trees in too-small plots, buried root balls, broken and vandalized branches, poor stock, and unnecessary pruning are just a few of them.

In early June, the Portland Oregonian published an editorial titled, “Portland’s Cadillac Tree Plan.” In it, the board suggested that Oregon’s urban trees are doing great just the way they are, and argued that the city’s new tree code is costly and ineffectual. (The code was adopted two years ago but has not been implemented due… More

You’re invited to our third James Urban webinar this year! The topic is using trees and soils in urban stormwater management applications.
Back in December 2012, we reported the first preliminary results of Stormwater Treatment Performance Monitoring by Dr. William Hunt, Jonathan Page, and Ryan Winston, of two Silva Cell Systems in Wilmington, North Carolina.

I enjoyed drawing a lot when I was a kid. One problem I always had – and I’m sure this is not unique to me – is that my drawings always looked much prettier in my head than they did on paper. So for this slow, post-holiday Friday post, I wanted to share a video… More
It’s July 3rd, so I think I can safely assume that everyone who is at their desk is counting down until 5pm (or maybe 3pm, if you’re in the nice sort of office that closes early before a holiday). Here is a short quiz from the Morton Arboretum, “What Kind of Tree Are You?” to… More
