The research has been out for a while now: circling, girdling, diving and kinked roots in the nursery pot lead to poor health, blown-down trees and shorter lifespans. With budgets for greenery shrinking, every tree or shrub has to last for a while.
Today is the second to last post of Peter MacDonagh’s five part series on the history of street trees in Holland. In this one, the Dutch expand their master planning to their pesky colonies. -LM Eventually the Dutch East India Company (VOC) controlled colonial trading cities in Asia, Africa, South America, and New Amsterdam in… More
Here is Part 3 of Peter MacDonagh’s series on the history of street trees in Holland. Things are starting to heat up! -LM The Low Country cities (which included both Holland and Belgium until 1830) went all in on the spice trade from the 1200’s forward. Most of these spices were harvested from the fruit… 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
For today’s post, experts L. Peter MacDonagh and James Urban, FASLA tackle one of the most commonly asked questions we hear about whether tree stability is related to an evenly developed root ball. Here is what they have to say. -LM Without a completely developed root system on all four sides, won’t trees fail? What… More
Every Monday for the next five weeks, we’ll be running a blog entry by Peter MacDonagh about the history of street trees in Holland (to see Peter’s fantastic series on the history of street trees in Paris, click here). Peter’s knowledge is incredible; I promise you don’t want to miss this unusual history of Holland… More
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. Final results and statistics are expected later this summer. In the meantime, preliminary results are so promising that we want to share… More
Today’s post is by Alison O’Connor, Horticulture Agent with Colorado State University Extension in Larimer County. It originally appeared on her blog, Co-Horts, and is reprinted here with her permission. Thanks, Alison! -LM Unless you’ve been vacationing in southern France for the past few weeks, you know that Colorado has had an interesting spring. I’m… More
(Read “Rise of the Curb Cut: Part 1 here). The fundamental behavior of stormwater in curbs and street design is simple. Each creature, each inanimate object, each molecule of everything functions and abides by its simple and powerful law every day: gravity. From this basic concept, direct parallels can be drawn between the design elements… More
Before anyone is lost to their thoughts or misgivings about the title of this post, this is not a piece on Germany in World War II or military strategies. Rather, this is about how odd parallels can be drawn between streets and nature, the built environment and natural one, and how an understanding of history… More
There are lots of ecological arguments for creating more green roofs, particularly in urban environments. Until now, though, I had never considered one additional benefit – certifying them as wildlife habitats. I started thinking about this after reading an item on the S.W.I.M. Coalition website about the Christian Reformed Church in North America (CRCNA) of Grand… More
A couple of years ago, I wrote hopefully about the City of San Francisco’s plans to revamp our main thoroughfare, Market Street. The project, which began in 2009 and planned to improve transit, pedestrian spaces, and business opportunities, represented a tremendous opportunity for Market Street to meet the grandness of its proportions. I hoped for… More
