Sarah’s post last week got me thinking about fall foliage. Everyone loves the changing colors, but until recently I didn’t know why it happened. There are three primary factors that affect fall color: the length of the day/night, weather, and leaf pigments.
Many people and (dare I say) authors of this blog cite energy savings as one of many benefits of healthy urban trees. But where exactly do these energy savings come from? The answer comes in two parts: trees benefit buildings immediately neighboring them, and they also benefit the surrounding city.
The Silva Cell product is designed for use in the urban environment, so integrating Silva Cells and underground utilities is an important topic to us. In a previous post we discussed basic design strategies and construction methods for integrating Silva Cells and utilities. The next question we’re most often asked usually starts something like this:… More
One of the most famous social science experiments of all time is the Stanford Marshmallow Experiment. This study, conducted in 1972 by psychologist Walter Mischel, examined the development of delayed gratification in children and the influence it had on their choices and success rates adults.
We had our first installation in France in the City of Troyes in mid-September, along Quai de Dampierre. The project was overseen start-to-finish by our Dutch partners, Greenmax.
Many of DeepRoot’s products are defined by their mil thickness. Our Geomembranes (Water Barrier and Bamboo Barrier), for example, have varying thicknesses of 30, 40 and 60 mil, while our root barriers are all 80 mil thick. But what is a mil?
This hydrograph (diagram showing runoff flow versus time) compares the intense spike of a stream during a storm in an urbanized watershed without adequate controls, with the “gentle rolling hill” appearance of a forested watershed’s response to the same storm. Note the loss of dry weather base flow for the stream in the urbanized watershed…. More
Here are this year’s photos from the Bartlett Tree Lab study comparing different planting methods for urban trees. For comparison, check out last year’s set. And for a fuller chronological picture, you can see all the photos up to that point in this post.
Back in January we posted about a project in Shoreline, WA, where the Silva Cells were being used to extend a sidewalk rain garden underneath paving. This stretch of the project is finally completed! It looks amazing, and we’ve got a case study to tell you all about it.
I’ve been growing bamboo since 1978 and have made many mistakes. Some species of bamboo doesn’t do well in Ohio, where I’m based, because they won’t tolerate the cold weather in winter. In some cases I’ve left the plants growing in my yard if only to show others what won’t do well in my climate. To control bamboo’s growth… More
Bamboo. It is great stuff. It is beautiful to look at, sounds neat in the wind, and makes a lovely privacy screen from your neighbors. You know the saying good fences make good neighbors (or good privacy screens make good neighbors). But if bamboo isn’t contained, those same neighbors you are trying to get some private time… More
The Christian Science Center, on Huntington Ave between Mass Ave and Belvidere Street in Boston, is the oldest suspended pavement installation that we know of in the United States. These trees were planted in 1968, making them 43 years old.
