We are offering a new product: a Stump Killer (see product). This product can be used right out of the bottle, i.e., no mixing required. It is perfect for those with a small number of weed trees to control. Here is our video explaining how to use it:

We launched our new website! Please take a look: Green Shoots.

Check out our newest video How to Kill Invasive English Ivy Vines: 3 Steps. If you like PowerPoint presentations better, here it is: PowerPoint How to Kill English Ivy Vines. We will be publishing another set of presentations on killing English ivy groundcover. For that we recommend a foliar or wipe application. English ivy can be a real problem in many parts of the world. It can climb tall native trees and eventually even kill native trees. As a groundcover, it also can out-compete natives. One thing: English ivy can be controlled in the winter when many native plants are dormant.
At Green Shoots, we sell concentrated weed killer and our foam herbicide dispenser systems help you
apply that weed killer precisely and with low drift. Concentrated weed killer or herbicide is not just more economical. It is also more effective.
Read this paper (link) from Bryan Young, currently a professor at Purdue about glyphosate rates. In it he says: “The most consistent application factor that can increase glyphosate efficacy is lower carrier volumes.” What does Professor Young mean by this? He means that by adding less carrier (i.e., water) and increasing the amount of glyphosate herbicide (i.e., increasing the herbicide concentration) in the spray solution, the herbicide is more effective. Moreover, this is the case even though an application may cover less of the target plant.
Take a look at the photos below and this video to see before and after images of weeds treated with low volume/high concentration applications: Video (link). As you will see in the foliar applications, very small amounts of herbicide are applied to very small areas of foliage (probably covering less than 10% of the green foliage). In spite of the small amount of coverage, the weeds were completely killed.

This presentation at the Upper Midwest Invasive Species Conference, 2014, summarized some of our control work on invasive knotweed at Southwood Nature Preserve in
Foam Stream Targeting Invasive Knotweed
the Twin Cities Metro area. It also briefly discusses use of our foam herbicide system by the Northeast Iowa RC&D where they have had success treating a large infestation of greater than 25 acres. Finally, Washington State
Foam Herbicide Clinging to Knotweed Leaves
University did some testing this summer comparing our foam herbicide dispenser to traditional spraying techniques. So far (and these results are very preliminary), the foam herbicide has performed better than the spray even though half as much herbicide was used on the plots where foam was applied. The full presentation is online at: How to Kill Japanese Knotweed.
As soon as we get data from Washington State University on their testing of the foam system, we will provide a link or other information.
We just added a new page with testimonials about our products. Here it is: Testimonials (link). They will give you an idea about what people are doing with our foam herbicide dispensers!
We launched our new website: Green Shoots. We have several new products on the website: our Large Foam Herbicide Dispenser; Foaming Agent; and Aquatic herbicide. If you are a professional or have a large piece of property with invasive weeds, you may be especially interested in our Large Foam Herbicide Dispenser.
We will also be adding a resource center in the near future. This will give you a link to our videos and other postings.
