This video, part II of II, explains how to do stem injections of invasive knotweed using the Green Shoots Stem Injection System. It follows Part I • Stem Injection of Inva... , which answers key questions about whether stem injection is the right method for treating your invasive knotweed stand.
0:24 - Personal Protective Equipment - what to wear when doing a stem injection.
1:09 - Selecting the dose for injections - making adjustments with the dosage adjuster.
1:29 - The dose used with 54% glyphosate concentrate - aquatic herbicide.

3:47 - Installing the needle.
4:34 - Choosing the path of treatment in the knotweed stand.
5:09 - Injecting in the stem, typically at the second node from the ground.

6:03 - Marking the stems with a paint marker.
7:02 - Treating small stems that can't be injected, i.e., stems less than 1/2 inch in diameter.
7:14 - One treatment method for small stems is using our small foam herbicide dispenser to do a direct application of foam herbicide to the small stems.
