How to Get Rid of Thistle - 3 Tips

Tall thistles should not be sprayed with weed killer. Too many nearby desirable plants will be killed. Use the Green Shoots Foam Herbicide Dispensers to apply a concentrated, precise amount of weed killer to the cut stem of the thistle.
0:00 Introduction
0:34 - three tips for killing tall thistles
0:39 - 1st tip: cut the thistle near the ground
0:44 - 2nd tip: apply foam herbicide within about 1 minute of cutting the stem.
0:50 - 3rd tip: use a concentrated herbicide solution such as glyphosate with 20% active ingredient.

The Green Shoots foam herbicide system – available from greenshootsonline.com/ - has several advantages over conventional spray systems. First, it is highly precise and selective. The foam can be discharged very slowly and placed on the target location. Second, once placed on the target, the foam herbicide sticks to the foliage or plant tissue of the thistle. It doesn’t drip like liquids from a conventional spray system. Third, the foam herbicide dries slowly. This increases translocation of the herbicide so that the roots can be killed. Fourth, the foam herbicide is highly concentrated. This ensures that the mixture is sufficiently powerful to do the job. As explained in the video, using Green Shoots foam weed killer is easy. The herbicide can be placed directly on foliage of the thistle – either the green leaves or green stems. Alternatively, if you want to remove the thistle immediately, you can cut them and apply the foam herbicide to the remaining stump. If you do a stump application, be sure to apply the foam herbicide immediately after cutting. Thistles have extensive root systems, so be sure to apply the foam herbicide to each stem that you can find.
