Never-Ending Thistle Control

It's that time of year again, when invasive thistle plants are thriving! In some cases, reaching over 4' in height and beginning to produce seed in heavily infested, unmanaged areas.


If the noxious weeds are left completely undisturbed for a growing season or two, they will have the opportunity to produce a vast network of spreading roots (rhizomes) and set seed, which will create a situation where complete control of the problematic plant will be just about impossible.

It is our opinion that thistle should be chemically treated with either a selective or non-selective liquid herbicide (site and product label dependent), by a licensed professional, and when the plant is actively growing. We have found that a targeted spot-application, performed just after the unwanted weed begins to grow and produces foliage (rosette stage), allows for the best possible control. With that said, due to the extreme root system of the thistle plant, multiple applications will surely be needed to kill-off any/all new plants, as they appear.

THISTLE PLANTS ARE NO JOKE!

Did you know that the State of Illinois has listed several varieties of thistle as a noxious weed and it's control is required by law.
