- Pre-emergents can help prevent the plant from becoming established, but it is generally more often encountered as a perennial problem.
- Contact herbicides are only partially effective. Glyphosate in particular needs to be repeatedly applied.
- Mowing is effective over time, if done regularly.
- Goldenrods are allelopathic to this plant. Smothercropping of buckwheat and winter rye will also weaken the plant considerably.
- Pulling must be done repeatedly over a long period, but will eventually kill the plant. Gloves should be worn.
- Smothering techniques such as paper mulch barriers are quite effective.
- Canada thistle should never be added to a cold-composting system. All parts of the plant should be burned, thrown away, or put into high-temperature composting systems.
