Frequently Asked Questions

How do you kill Canadian thistle weed?

If you have Canadian thistle on your property, you're probably wondering how to get rid of it. This noxious weed is difficult to control because it has a deep root system that allows it to resprout after being mowed or pulled. The good news is that there are a few things you can do to kill Canadian thistle and prevent it from coming back.

One of the best ways to control Canadian thistle is to mow it regularly. This will prevent the plant from flowering and setting seed. Be sure to mow before the plant has a chance to produce seeds.

You may need to mow several times throughout the growing season to keep the thistle under control. Another way to kill Canadian thistle is to use a herbicide. Glyphosate is the most effective herbicide for killing this weed.

You can apply glyphosate to the leaves of the thistle plant using a pump sprayer.

What herbicide will kill Canada thistle?

There are a few different herbicides that can be effective in killing Canada thistle. Glyphosate is a popular choice, as it is relatively inexpensive and easy to find. Another option is 2,4-Dichlorophenoxyacetic acid, which is a bit more expensive but may be more effective in some cases.

Whichever herbicide you choose, be sure to read the label carefully and follow the instructions to ensure the best results.

What works best for killing thistle?

There are a few different ways to go about killing thistle, and which one will work best for you will depend on the severity of the infestation and your personal preferences. If you have a small number of thistle plants, you can simply pull them up by hand. This is the most environmentally friendly method, but it can be time-consuming.

For a more heavy-duty solution, you can use a herbicide. Glyphosate is a popular choice, but make sure to read the label carefully and follow the instructions to the letter; glyphosate is a non-selective herbicide, which means it will kill any plant it comes in contact with, not just thistle. Another option is to mow the thistle plants down repeatedly, which will eventually weaken and kill them.

This method is best for larger infestations.

Does Roundup kill Canadian thistle?

Yes, Roundup can kill Canadian thistle. This perennial weed is difficult to control because it has a deep root system that allows it to quickly regrow. Roundup's active ingredient, glyphosate, works by inhibiting an enzyme found in plants that is essential for plant growth.

When this enzyme is inhibited, the plant cannot produce the necessary proteins for growth and development, and eventually dies. Canadian thistle is especially susceptible to Roundup because it does not have this enzyme, making it an easy target for this herbicide.
