How can I control weeds on my property?

1. Identify exactly what it is you want to get rid of. Use plant id guides or take a sample to your local CSU Extension office for identification.
2. Learn about the life cycle of your weeds in order to determine when the best time is to attack the plants.
3. Know that weeds can be controlled mechanically (mowing or shovel), chemically, or biologically. Find out what methods work best for the particular weeds on your property. It may be a combination of all three.
4. If you are unsure, call your local Weed District or CSU Extension for help.


What are noxious weeds?

Noxious weeds are non-native plants that disrupt native vegetation because they have no natural controls and are able to adapt to varied climate conditions. As a result of the Colorado Noxious Weed Act, Colorado noxious weeds have been placed on three separate lists: A, B, and C.

List A plants are designated to be eliminated everywhere in Colorado.

List B plants includes plants whose continued spread should be stopped.

List C plants includes plants in which control is recommended.

For more information on noxious weed lists, check out the Colorado Weed Management Association website.
