Why is it a problem?
- Produces around 800 seeds per plant that are spread by wind, shoes, clothes, equipment
- Transported in contaminated hay and imported fill
- Displaces grasses in pastures and rangeland, outcompetes native vegetation and can create thick stands
How do I manage this plant?
- Mow or cut stems before they produce seed
- Pulling is ineffective because plants have a taproot, but they can be dug up with a shovel, taking care to remove the entire root
- A combination of manual and chemical treatments can be more effective
- Monitor and continue control efforts as needed
