Thanks for contacting Ask Extension
Unfortunately, this weed is an extremely hard one to eradicate.
There are no biological methods and a natural control only reduces, it does not eliminate.
Natural control:
The use of cultural practices, such as increased mowing height, fall fertilization, and overseeding to enhance cool-season turf density and vigor may help the lawn to outcompete nimblewill infestations.
Pesticide control:
Herbicides have been developed for this for selective control of this weed, but not for application by an unlicensed home owner. If you decide to treat it, contact a lawn company and let them know you have a specific need. It will take a minimum of three treatments.
Your other option is to use a product such as glyphosate (Roundup). For best results, apply when the plants are young and actively growing. However, because nimbleweed is capable of re-establishing through surviving stolons, at least two glyphosate applications are recommended, but three or more may be needed for complete eradication. It is important to allow the weed to regrow before making any follow-up applications.
Once you know it has been destroyed, you can replant your lawn. This method is used by homeowners in small patches where the weed is the most prolific.
These are a few references that might give you more guidance.
Good luck.

Thanks, I’ve got a huge area of it and killing it and reseeding is not an option. I have been following your other suggestion now for four years without much success. I had heard that Tenacity was effective. Is that not true?

Good riders will hear their horse talk, but the best horsemen hear them whisper.

Yes Linda it is true. But I believe only a licensed lawn person can get this.. you might check if it is available now
Thanks. Just FYI it’s available on Amazon. It is extraordinarily expensive, however!
