Hi, Julie. Thanks for taking the time to submit this information. Parrot feather is a tough plant to control, but I'd be happy to discuss the available options if your friend would like to email or call me.

I'm going to forward this information to staff at the Benton County Soil and Water Conservation District in the hopes they might have some additional resources to recommend. I'll let you know if I hear anything back from them.

Best Regards,
Vanessa Morgan
