Use native plants to replace stinkwort
As a professional, I have been converting weedy hillsides in Los Altos Hills back to native grasslands and wildflower fields. During that time, a new noxious weed, stinkwort, started growing along Interstate 280, then its seeds spread off the freeway onto town properties. Currently, Stinkwort grows along nearly every road in Los Altos Hills, and is moving into the fields around homes and soon will be in all of the Peninsula’s open spaces.
To manage this new weed, every plant needs to be string-trimmed or treated with herbicides, including Caltrans and Stanford University hills spraying their infestations, in August and September each year.
