It is best to hang dig Hairy cat’s-ear as soon as it appears, to ensure the crown is carefully removed. This plant is very persistent and will return after treatments due to its ample production of airborne seeds. It is possible to control larger infestations with repeated plowing, followed by reseeding of a non-invasive species or solarization – which means placing a plastic cover over the soil.
