Dear Gary,

I am sorry to hear you have Italian arum since this plant is indeed nearly impossible to control without simply removing all of the infested soil! I would suggest isolating the patch and not letting it spread further by digging out outlying patches and clipping and throwing away flowers and seeds (in the garbage, not the compost). The Western Invasives Network Website has a forum dedicated to Italian arum control, I would encourage you to check it out for ideas and tip. Also if you have any experience you would like to share, please feel free to join the forum. Good luck, and thanks for reporting. We need to bring more attention to this nasty plant so it may in the future qualify for state regulation.
