<p class="MsoNormal"><span style="font-size:12.0pt">That plant is a monster. Italian arum is or was at the national arboretum (that's where I first got to know it about a decade ago). It's very hard to get rid of. It's best to dig plants up - you have to get
ALL the underground tubers and bag and dispose of the material in a landfill. You could leave it in the bags for a while to let it rot before disposal. It would be best to remove most of the soil in the area where the plants are, if that's a possibility. That
would help ensure removal of all tubers.<o:p></o:p></span></p>

technique?<o:p></o:p></p>
