[MAIPC] Italian Arum

[Jil Swearingen]

Ruth,

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.

Here's a good fact sheet from the State of Washington.

Thanks,

Jil
