Q.How to eradicate dragon arum lilies from the garden.
When I first moved into this house, there was a single plant but now that other plants have been added and regular weeding, the dragon arum lily plants have multiplied to the extent they are a pest and need to be eradicated. I would like advice on how this can be done, thank you

A bit of research tells me you have a problem on your hands. Apparently the only solution that is known at this time is the use of powerful weed killers, and even that doesn't sound encouraging. Visit your local nursery and see what the latest thinking is on this invasive plant. Here's a link to a Washington state extension service article about eradicating arum:
