Eradicating arum lilies

I have a problem in my garden: I wish to eradicate arum lilies. I have tried pulling them out of the garden, but they keep growing back. I have also tried spraying them with Round Up.


Arum lilies are not normally so difficult to get rid of. It may be in pulling them out you are leaving some of the root tuber behind. They need to be dug up, making sure you get all the tuber. I have done this very successfully myself.

Also, they do have seeds, so it's a good idea if you don't want them to self seed to remove the flower heads before they set seed.

You might try spraying them with Amitrol or Woody Weedkiller, both of which I believe should be successful.
