Italian Arum (Arum italicum) on Mar 11, 2018

Submitter does not have a specimen

Description of specimen

It's growing all over my backyard and I'm having trouble getting rid of it. My attempts at digging it up didn't work.

Commentary

None

Remedy

Italian arum can be difficult to eradicate once established. Make sure to wear gloves and long sleeves and pants when removing it, as its sap can cause skin irritation. Do not compost or put in your yard debris, as this can lead to spreading of tubers which can grow into new plants. Home control methods can include carefully digging out the tuber and any daughter tubers and disposing in the trash. Cutting and disposing of the berries in the trash can help prevent spreading to new sites. Herbicide trials are still inconclusive, please contact your local Soil and Water Conservation District if you are interested in chemical control.
