In the small park across the street, which is widely used as a dumping ground for garden refuse, two large patches of false lamium (Lamiastrum galeobdolon) are gradually growing and smothering everything in their path. What are my options for eradicating this plant? Are there sprayed herbicides that would take it out? One patch is behind a fence keeping people away from a dangerous cliff path...I can't get to it any way but spraying through the fence.
