Use of herbicide next to wetlands.

Asked March 13, 2018, 6:10 PM EDT

Found this plant (Lesser celandine) in my yard and dug it up. My neighbors yard (adjacent to a wetlands) is infested with this obnoxious plant. Any pointers to rid before it gets out of their yard into the wetland region? Also they have dogs, so pets and natural body of water is a concern. All I’ve read so far is there are no herbicides for this plant yet. Is this true? If not, is there something safe for the two concerns I’ve listed above? Wasn’t sure how far away from wetlands is safe for herbicide use if there is something. We’re scheduled this weekend to work together to dig these plants/bulbs out and throw in the trash. Please advise to help us reduce the spread to the wetlands. Thank you.

Lesser celandine is a weed that is very difficult to deal with. Asking for more help near wetlands is a good idea. Perhaps you are in the Tualatin Soil and Water Conservation District? Contact them for more advice/assistance:
