Yellow Iris - 6590 Aspen Dr. Sobieski, WI 54171

Location First Found
Hi Scott, I live in southern Oconto County and am battling what I have come to regard as an invasive specie. I bought it ~ 10 years ago from Scenic View Nursery and added to my landscape. After a couple of years experience with it, I decided to remove - to much green, not enough flower. While successful eradicating from land, I found it in the wetland on my property. I let it go for a while until I noticed how prolific it is and did some research. This last fall, I started trying to remove with Roundup, collecting seed pods and cutting. I have some confidence I can control in my immediate wetland, but am concerned about it�s spread. The water that flows through my property comes out of the Brown County Reforestation Camp and I believe eventually merges with the Little Suamico River. I have seen plants starting to appear downstream. I could use your advice and I fear help to control the downstream spread.
