Commentary

Hi, Kate. Sorry to take so long getting back to you. As it happens, there have been some discussions in the last week about how to manage what you're seeing (which is actually knotweed; pokeweed doesn't have the jointed stems and tends to be pulpy/squishy, unlike hollow knotweed). There are some jurisdictional challenges that need to be worked out before we can proceed. Given that August-October is our normal treatment window, there's a chance we can still get to it this year.

Feel free to reach me directly (mitch.bixby@portlandoregon.gov) if there are other questions or concerns.

Thanks for the email.

-Mitch
