Commentary

Hi, Misit. Thanks for your email. Blackberry is a species that's too widespread for our Early Detection program to adequately manage. But look over some of the resources listed, and let me know if you have other questions about strategy or treatment. I'm at mitch.bixby@portlandoregon.gov.

Thanks again for your report!

Remedy

Himalayan blackberry has gone by many names in the Pacific Northwest, and there is yet a common consensus on which species are here and what to call the most dominant species. However, control options are similar.

they have a double plotted yard and the blackberry bushes are coming over all their barriers. The most I've seen in a while.
