Commentary

Thanks for the report Amy! From the location provided I'm guessing this is on SW Northshire St. That is a county road and you can file a report at this address:

It looks like it is on the edge of the school, so you could let them know as well.

thanks,

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.
