Himalayan Blackberry (Rubus bifrons) on Oct 29, 2019

Submitter does not have a specimen
EDRR Status: Local expert notified

Description of specimen

Out of control Blackberry bushes that are trying to invade 5 other homes.

Commentary

None

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.

Location

I believe this home is a rental and the renter has allowed the blackberries to cover almost the entire backyard. All of the neighbors are fighting to get rid of the branches that grow into our yards.
