My yard was full of blackberry bushes. We used one of the brush demolisher machines and got them cut but I know they will come back. There were too many to dig up the roots. I want to spray the stems but don’t want to use Round Up. Can you suggest a product that will illuminate them without killing me in the process.

Thank you for your question. Do you mean the invasive Himalayan blackberry? If so, here is a publication with ideas: https://s3.wp.wsu.edu/uploads/sites/2064/2014/02/Himalayan-Blackberry.pdf If you are referring to another plant, please clarify. Thanks!
