Hi Gerry. I have just built my dream home in the country on a large (3/4 acre) site. We laid the lawns last year but don’t know what to do with the boundry ditches as they are covered in brambles. Any low cost suggestions?
Cut them back with a slash hook … low cost, high exercise value … making sure to wear eye protection. The roots are then dug out with a spade or when they re-grow, spray with Roundup.
You can also just spray them as they are but you will have a lot of dead thorny stems. If they are out in the field from the ditch, get in a digger for a couple of hours to rip them out.
