|What is the best way to get rid of blackberries that have overgrown the area of the leachfield? I'm not concerned about killing the grass or other plants.
|Blackberries can be difficult to eradicate because they will sprout from the roots, however far away they've managed to travel. The good news is that you can kill them off with some persistence. First, if you mow them down and then mow them down at 2-3 week intervals all summer, the roots will eventually run out of stored energy and the plants will die. The important thing to remember is that every leaf a shoot produces will photosynthesize and provide new energy to the roots. So, mow them and keep them mowed and you'll eventually gain the upper hand. You can use chemical vegetation killers, to kill the plants off if you'd rather, but these products may need repeated applications (read and follow the label directions). Brush B Gon or Round Up are vegetation killers registered for use on blackberries. Good luck with your project!|
