Garden Tool 

Eradicating blackberry vines may seem hopeless, especially if you don't want to use chemicals, but don't give up just yet. The Northwest Coalition for Alternatives to Pesticides advises gardeners to cut off the top growth, dig out the main root-ball, and then follow-up by mowing all new growth. Planting desirable plants to shade out the sun loving blackberries is also critical. Read the NCAP's blackberry management plan (pdf).
