Because its leaves remain green long after others have changed color and fallen to the ground, fall is a great time to control buckthorn. Buckthorn will often have green leaves through November.
Small plants can be pulled by hand while larger ones, up to two inches, can be pulled using tools called weed wrenches. Bloomington Public Works has a variety of these tools available for residents to check out and they can be reserved by calling 952-563-4920.
Dealing with the roots is very important. Buckthorn will resprout vigorously if left alone.
