I keep pruning the suckers off the main trunk of our wisteria and they keep coming back. Also, I get a lot of suckers that appear to be growing from the roots of the vine around my yard and garden. Are there techniques or products that would help me control the suckers? I'm especially anxious to get rid of the ones on the roots.
