If they were 3-4" in diameter, I could usually cut all of the roots within about 6" of the trunk, then push the small tree over. Quite satisfying, actually, I would then bag the berries for the garbage and burn the wood after it dried. For me, maybe one in 15 had deeper roots. If you decide to try this, you won't need to treat the shallow roots.; if you get a deeper-rooted one you could use triclopyr amine on the roots, let it dry, and then bury the roots | |

You can kill ALL of your buckthorn yet this year, then cut the trunks down as you have time. See here: aces.edu/timelyinfo/Ag%20Soil/2010/December/Dec_2010.pdf | |

I've managed other weeds by going after the leaves but this stuff is really nasty. They resprout very quickly and there are too many to keep up with. I'm really looking for non-conventional herbicides here but thanks for the answer. | |
