At the nursery we are trying to rid the place of some of our autumn olive, Tatarian honeysuckle and buckthorn. With the ground still unfrozen and no snow, it pretty easy pulling out these invasive weed shrubs with a tractor and chain. At my house, I'm cutting off little trees that are encroaching on my plantings- shading them. Hopefully, alot of them will die once cut off. It may not be for much longer, however, that the mild December holds.
