Hoping you are able to offer guidance for how to control a significant area of bittersweet. The photos indicate an approximately 36' x 36' area under a shallow-/girdled- rooted tree that, during the prior 3-4 seasons, I had focused primarily on hand pulling a thick carpet of Japanese stilt grass. However, I am now left with what I estimate to be ~75% coverage of Oriental Bittersweet starter vines. These starter vines are small. None have climbed the tree trunk yet. The remainder of the vegetation is barberry and wild rose and what is likely wineberry, which I have attempted to dig out. Also a few ash saplings, and some grasses, which frankly I'd like to try to keep in hopes to suppress the relentless stilt grass. Our "enemies" never cease, yes? I have read several cooperative extension articles regarding management, and I'm still a little confused as to how to proceed. The stems are very small... as in "stems," not "trunks." And there are literally at least... a thousand? of them? It seems mechanical (pull by roots) + application of foliar herbicide? What is the sequence of addressing? Do I spray foliage after July 1? and then wait to pull dying vines? Repeat for the next few years? All guidance is welcomed and greatly appreciated!!
