To kill the vines growing up the trees, cut the ?trunk? of the vines in a couple of places near where the vines emerge from the soil to remove a section of vine. This will kill everything upward from that point. The vine will resprout and you will later need to spray the resprouts and the smaller vines throughout the area with a product containing glyphosate (such as Roundup) at the strongest label rate. This will knock it back well but some will resprout. When it gets a few leaflets out spay it again. This herbicide is translocated into the roots and kills smaller vines while severely damaging stronger ones. Repeat applications will eventually get them all. Later summer to early fall is a good time to make a final application as the vines are storing sugars for the dormant season ahead. Herbicide applications seem to be more effective at that time.

Thanks for the question. Please stop in again soon!
