I’m actually talking about this vine, not a specific situation. It’s all over the place at my new job, and it needs to be removed. Unfortunately, many of our volunteers are….folks of a certain age. And digging up vines in the woods is not the sort of thing you want to set a pack of septuagenarians onto. So, I’m trying to convince a service group they want to come down and yank it up for us.
Bittersweet was introduced to the US as an ornamental (sound familiar?) in the 1860s. Some background from the Alien Plant Working Group:
“Oriental bittersweet is a vigorously growing vine that climbs over and smothers vegetation which may die from excessive shading or breakage. When bittersweet climbs high up on trees the increased weight can lead to uprooting and blow-over during high winds and heavy snowfalls. In addition, Oriental bittersweet is displacing our native American bittersweet (Celastrus scandens) through competition and hybridization.”
Most publications I see suggest Roundup is successful at control–can anyone attest to that first hand? I’m skeptical it will be that easy, since bittersweet is so woody. But we have over 20 acres to deal with, so…a little chemical control would be welcome.
Frustratingly, seeds apparently persist for 2-3 years after removal, so this is a long term project. And, of course, if our neighbors don’t remove their vines…
