[MAIPC] further questions about Oriental bittersweet vines

[Servis, Robert]

I would caution about trying to remove all roots, especially if it is more than just a vine or two.
Often times when we significantly disturb the soil, we only make the problem worse in terms of allowing other Non-Native Invasives to get a foot hold and establish. As we know, disturbed soils are a great place for invasives to take root.
If however, the vines are small and in low quantities, hand removal is possible, making sure to get all the roots out. After doing so I would press the disturbed soil back down with your boot, leaving it as "least disturbed" as possible.

I would personally cut the vine(s) as  flush/flat and close to the ground as possible and treat the still rooted, cut surface with a 25% solution of Garlon 3A if possible.  (25% Garlon 3A/75% water).  A drop or two of marking dye wouldn't hurt if you are treating multiple vines or are in a place where there may be contact by humans/pets, just so you and others can see where you have treated.
The closer to the ground the cut is made, the shorter the distance the herbicide will have to travel to get to the roots.  This will allow the best chance for the herbicide mixture to move to the roots in its full potency and hopefully provide you with the best results.

Just my thoughts. Hope its helpful.

>From description I understand that vines need to be pulled out all the way including roots etc.
After pulling vine undergrowth do you then need to apply herbicide to the soil to prevent regrowth?

Instead can vines  be cut part way  (e.g. 8-12 inches from the ground) and then herbicide applied?

I presume that pulling and getting all the roots is preferable to cutting.   Please advise.

Thanks.
