If the vines are in an area where you can spray, then just
spraying
with 3% Roundup will work. Or you can cut and then treat the new
growth with Roundup or one of the similar products made for weeds
and
brush. They are cheaper and more effective than triclopyr, which
is a
selective herbicide.
I doubt a 3% solution of Roundup will kill such a mature vine.
Have you ever tried it? I've routinely used it on mature poison ivy
and it works very well. On ground based poison ivy, I just spray it
on.
If it's a large vine going up a tree, with no accessible leaves, I cut
it, wait till new growth emerges, then spray it a month later. Never
had to brush it on.
In my experience the broad spectrum total vegetation type killers have
always been more effective than a selective herbicide, where there is
a
tradeoff on what it will and won't kill. For example, triclopyr is
used for clover control in lawns. It usually takes at least two
applications to control it. The first tends to just stunt it. If you
sprayed that with Roundup or another total vegetation killer, it
would
be dead the first time, but so would the grass.
As to the OP's question of future planting following Roundup, it's
safe
to replant a week after application.
Also in response to eggs info. I guess the bottom line is that I hate
messing with poisons. But sometimes it has to be done. I was
wondering if I could cover my 3 hostas, one mallow and a fern, with
double plastic bags and give it a good spray. This fall I will seed the
whole area with partial shade loving wildflowers. There will probably
be a battle for survival, but if I can just keep the nuisance stuff in
check, that would be a positive outcome, even if I have to keep whacking
and pulling some of it off.
Obviously if no leaves are allowed to remain, it would eventually die
off, but new invasive roots would move in from neighboring areas, but I
wonder how long that would take? Oddly, my son used to work for Chem
Lawn and sprayed the whole spot (I have other problem areas) with some
stuff that kills all vegetation for 5 years. I didn't like it then, and
somehow that fern survived that.
I potted up a little oak tree from the area and thought I was going to
lose it because the leaves were turning brown on the edges. Now I see
new leaves are starting to form in the tip.
Most of that stuff shuns sunny areas, so at least I don't have to battle
the stuff in the whole yard. It seems to like north, partial sun partly
shaded east, so far little or none in the mostly shaded west side of the
house, and none on the south. But those photos I posted, one is my next
door neighbor, and there is some on the south side of his house. That's
where it migrated from, most of it. They had a terrible problem with it
and ignored it for years, allowing it to develop massive underground
root systems. Now he has gotten rid of most of it because he completely
rehabbed the house and lawn, so in time, maybe we'll get it under
control.
I thought about planting black cap raspberries there. Would that win
the battle eventually if I keep it from climbing anything?
Thanks for all the good info and links.
Either herbicide will work. But I'd still recommend tryclopyr. It's
selective, as the googlegrouper said, but it's selective towards
woody,
broadleaf plants (exactly what you're trying to kill).
