Hello all,
This thing is coming over from the other-side of the fence. What is it?

Pics below. Is there anything I can do to curb it? How can I kill it, without damaging my rose bushes?

Looks like either a raspberry or blackberry sprout.

@BigBill

I was posting another pic when you replied. This pic has flowers, and... idk what.

Bill is right. Some kind of berry.

So will this thing kill my rose bushes? Will it wrap around the rose bushes, above ground? Or will it wrap around the rose bush roots?

Are my rose bushes in danger?

Can I plant other things or will this vine just kill it or outcompete anything I try to plant and grow?

Blackberry
they can be dug out(the roots are rather shallow )
also cut back and use a brush killer on the new sprouts.
If you use a killer it may damage the plants on the other side they have runners .

Interesting fact : roses and blackberries are closely related

The berries may be more vigorous than your rose and not allow enough light and other nutrients for you rose to thrive

You should remove the berries unless you want a berry patch ,....then move the rose

So if I use roundup?

Can I paint it on with a paint brush? And then wrap it with Saran Wrap or put a plastic bag over it, to keep it from spreading, will that kill it?

Or can I use some other kind of plant poison? Like casoron?

I will be getting rid of this berry plant. We have our minds made up about this thing, no matter what it is.

Hopefully, I can find a systemic that will kill it back to its roots.

If anyone can point me to a product that will kill it, that would be much appreciated.

I would clip them back to the ground. Then I would paint the fresh cut with a liquid plant killer. It will travel down the line and start to cause dieback
on the other side of the fence.

If you don't want to do that just keep cutting it back to the ground level. If you let it get established, other shoots will root and take off. Then you really have a problem.

That's what has happened. I neglected to take care of this problem over the years, and I am now paying for it.

I will do as you suggested BigBill, thank you.

I will do it to the 5 sprouts on my side of the fence.

As stated previously, if someone can recommend a product, that would be very much appreciated.

Thank you all

I am struggling to remember the name of what I have used in the past. I think it was something like shrub be gone or something like that.

I found it, Brush B Gone!

To kill a berry bush, cut it down and paint full strength Brush B Gone on the stems. Paint neatly, this will kill anything it touches. The only time to kill a berry plant is in the fall when it starts to go dormant. When the leaves begin to yellow, paint away. In the meantime, chop chop chop (but not until after the berries ripen. Yummm...).

PS: I think you have been watching too many late night horror movies. Next it will be popping out of the rose bush stems.

Who does the main bush belong to - you say it is coming under the fence, would you be killing your neighbor's plant (question mark key not working)

Mmmm. Technically I'm killing "my" plant since it's inside my property line.

My family doesn't want it there, and I will be using a systemic to kill it so it doesn't come back. It's growing through our fence, under our fence, and like the pictures show, it's even sprouting up in between my other plants. We want it gone. We've asked him nicely every year to cut it back, or trim it, or just control it. And he just waves his arms. Every year past, my mom had to dig up about a foot and cut the roots back to the fence line. With covid-19 it's even harder to be a good neighbor because everyone is practicing safe distancing and communication between neighbors is very limited. Especially on our block. Everyone keeps to themselves, even before covid-19. Have a few neighbors that are nice, cheerful, and respectful, but unfortunately, that neighbor is not. Don't know what other options we have.

It's ridiculous.

Idk I feel bad. I feel like I kind of vented in that last post. We are just exploring options. We won't take any action until Fall, if that's the route we take. We are also talking about moving. Or landscape renovation. So nothing is final. I keep telling my family to talk to a lawyer.

I'm thinking it would be like herbicide drift. That kills neighboring plants right? Tree laws don't apply. Covid-19 isn't helping. Idk what to do. That's a lot of work to do on my property to maintain a plant I don't want. And my neighbor is not paying my family to do it. Or paying anyone else to do it. Or taking care of it himself. Aaarrrgghh. *frustrated*

So, if you put herbicide on the parts on your side of the fence, it will suck it back through the roots to the bushes on your neighbors side. That can particularly be a problem if they *don't* die all the way, and someone on the other side is eating the berries.

Your best bets are severing the roots where they come through the fence, and a conversation with your neighbor. If he agrees it needs to be gone, you would be fine to use herbicide. Or you could move the rose bed several feet away from the fence so that your lawnmower chops off sprouts as they are getting started. There are various root barrier products out there, but I don't put much stock in them. Unless you want to build a brick wall many feet down, it seems like roots always find a way.

Neighbors can be real trouble. Ours grows a lovely crop of ragweed along our fence every year.

They have tried talking to the neighbor and were ignored.

If these were nice, experienced and sympathetic gardeners/neighbors, they would understand your plight and control the berry runners! But that ship 🚢 has sailed!!

For me step number one would be to chop off the runners.
If that did not provide the relief that you seek, step two would be to chop and paint with Brush B Gone. Let them worry about their side of the fence. So far they have given you no indication that they care. AND they are not likely to do so.
