I’m yet to see ivy kill a tree. I don’t get why people think this happens. It can certainly make them look ugly though.

I've seen it and then seen the resulting dead tree fall on my house. Tree was already dead from ivy by the time I bought it. When I finally went back to cut it out, the biggest ivy were like 14cm diameter or bigger.

This is what I mean. Maybe the tree was just dead? How do you know the ivy caused that?

I’ve seen it a bunch of times, but it’s almost always because the accumulated weight and size of the ivy makes the tree fall over in a good storm

I think that's called a goat

or a pig

I would totally put a goat back there if I was able to. Probably would have to own the goat though because it'd just come back every few months.

But… blackberry bushes are the good kind of invasive!
