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
