I hope you don't like those large pine trees, because they'll be dead
sooner or later from the ivy.

Do you have the data that the ivy will kill a pine tree. I really know of
no data to establish that as a fact.
Sure it can block leaves and needles for photosynthesis. Other than that
what are you talking about?

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
