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.
Not only does it weaken and kill them, but the ivy morphs into the
adult that bears flowers and fruit, which the birds carry off and
spread. It's an invasive plant throughout its range, any extension
service that says otherwise is doing a disservice to its area.
