A healthy tree can have a thousand infections. As long as they are properly
compartmentalized the tree will do well.
I school could be teaching the right way to prune a tree but their trees
could have been flush cut and painted years ago. Its going to take some
time to get out of the flush cut wound dressing era. Just as thought as to
why trees might not be doing well and the school is teaching correctly.
Also when we studied tree biology and ASU the people who cared for trees on
campus seldom attended the workshops.

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.

Most people have some illnesses, right? Same with trees.

If it is such a good school, why do they have so many sick trees?
