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.

I assure you I prune properly, outside the branch collar and all the
cuts grow over the exposed wound. I will say it again, during times
of year when the insect vector for oak wilt is present, it is
recommended we use pruning paint. This is what Texas A&M p%rescribes.
It is only for live oak trees, and only during two months of the year.
The person harping is not me. I'm just preserving my old growth live
oaks to maintain the ecology as well as property value. In Texas,
large trees equals up to 20% of land vallue.

I did not mean to direct that question to you Billy.

Yes the cambial zone produces xylem to the inside and phloem to the out
side. Also, there is outer bark. I would ask the wound dressing pushers
how outer bark is formed and why some trees have smooth bark (beech) and
some do not (chestnut oak)? I would be ashamed if my pruning was so bad I
had to use wound dressing. Oak wilt is greatly influenced by flush cuts
and
wound dressing does not help trees close wounds. Some people just do not
understand trees. They will not go away or either will the wound dressing
idea. If someone on this news group prunes trees correctly please place
some pictures of your donuts of callus or wound wood after pruning to
prove
you know where the targets are.

Here is mine at bottom.

People that make flush cuts should not be allowed to prune oak trees in
Texas.
