Think about all the beliefs and treatments that were false. Before the germ
theory, people believed that diseases caused microorganisms. Babies were
thought to be fertilized by liquids from the male. The earth was thought to
be flat. The sun was thought to travel around the earth. Best to put warm
materials on burns. Bleeding a sick person gets rid of the nasty things
inside. The gods lived in Olympus and did all things. Wound dressings stop
rpt in trees. Flush pruning is best because the wounds heal faster.
Drilling holes to let out wetwood and stop decay. Planting trees good and
deep is good for trees. Trees heal wounds, roots regenerate, and trees have
root flairs. The list is long with tree practices and with many other
practices. It is a wonder people and trees are still around! The
frightening part of this is that false beliefs come easier than the truth.
many myths and misunderstandings are still with us. To erase a myth is very
difficult, yet to add another myth is easy. Dr. Shigo read many books and
magazines, mostly about science. The beliefs come and go in science also.
If others can have beliefs, why can't we? Further, we find it difficult to
understand how people inside can write about systems that grow outside? We
do not believe trees can be understood by looking at them only from their
outsides. Until Andreas Vesalius began systematic dissections of human
bodies, the myths about our bodies were many. Until tree anatomy, not wood
anatomy, is learned, we will be in the same position with trees. Wound
dressing is a very silly idea.

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.

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.
