Frost Cracks
If frost caused frost cracks, every tree in anyone area should have them.
They don't. But, when trees are present with internal cracks, and then
the
wood is suddenly cooled, the cracks spread outward.
I have dissected trees with deep internal cracks extending from old wounds
and injuries. Most cracks start from the inside out. There are cracks
that
do form from the outside in but they are not common and usually shallow.
Your tree had a serious wound.

Wrong. Many trees down here in Texas crack on the south side because
of the intense heat and lack of water. They do not crack from the
inside out, but the opposite. Without seeing a tree how can you make
such an assessment? You're kidding, right?

Ok, share you pictures of you dissections proving your point. You have
dissected trees, right? Just show me the pictures of your dissections.
Then maybe I will believe you.

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.
Some people will buy products they do not understand and not buy books that
will give them understanding.
