Wound dressings stop rot. Nature is balanced. Fertilizer is food.
Wetwood is bad. Planting deeply is good. Rot is a major cause of failure.
Water causes decay. Insects and diseases are the major causes of tree
problems. There are at least a hundred more.



"Wound dressings" are no longer recommended, it ( as I always believed) is
not needed. Trees heal themselves fine without our "help".


Trees heal wounds is another myth. Heal is a animal term often used with
plants and trees. Trees compartmentalize wounds.

Healing is regenerating term while trees generate and not regenerate.

Trees seal not heal. About trees not requiring our help. When a tree is
wounded, trees cannot restore injured tissues in their same spatial
position. Trees are generating systems. Animals are regenerating systems.
http://www.treedictionary.com/DICT20...ng_system.html
Trees form new cells in new spatial positions as trees are wounded
throughout their lives. Heal means to restore in the same spatial position.
Animals are regenerating systems that form new cells, and new cell parts in
the previously occupied spatial positions. Healing and when injured,
animals speed up their normal regenerating processes, and this is called
healing. When trees are injured and infected they chemically strengthen
their boundaries that resist spread of infections in wood at time of
wounding, - reaction
zone -(http://www.treedictionary.com/DICT20...tion_zone.html) and then
trees form another new anatomical and chemical boundary that separates the
infected wood from the new healthy wood that continues to form - barrier
zone (http://www.treedictionary.com/DICT20...rier_zone.html. This
defense process in trees is called compartmentalization.
CODIT is a model of Compartmentalization (see A New Tree Biology and the
many research papers listed in this book that support this concept).

Adjustments to targets, is what the trees require. See "Tree Pruning"

More on generators and regenerators
Humans are regenerating systems. Trees are generating systems. Both
systems have good and bad points. generating systems do not heal wounds and
do not move. Generating systems are subject to the mass energy ratio. As
gens get larger in mass, energy needs increase as a parabolic curve. Gens
usually live longer than the regens. Regens move to avoid pain and
conflicts. Regens are almost entirely all symplast. Gens have a relatively
smaller symplast. Humans, regenerating systems. Trees, generating systems.
Humans come in groups but try to be individuals in families. Trees come in
groups, but very few ever reach maturity and reproduce. In the end, all are
recycled for new life as light drives the processes. Think about it.

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.
