People's understanding of trees and their systems is so distorted.
We take all the mulch area away that trees desperately need.
Even though, wherever trees wander, that essential mulch territory; is the
only thing they take with them; wherever they go. Then almost in
mockery, we take a tree and territory over and may throw a small patch
of mulch down against the trunk. The only place; the mulch doesn't go,
then do it too deep! Like we sense the mulch goes there somehow; but
miss the target. The mulch is an essential territory of, barrier,
protection, environment stabilizer, refuse disposal, garden etc. in a
breathable layer for the roots and ground. This familiar territory is
essential to maintaining low stress in the magic of supporting and
maintaining the longest lived, largest and tallest of any life born ever;
for that is a big job!. Many things done to trees; that really, are
like we've caged them proudly, tightly into our world, rather than letting
them live in theirs. Placing starved for mulch, too deep, the only
place it doesn't go is just one example of that misunderstanding of their
simple and essential mechanisms to be the wonder to live so long, and so
large; but only in a land of plenty...
As always the ideas that it doesn't matter
how we abuse etc., shine not to be true. In that the ground element is once
again very important, and in fact has 2 areas of consideration. Against the
trunk soil height should never be changed, microscopically by design trunk
tissue is distinctly different from even top woody root tissue. The second
area of consideration, is the ground area over roots, not against trunk;
this tissue can as said take soil and mulch covering. but only minimally, as
the roots, and all of the life conditioning and feeding soil for roots.
Trees evolved in groups, and their line of
spars would bar out or limit larger animals walking all over soil sea
garden. Small patches could become compressed, and the mychorhizae would
carry the rich nutrients from the more uncompressed gardens in the forest
system to the less fortunate trees with compressed soil sea gardens; not
working and feeding the tree as efficiently. but, this would not of course
make up for the lack of microscopic burrowing activity to condition soil to
more permeability and holding of more life space/air spaces in the soil
