By rot, I mean the development of cracks, fissures, cavities and holes
caused by the removal of wood caused by insect activity. I guess I used
the wrong term.

When you cut a large limb off a tree, the inner wood that you expose
*is* dead. The only living part of the trunk is the bark.

If the cut is large enough, it will expose dead wood, and that wood is
vulnerable to insect dammage and weather-related dammage (actual rot,
fungus, etc). This dammage may set in before the tree has enough time
to grow around and cover the exposed surface with new bark.

Silver maple is a garbage tree. The wood is soft because they grow so
fast. Surely you've noticed how they break during wind, and how fast those
things grow. Why you would want to save the thing is beyond comprehension.

I have lots of trees in my large back yard, and this tree is near my
back fence, it's about 30 feet tall, and provides privacy between me and
the apartment building across the street behind me.
If I could go to a big-box building store or nursery and bring home a 20
or 30 foot mature tree of my choice and plant it exactly where I wanted
it, like I can do with a flag pole or a mail box, then sure we'd all be
doing that.
But trees don't grow on trees (so to speak). We can put up skyscrapers
in only a year or two, but it takes decades for a tree to grow to the
size that you want them to be. Until we can easily replace mature trees
with other mature trees in a few hours or days, I don't think I'm going
to be cutting mine down because it's not exactly the tree I might want
in a given location.
If you ask me, we need more trees and fewer people on this god-damn
planet.

Not the OP-- but here's why I want *my* silver maple. It is 150
years old & has more character than I can afford to buy. It also
shades the back of my house and my patio.
It is messy-- it drops limbs, seeds, buds, and leaves during the year.
But it also provides a few gallons of sweet maple syrup when the
spirit moves me to tap it.

How long does it take to boil it down, and where do you do it?
