I understand your point about leaving the tree alone, and in different cases agree, depending on the circumstances. I think chronology of cause and effect comes into play here, and blanket statements cannot apply to all situations.
The problem the OP has with his tree was never addressed by these comments. Just saying something might or could happen is dodging the issue. It could become a world-class tree if in the hands of the right artist. But probably not. The large knob needs to be reduced and letting the scar heal wont fix it. This knob needs to be carved and reduced. It may never callus over as big as it will need to be. But worrying about the regrowth piling up, or dieback further? To follow in your footsteps, sure it may be possible, but which method is more likely to resolve the OP's issue? I submit that simply allowing the tree to put on foliage and leave it alone will do exactly nothing to reduce that knob. It may eventually help it callus over the original scar after another 5 years in the ground. Maybe. But then all you end up with is a swolen knob with a callus over it. Not my idea of a good solution to the OP's question.
Can you please show me what "large knob" you are actually talking about?
Because, seeing that we actually collect and deal with a lot of collected material
down here which has had to have extremely large portions of the tree removed,
I am talking 4 inch plus branches...
I am just not seeing why you seem to be getting your panties in a wad over.
This tree's trunk can't even be much more than an inch wide at where the scar is...
which would make the scar not much bigger than a persons fingernail...
Not even a pimple on the ass of most trees.
You may disagree with what I have said to do and that's fine... My advice was
given on sound principals, that actually happen, not what if's, as you have suggested.
Yes, there very well could be dieback... it happens all the time, and yes scarring the
scar tissue could very well lead to further build up.
You may think if you want too, that this little "Mallsai" (as Vance would
put) it is going to be some world class tree if you want, "if in the hands of
the right artist"... which I guess it could, in about 50 plus years or more from now,
But regardless, why then would it matter how long it takes to heal over this scar ?
I think, where the issue lies, is that I have somewhere said something that you have taken
offense too, and you have now made it your "path of destiny" to try and follow me around and
try and point out all the flaws or problems that you see wrong with what I say. As if to try
and make me look bad... There is only one problem here and that is you might notice, that
out of the 2 of us... I am the only one here that has actually posted any trees that are kinda
worth a crap. So... who would you believe ???
I like having these discussions though...
