New toy for VTA diagnosis

[Andy Clark]

Im going to sheepishly ask how its used for pruning recommendations? is it to do with branch angle?

 

 

Yes Ben, in two aspects (sort of).........

 

If you look at the pic - the right hand one of the two triangle shaped cut outs in the middle, is basically a protractor. Set at 25 degree angle.

 

This is the "sort of" nominal angle between a fork for determining the likelihood of an included union - anything less than 25 deg. is likely to become (if not already) included (BAD), anything greater than 25 deg. shouldn't become included (good).

 

The other is the overall shape of the tool itself - that kind of sectioned pyramidial shape.

 

This is "sort of" the nominal crown shape of a tree.

 

Before the buffs start ripping that description to pieces, I'm gonna emphasise now the amount of "sort of"'s that I threw in there.

 

As a lot of folk who know me will know, one of my fave sayings is "there are no straight lines in nature", and I know VERY well that it's not THAT simple to just determine all trees are the same and act/re-act the same etc.

 

You have to take into account Ben, the differences between .species, growth habit etc, and remember that the tool is just no more than exactly that.... A tool.

 

It's only as good as the bod using it.

Double the length from the middle to the end.

Where can you buy the template? Can't find anything about it online from a quick search?

Vid was a good watch and the tool looks useful.

 

There's a thread here:

Where post 11 has a link to a power point presentation (Slide 7) which (it I'm reading it right) appears to challenge the thinking for what might be considered a safe / unsafe union. Or am I reading it wrong??
